ARRL Contest Rule Changes, Clarifications Reflect “Best Practices” in Radiosport

Wed, 07/26/2017 - 15:01

Just ahead of the 2017-2018 contest season, ARRL has announced rule changes and clarifications to League-sponsored contests. These include an improved process for submitting logs and reporting scores. Unless otherwise noted, these changes become effective starting with the September VHF Contest.

“These changes reflect current ‘best practices’ in the contest community and help us improve the quality of the competition and reporting of results,” ARRL Contest Branch Manager Bart Jahnke, W9JJ, said. “For example, getting the log data into log checking more quickly will allow us to post preliminary results online for nearly all contests.”

Log Submission

Log submission in the “General Rules for All Contests” has been simplified and revised. Individual contest rules will no longer include a log-submission section (with exceptions noted in the contest’s overview section). Here are the most important points.

  • Online log submission: Except for the EME and 10 GHz and Up contests, electronic logs should be submitted through the web app. E-mail log-handling “robots” will continue to operate until they can no longer properly handle the logs without revision. They will then be deactivated and submitters redirected to the web app.
  • Log submission deadline: Effective immediately, except for the 222 MHz and Up Distance Contest (2 weeks) and the EME and 10 GHz and Up Contests (30 days), the log submission deadline for ARRL HF contests will be 5 days from the end of the contest (this includes the IARU HF Championship). For ARRL VHF contests, the log submission deadline will be 10 days from the end of the contest. To accommodate any issues, an extension may be requested, explaining the necessity to the ARRL Contest Branch Manager any time before the submission deadline.
  • Logged frequency: HF contest entries competing for awards as category leaders are encouraged to specify frequency with a 1-kHz resolution. This is standard practice for other top contests, and it assists with log checking.
  • Public logs: The log used for log checking will be posted online for public inspection.
  • Paper logs: These will continue to be accepted, but are only eligible for awards at the discretion of the Contest Branch Manager.
  • Log withdrawal: Logs may be withdrawn up to 10 days following the log submission deadline.

Club Competition

The new toolset for clubs to comply with the Club Competition rules (Section 8 of the General Rules for All ARRL Contests) has been very well received.

Clubs must submit up-to-date eligibility lists before the contest to be included in the results. Only scores from members in a valid eligibility list will be counted toward the club score total. Members must reside and operate in the specified club territory (club circle or section) to contribute scores to a club total. Calculation of club scores will now be based exclusively on this information. No further waivers of eligibility rules will be granted. For more information and tools for submitting your club’s eligibility list, visit the Contest Club Competition — Club Eligibility Changespage.

Log-Checking Penalties

Penalties for “zero-point” contacts, such as US-to-US contacts in ARRL DX, will not be assessed during log checking. Operators may continue to log and submit zero-point contacts. Submitting these contacts helps to ensure that full credit is given and that log checking is as complete as possible.

Remote Entries

Acting as the control operator for a remotely controlled station in the US or its possessions requires that the operator hold a US license and have sufficient privileges for all operation. CEPT/IARP reciprocal operating authority does notinclude remote control of a US station. If another operator acts as the on-site control operator, the entry must be in a multioperator category. The location for the entry will be the location of the station, regardless of where the operator is during the contest.

Operating Rules

  • Multiple in-band CQing: Recognizing that amateur bands are generally full during contests, maintaining two or more frequencies to solicit contacts (i.e., “run”) on the same band and mode is prohibited. (The IARU HF Championship and the ARRL 10 Meter Contest prohibit this practice regardless of mode.)
  • Call sign and ARRL November Sweepstakes exchange: The station’s call sign must be sent as part of the exchange, i.e. “W1AW, number 123, Alpha, W9JJ, 79, Connecticut.”
  • US operators in Canada: The reciprocal operating treaty between the US and Canada requires that the call sign be sent with the Canadian prefix following the call sign, i.e. “W9JJ/VE1,” not “VE1/W9JJ.”
  • Single Operator, FM Only: Cabrillo QSO lines must specify FM as the mode for all FM contacts.

For more information, contact the Contest Branch Manager.

