RSGB Seeks Regulator’s Records of Complaints about On-Air Behavior

Thu, 10/29/2020 - 09:42

The Radio Society of Great Britain (RSGB) has filed a freedom-of-information request to UK telecommunications regulator Ofcom in an effort to find out how many complaints it has received regarding the on-air behavior of radio amateurs. The RSGB is seeking any complaints filed between January 1, 2015, and December 31, 2019.

“The RSGB receives complaints from time to time regarding incidences of deliberate jamming and foul or inappropriate language on the air,” the RSGB said, noting that its Operating Advisory Service (OAS) provides advice about how to deal with these problems. The RSGB said it wants to hear from radio amateurs who have reported similar problems directly to Ofcom, after following OAS’s advice during the same time.

“The reports should only cover deliberate jamming, use of foul language, or language that would be considered a ‘hate crime,’ as defined by the Crown Prosecution Service/Procurator Fiscal,” the RSGB said. “It is important that you can fully document your complaint to Ofcom with dates, method of complaint, and Ofcom’s response.”

Oldest Known US Radio Amateur, Cliff Kayhart, W4KKP, SK at 109

Thu, 10/29/2020 - 09:36

Charles Clifford “Cliff” Kayhart