Oklahoma Radio Amateur is First to Score Satellite VUCC from Greenland

Wed, 07/26/2017 - 12:53

It took just 4 days — some of that time without much sleep — but ARRL member Gabe Zeifman, NJ7H/VE6NJH, of Oklahoma City recently became the first radio amateur to earn VUCC — working 100 grid squares — by satellite from Greenland. In fact, his is the first VUCC award of any kind from Greenland. A relatively new licensee, Zeifman, 22, has managed to activate more than 300 grid squares via satellite as well as nearly 20 DXCC entities. Apart from the operating accomplishment, Zeifman told ARRL, he was attempting to inspire newcomers.

 

“I thought it could get more people interested in satellites in general — VUCC is very achievable for anyone — and could also get more people interested in roving,” said Zeifman, who began training this week to become an air traffic controller. “I was overwhelmed by the support I got; it was really astonishing the number of people that helped!” He said one operator activated eight grids for him, while others who don’t typically rove, visited at least one neighboring grid square to give him a new one.

“It was really cool to see our community throughout the world come together to help in this goal,” he said. “I really first envisioned this idea when I realized I had nearly 70 grids confirmed from Iceland, and I thought ‘hmm, OX is an even better location, I bet it’s possible.’”

Zeifman said he prefers the linear-transponder satellites such as FO-29, rather than the FM satellites. He said he may one day get into HF more seriously, but, for now, he finds VHF/UHF/SHF “more fascinating.”

He said the trip to Greenland, Iceland, and the Faroe Islands with his mother and his sister, was “fantastic,” although, he noted, “they may have sometimes been annoyed by my getting up at 3 AM or several times in the night to work passes.” He said Greenland’s weather varied. “Sometimes it was a very nice sunny day, and sometimes it was rainy, windy, and cold,” he recounted. “But, I was happy to operate in everything, and it paid off.”

Zeifman, who said he enjoys visiting in “the north,” has been to Northwest Territories twice in the past couple of years, and is hoping for an ATC assignment in Alaska. “But now that I’m a ham, I’ve really developed a passion for operating satellites while all over the world,” he told ARRL. He said a goal still on the far horizon would be to complete a “reverse DXCC” on satellite — working the US on satellites from 100 DXCC entities. “I think it’s definitely achievable someday,” he added.

Motorola Files Additional Patent Infringement Complaints against Hytera

Tue, 07/25/2017 - 11:26

Motorola Solutions this week ratcheted up its legal battle with competitor Hytera, filing new patent infringement complaints in Germany against both Hytera Communications Corporation Ltd of Shenzhen, China, and Hytera Mobilfunk of Bad Münder, Germany. The latest legal actions, announced on June 24, are in addition to Motorola’s previously filed patent infringement complaints in Germany.

“With these additional patent infringement actions in Germany, Motorola Solutions now has five pending [patent infringement] litigations against Hytera,” Motorola said in a news release. These include complaints filed with the US International Trade Commission and separate patent infringement and trade secret misappropriation complaints filed last March in the US District Court for the Northern District of Illinois.

The complaints filed this week in Germany assert that Hytera’s two-way wireless communication devices with improved squelch functionality infringe on a Motorola Solutions patent. Motorola says the focus of the new cases differs from earlier cases and represents the second patent covering acoustic performance of two-way radio devices.

Already known for its Land Mobile Radio Service products, Hytera entered the Amateur Radio digital mobile radio (DMR) market last year.

In its latest suit, Motorola is seeking seeks an injunction preventing Hytera from offering and delivering products with the acoustic squelch feature in Germany, as well as the recall and destruction of infringing products and various unspecified damages.

Last March Motorola alleged in its US District Court complaint that proprietary and patented information was taken illegally by three former company engineers who now work for Hytera, and that this was done as “part of a deliberate scheme to steal and copy” Motorola’s technology. Motorola contended that its digital radio products were rendering Hytera’s analog systems obsolete, and rather than develop its own digital products, Hytera stole Motorola’s ideas. Motorola said technology features it developed started showing up in Hytera products soon after Hytera began hiring engineers who had left Motorola in 2008, according to the earlier lawsuit.

Hytera offered no immediate comment on the latest court actions by Motorola.

SmartSDR v2.0.17 Now Available

Tue, 07/25/2017 - 08:40

FlexRadio Systems announces the immediate availability of SmartSDR v2.0.17 for the FLEX-6000 Signature Series SDRs.  SmartSDR v2.0.17 is a General Availability (GA) release containing new features and fixes for SmartSDR for Windows, SmartSDR for Maestro, SmartSDR CAT and DAX.

SmartSDR 2.0.17 can be downloaded from the FlexRadio Systems web site. Please download and review the SmartSDR v2.0.17 Release Notes and SmartSDR for Maestro Release Notes prior to installing SmartSDR v2.0.17 to ensure an optimal software installation experience.

SmartSDR v2.0.17 is the first release of SmartSDR v2.  A software license is required to run SmartSDR v2.

All owners of the Limited Edition (LE) FLEX-6700 and FLEX-6500 SDRs or radios sold after May 19, 2017, have been pre-authorized for SmartSDR v2 and do not require the purchase of a SmartSDR v2 license.  To run SmartSDR v2 on all other radios requires the purchase of a software license for the radio.

Obtaining and validating a license for your FLEX-6000 software defined radio is a simple process.  Once the radio and client have network access to the Internet, just load any version of the SmartSDR v2 software on your PC or Maestro.  In the radio chooser, if a radio requires a license, a status message will indicate a license is required before connecting to the radio and updating the firmware.  A “Buy” button is also presented so that you can conveniently purchase a SmartSDRv2 license using our Online Store.  Please see details below regarding purchasing a SmartSDR software license for your radio.

The following highlights are SmartSDR specific features:

Initial Release of SmartLink (Internet remote access) with SmartSDR CAT:   SmartLink is the integrated remote access feature that does not require additional hardware, complicated VPNs or remote desktop software.  Setting up SmartLink is a straightforward process.  Just create a secure user account, log in to the account, associate a radio with your account and establish a remote connection.
 
It is highly recommended that you review the SmartLink Quick Start Guide for SmartSDR and the SmartLink Quick Start Guide for Maestro available on the FlexRadio Systems web site before installing SmartSDR v2.0.17.  More detailed information regarding the operation of SmartLink is available in the SmartSDR Software User’s Guide and the SmartSDR for Maestro Software User Guide.

SmartSDR CAT is also SmartLink enabled, allowing you to use a logger or any other CAT enabled application in a remote setting.  Like SmartSDR for Windows, you will need to login to SmartSDR CAT with your user ID and connect to your SmartLink enabled radio.

Pop Out Panels: The ability to “pop out” or undock panadapters and the CWX and TX sidebar panels is included in SmartSDR v2.0.17.  This new feature allows you to undock panadapters and move them to different locations on your Windows Desktop.  This capability also extends to the CWX and TX sidebar panels as well.  Once undocked, their display position is remembered after SmartSDR is closed and restarted.  Note that there must be at least one panadapter in the main console windows, but subsequently created panadapters can be undocked.

 

(adsbygoogle = window.adsbygoogle || []).push({});

Support for N1MM Spectrum Display Feature: SmartSDR v2.0.17 now provides support for the new Spectrum display feature with integrated spots in N1MM+ (v 1.0.6559 and greater).  For more information on the N1MM+ Spectrum feature, refer to the N1MM website.

Improved Dynamic Range for FLEX-6300: The IMD dynamic range performance of the FLEX-6300 has been improved in this release by a software modification.  This change benefits all FLEX-6300s.

Additional RF Preamp Gain for FLEX-6700 and FLEX-6700R: An additional +10 dB of RF preamp gain has been enabled in the FLEX-6700 and FLEX-6700R.  When operating on higher frequency bands where the antenna is not noise limited (a low noise floor), you can enable up to +40 dB of RF gain.  Please refer to the HelpDesk article How to determine the amount of RF Preamp gain to apply for band conditions for configuring the RF preamp for maximum SNR performance.

New TURFs: New region/entity specific TURF files have been added for IARU Region 2 and Australia (Update #4529 and #4951).

New FlexVSP driver: A new and updated FlexVSP driver (v1.0.6) used with SmartSDR CAT is included in SmartSDR v2.0.17.  The driver installs automatically.  This virtual serial port driver has better performance and stability characteristics than the previous version, especially when used on Windows 10. This updated FlexVSP driver also corrects an existing defect #4394, Serial Ports left “in use” when CAT is shut down. After installing SmartSDR v2.0.17, you will have to manually reset and clear any com ports currently in use by using the HelpDesk procedure Removing “In Use” Com Ports for Available Com Ports

Maestro: X/RIT Readouts Added:   When using XIT or RIT the offset frequency is shown on the display (Feature #4353).

New metering sidebar for Maestro:   A new feature has been added to Maestro that provides a user definable metering side bar that will always show RF Power output, SWR, Mic Level, Compression, and hardware ALC voltage levels.  The new metering side bar is activated by tapping the “Meters>” menu control at the bottom right-hand corner of the screen (Feature #3087).

Corrected Maestro Disconnect Issues:   Multiple disconnect issues have been addressed in SmartSDR v2.0.17, including disconnects related to connection state when using a WiFi  connection, too many clients connections were left in an open state, and client-side out of memory errors  (Defects #4566, #4305, #4428, #4731) 

Maestro: Issue with RF Preamp Not Being Set Properly Resolved:   A defect that prevented the RF preamp form properly setting the RF preamp has been resolved (Defect #4676)

 

SmartSDR for iOS

In addition, SmartSDR for IOS v2 is also available from the Apple App Store.

This update includes several improvements and user requested features.

First of all, this update supports all new features of Version 2 of SmartSDRTM for Windows which includes Remote Access via SmartLinkTM. 

In addition, this update includes:

  • Improved slice touch / moving
  • Option to enable the statusbar (Battery, WiFi Status)
  • Option to reverse the tuning wheel
  • Griffin and CMD Micro: New Commands for Slice and main Mute added
  • Additional user hints in case of wrong settings

Finally, the following bugs were fixed:

  • In DX-Cluster, now six digit GRID QTH Locators are working
  • Griffin Powermate de-bouncing time reduced
  • In Remote Mode, the Tuning Wheel now stays displayed
  • Crash when editing Memories fixed
  • Crash when editing USB Cables
  • DX-Cluster Filter settings are now saved to iCloud

CQ WW Rules 2017 – Update Announcement

Mon, 07/24/2017 - 10:12

The following are updates made to the 2016 rules, effective for the 2017 CQWW SSB and CW weekends.  Full rules will be published soon.  In addition to the updates, the thought process behind each update is included.  We hope this will provide some insight into the reasons for the updates.

  1. Multi-Single definition: The word “transmitter” is updated to “station/signal” and there is now reference made to the FAQ section. This was in response to a post on CQ-Contest made by a member of the contest community.

Reasoning: This further clarifies the definition of MS as was already provided in the FAQ section.

  1. Club definitions. The new rules are shown below.
    • USA Clubs: Participation is limited to club members residing within a 250 mile radius circle from the center of club area.
    • DX Clubs: Participation is limited to club members residing within EITHER the DXCC country where the club is located OR within a 400 km radius circle from the center of club.
    • The word “reside” shall be defined as: To dwell permanently or continuously or to occupy a place as a person’s fixed, permanent, and principal home for legal purposes.

Reasoning:

This language is simplified from prior versions.  Basically, it says that a club member can operate anywhere in the world and still have the score count for the participant’s club.  The word “reside” is also defined.

 

  1. GENERAL RULES FOR ALL ENTRANTS has two additions.

 

  • For ITU Region 1 stations: transmitting on the 40m band, above 7200 KHz during the SSB (phone) contest weekend is not permitted.
  • For ITU Region 1 stations: transmitting below 1810 KHz during the contest weekends is not permitted.

Reasoning:

Interpreting country and ITU rules has consistently been a topic of debate on several forums, including in the CQWW Contest Committee, such as what is a rule versus what is guideline and what about individual country rules.  The CQWW 2017 Rules now remove the option for debate by defining two important frequency limits as part of the rules.

 

  1. Audio Recordings: The updated rule expands the scope from “top three” to “to five.” It also expands the timeframe for such requests from 90 days to 120 days. The Classic Overlay is now also specifically included in the “top five” definition.  Further clarity about the recording now specifies that it must be a continuous recording and that “recordings of individual QSOs” alone in not acceptable.  Finally, the category options to which a log can be reclassified, if no recording is provided, are elaborated and expanded, including the addition of a new category (Administrative Check Log).

 

Reasoning:

The top 3 was expanded to top 5 because, in some cases, a top 3 entrant could be “knocked out” after review.  Since we are still focused on the top 3, even after one was “knocked out,” in order to be fair, the rule was expanded to the top 5.

 

      Equally, with the possibility of a top 3 being “knocked out,” the timeframe for such requests (for a recording) was expanded to 120 days.

      Specifying that the Classic overlay is included in the recording requirement closes a perceived gap in the Rules as they were written.  This was done based on feedback from the contest community.

      At least one “top 3” entrant submitted a recording that was not a continuous recording but instead recorded each individual QSO.  This prevented the committee from hearing how the entrant was tuning the band, something which is essential to proper adjudication.

      In 2016, the committee was faced with a difficult decision about what to do with entrants who did not, or were not able to, submit the required recording.  Disqualification of an entrant for failure to make a recording, in many cases, did not seem appropriate, and some of those were made into a Check Log.  However, such action by the committee then groups the entrant in with those who actually submitted their log as a Check Log.  Therefore, a new category, designed specifically for future top 5 entrants who do not or are not able to submit a recording as required, was created.

      [Editorial comment: It is important to note a few things about the “recording” rule.  First, 2016 was not the first year for this rule.  Second, the committee does not and will not request a recording simply because an entrant is in the top 5.  The committee will request a recording when something suspicious or curious in the log is identified by the committee.  This can be a statistical flag or something identified after human review.  The committee does not request a recording in an attempt to “go fishing” for something “out of the blue” or “without reason.”  If you are not breaking the rules or trying to stretch the rules beyond the letter and/or spirit of the rules, you are probably not going to be asked for a recoding.]

5. Log Checking. The penalty for a call sign copying error (busted/bad call or NIL) is changed from 2:1 back to 3:1.  The penalty for altering the QSO time, for M2 and MS entries, is changed from “remove the QSO” to a penalty of 10x for QSO points and multipliers.

Reasoning:

Historically, the BAD and NIL penalties have, for decades, been 3:1.  The 3:1 penalty dates back into the paper log days, well before the release of the IBM XT home computer.  In 2013, the penalty was changed to 2:1.  The current committee leadership feels that the 3:1 penalty provided more incentive to “get the call right,” and so it is reinstated.

The MS and M2 categories have strict time requirements.  It is possible to alter the time that an individual QSO is logged so that the QSO (or QSOs) no longer results in a band change violation.  In the past, some entrants would have a “small number” of such events, also known as “rubber-clocking.”

Over the years, there has been debate within the committee on how such offenses should be addressed.  Some argued that rubber-clocking is intentional cheating and that even one such violation should result a DQ.  Others argued that it is not “fair” to DQ a log with thousands of QSOs for just one or two falsified contacts.  Both arguments have merit.

However, if the falsified QSOs are simply removed without a penalty, then the entrant has not incurred any harm by cheating; their score is simply returned back to where it should have been.  This means that the entrant has no potential downside impact.  If the committee fails to find the rubber-clocking, the cheaters win.  And if the committee does find the rubber-clocking, then, under the previous rules, the cheaters suffer no injury, because they simply lose the QSO.   So really, they still win.  Risk without possible consequences only encourages risk, in this case, cheating.

Now, with the 10x penalty for rubber clocking in place (for both points and mults), there is a strong incentive for the entrant to not falsify the logged times (rubber-clocking).  If they cheat and get caught twice, they will lose a lot of points and even worse, 20 multipliers (or 40 multipliers if both QSOs were “double mults”).  The idea is to make the penalty for altering logged times so intolerable (high penalty), that the entrants will not be tempted to try.

As has always been the case, excessive rubber-clocking (intentionally subjective) will result in disqualification of the entry along with DQ for all of the operators at that station.

Please note that any band-change-violation which does not involve altering the actual time of the QSO is not impacted by the 10x rule.

Rule changes discussed, but not approved

  1. Combine SO with SOA
  2. Make SOA an overlay category for SO
  3. Allow Self-Spotting of some sort
    • Everyone can self-spot
    • Only assisted entrants can self-spot
    • Assisted entrants can self-spot; Not-Assisted entrants can request to be spotted using the HF contest band where they are operating, in real time.

Arecibo ionosphere HF radio modifcation campaign!

Mon, 07/24/2017 - 09:39

If you are reading this then another radio event of possible interest is the upcoming Arecibo ionosphere HF heating campaign during 24 to 31 July 2017. The new Arecibo ionosphere HF heater nominally transmits 600 kilowatts net power (100 to 200 megawatts effective radiated power) and has a unique Cassegrain dual-array antenna design that increases gain of three crossed dipoles for each band using the signature 1000 ft spherical dish reflector. Read more about the Arecibo HF facility at http://www.naic.edu/~astro/ao50/Arecibo_50th_Paper_Breakall_revised_Oct_23_2013.pdf

During the upcoming campaign, the Arecibo HF transmitter is limited to two frequencies, 5.125 and 8.175 MHz. Campaign HF transmissions will start at approximately 1600 hours UTC and be active approximately 24 hours per day, with some occasional downtime for maintenance and other activities lasting one or more hours. Generally, the 8.175 MHz transmissions will occur in the daytime when foF2 is expected to exceed that value, between approximately 1830 and 2230 hours UTC. Otherwise the HF transmissions will occur at 5.125 MHz. The Arecibo incoherent scatter radar (ISR) will also be active throughout most of the campaign, but since it operates in the UHF band at 430 MHz long distance propagation is not expected.

These transmissions will be in the vertical direction so this is an excellent opportunity to observe NVIS from a powerful transmitter in Puerto Rico. My own experiments are O-mode polarized CW (kicking off the campaign at 1600 hours on 24 July 2017 UTC) for measuring plasma wave and turbulence effects. Experiments by other scientists may use X-mode polarization. To the best of my knowledge, all experiments will be CW with no amplitude or frequency modulation.

Many Special Events Will Be on the Air to Mark the Total Solar Eclipse in August

Fri, 07/21/2017 - 13:33

Radio amateurs from several states will gather in southern Illinois on August 17-21 to operate special event station W9E, leading up to and during the 2017 solar eclipse on August 21. W9E will operate from Marion, Illinois.

“This will be the first total eclipse on American soil since 1991, the first on the mainland United States since 1979 and the first to sweep across the entire country since 1918. It will be an event you do not want to miss!” the W9E announcement said. “The far southern tip of the state of Illinois is the only place viewers can see the totality of the eclipse.”

W9E plans to operate on 80, 40, and 20 meters (and perhaps other bands, if conditions permit), on CW, SSB, and digital modes (JT65, JT9, and PSK31). All amateur operators visiting the area for the eclipse are invited to visit. A copy of your license and photo ID are required to operate. Amateur Radio license testing also will be offered during the event.

While the W9E special event is under way, organizers are planning a joint exercise with ARES® Illinois District 11 Emergency Coordinator W. Bruce Talley, WA9APQ, hoping not only to assist with local communication during the eclipse but to coordinate with other ARES groups as the eclipse travels from northwest to southeast.

“Our plan is to be proactive and ready to respond, as needed,” said Talley. “Local volunteers and those from outside the area are welcome to sign up on the database. We are especially interested if you are coming to the area to view the eclipse and know where you will be stationed.”

Solar Eclipse QSO Party

The Solar Eclipse QSO Party (SEQP), sponsored by HamSCI, will take place on August 21, 1400 to 2200 UTC. As the QST article “The Solar Eclipse QSO Party — Are You Ready?” explains, “The objective…is to flood the airwaves with contacts, all measured by the automated receiver networks of the Reverse Beacon Network, PSKReporter, and WSPRNet. When those observations are combined with the logs from individual stations, the result will be one of the largest ionospheric experiments ever performed.”

Other Total Eclipse Special Events

The South Dakota’s Black Hills Amateur Radio Club in South Dakota plans to operate special event K0E on the day of the eclipse, August 21, 1500-1930 UTC, from Harrison, Nebraska. Operation will be on 20 meters (14.260-14.280 MHz) and on VHF and UHF. Contact Bob Ewing, W0RE, for more information.

SA Sprint Contest – Saturday, July 22nd, 2017

Wed, 07/19/2017 - 23:19

The SA Sprint Contest, is a ham radio competition that aims at improving the operating skills of its participants, and also provide the ground rules for a fun event by preventing stations from parking endlessly on a frequency throughout the operating time. We have based our rules on the long-term and well established NA Sprint. The NA Sprint, according to many people is: “…the most fun you can have in four hours with your clothes on..” N6TR dixit.

 

The SA Sprint is a joint effort of several South American Amateur Radio Clubs and Groups.

 

I – Participants: Licensed amateur radio operators from all over the world.

 

II – Objective: To contact as many participants as possible according to the rules of the contest.

 

III – Entry Categories: There are no single band categories, although if an entrant wants to enter on only one band, that is perfectly fine. Nevertheless the results will be adjudicated according to the following categories:

  1. Single Opeator CW
  2. Single Operator SSB
  3. Single Operator Mixed Mode
  4. Novice
  5. YL
  6. Multi Operator *

 

* Muti Operator stations can have only one transmitted signal at any given time. There are no restrictions to bands/modes changes though.

 

IV – Contest DateSaturday, July 22nd, 2017.

 

V – Bands: 40 and 20 meters:

 

Suggested contest band portions

20 Mts CW: from 14020 KHz to 14075 KHz

20 Mts SSB: from 14120 KHz  to 14190 KHz

40 Mts CW: from  7010 KHz to 7050 KHz

40 Mts SSB: from 7100 KHz to 7200 KHz

 

VI- Contest Time: From 20 to 24 UTC

 

VII – QSO / QSY: Stations must follow QSO/QSY rule.

  1. A station calling CQ, after completing a QSO must QSY ± 1 KHz to answer someone else’s CQ or at least ± 3 KHz to call CQ again.
  2. The station answering to someone else’s CQ, after completing that QSO can call CQ on that frequency and complete one additional QSO, after which the participant must follow the preceding QSO/QSY rule described in point 1 of this section.
  3. There are no limits to the bands/mode changes, however no simultaneous transmitted signals from a station are allowed at all times.

 

VIII – Power: The maximum allowed output power is 100 Watts measured at the output of the last amplifier stage for stations entering Low Power categories. High Power stations: more than 100 Watts output. This apply to both single and multi operator categories.

 

IX – QSO Points: 1 point per each valid QSO. A station can be worked once per band AND mode. Contacts between stations outside of South America are also worth 1 (one) point.

 

X – Multipliers: There will be two types of multipliers.

a) South American prefixes worked. Each prefix counts once regardless of the bands and modes.

b) Different countries worked according to the latest ARRL DXCC List. Each DXCC Country also counts once regardless of the bands and modes.

 

XI – Final Score: Sum of QSO point times the sum of multipliers worked.

Example:    Final score =  100 QSO (100 Points) x  (35 SA Prefixex + 50 Countries) = 100 x 85 = 8500 points.

 

XII – Contest Exchange:

  1.  RS(T) + consecutive serial number starting by 001
  2. The serial number is consecutive regardless of the bands and modes. (One consecutive serial number per station log)

XIII – Valid Contacts: Contacts will be valid if:

  1. Times of QSO match in both logs ( ± 3 minutes)
  2. Frequencies match in both logs ± 1 KHz
  3. The copied callsign matches
  4. The copied RS(T) – matches
  5. The serial number matches
  6. For a station to count towards the QSO total for the contest result it must appear in at least two (2) of the contest logs received by the organizer.

 

XIV – Logs: Contest logs mus include the following information.

  1. UTC time of each QSO in four-digit format, e.g. 2030
  2. Frequency of each qso in four or five digit format depending on the frequency
    1. 7040
    2. 14040
    3. etc.
  3. Complete callsign of each worked QSO
  4. RS(T) sent
  5. Three-digit serial number sent,  e.g. 020
  6. RS(T) received
  7. Three digit serial number received, e.g. 050

Logs format, according to our Cabrillo specification, available at http://sa-sprint.com/cabrillo/

The Cabrillo format for our contest is compatible with the CQ WPX Cabrillo specification, thus, a contest logging softwarte like N1MM, EI5DI, Win-Test, AA-Log, DXLog.net and many others can be used.

FULL Support is provided by the following logging software: See the list here.

N1MM allows for selecting CQ WPX, SSB or CW to start and then change modes. The output will include both SSB and CW QSOs in the right format. We have asked the N1MM team the inclusion of our contest in their supported contest for N1MM+

Revised FCC Form 605 Will Ask Applicants “the Felony Question”

Wed, 07/19/2017 - 22:40

A revised FCC Form 605 — Quick-Form Application for Authorization in the Ship, Aircraft, Amateur, Restricted and Commercial Operator, and General Mobile Radio Services — going into effect in September will ask all applicants to indicate if they have been convicted of or pled guilty to a felony. The FCC used to ask “the felony question” on the old Form 610 and still does on other applications. It’s now expanding it to Form 605, apparently for uniformity. Applicants’ responses and explanations will be used to determine eligibility to be a Commission licensee. The FCC told ARRL that it’s still deciding whether to issue a public notice on the change.

“The Commission is revising the basic qualifications section of the form to include a question regarding whether an application has been convicted of a felony in any state or federal court,” the Office of the FCC Secretary explained in a May filing with the Office of Management and Budget (OMB), which must okay the revision. “Applicants answering YES must provide an explanation regarding the conviction. This item enables the FCC to determine whether an applicant is eligible under sections 310(d) and 308(b) of the Communications Act of 1934, as amended, to hold or have ownership interest in a station license.”

The revision also will apply to NCVEC Form 605 — the unofficial Amateur Radio-specific version of the application that is completed and filed at volunteer examiner coordinator (VEC) examination sessions. VECs will have to start using the revised form on September 7. Responding to VECs’ questions, the FCC offered some guidance, with a particular focus on NCVEC Form 605.

ARRL VEC Manager and NCVEC Vice-Chair Maria Somma, AB1FM, thanked the FCC for honoring a request to amend the effective date of the change, initially in early August. “At the urging of the NCVEC leadership, the FCC took into consideration the undertaking to change and distribute all affected forms and update software and agreed to push back the execution date by 1 month,” she said. The NCVEC will create a revised NCVEC Form 605 and release it to VE teams before September 7.

Once the Form 605 update has been implemented, assuming all other information is correct, negative felony question responses will result in a license grant, the FCC said. A YES will place the application in the “pending file for review” category. Applicants answering YES would have to, within 14 days, provide the FCC with a statement explaining the circumstances, and a statement “giving the reasons why the applicant believes that grant of the application would be in the public interest, notwithstanding the actual or alleged misconduct,” the revised Form 605 instructions state. The FCC said an applicant’s answer to the felony question and explanation will be public via ULS, unless a separate request is made to the FCC that the applicant’s explanation be kept confidential. The FCC will review applications on which the felony question has been answered in the affirmative and decide whether to grant them or designate them for hearing.

“The applicant must provide sufficient information for the FCC to determine whether there exists any material and substantial question of fact regarding whether the applicant has the character qualifications to be a Commission licensee,” the FCC said. There is no set checklist of items, but useful information would include such information as details regarding the conduct that resulted in the conviction or guilty plea, including time and place; the date of the conviction or guilty plea; the penalty imposed and whether it has been satisfied, and “any efforts taken to remedy the wrongs committed and ensure that the applicant will not engage in such conduct in the future,” the FCC said.

The FCC said the only additional information that VECs will have to collect is the response to the felony question; any explanatory exhibits and confidentiality petitions will go directly to the FCC, and VECs will have no information as to the status of such applications.

The FCC said the felony question must be answered every time — even if previously answered — for New, Modification, Renewal/Modification, and Amendment applications. “Assuming that nothing has changed, the attachment to the subsequent applications can simply reference the file number of the application where the complete explanation was given, rather than having to set forth the complete explanation each time,” the FCC memo said. “Clubs are not exempt from the felony question. The question applies to the club as an entity and to the trustee, but not to any other individual officers.”

Individuals convicted of a felony and later pardoned or whose record has been sealed should answer YES, and include information regarding the pardon, “as that will be relevant to whether the conviction still presents any material and substantial question of fact regarding whether the applicant has the character qualifications to be a Commission licensee,” the FCC told VECs. “An overturned conviction need not be disclosed — but a conviction still on appeal must be disclosed.”
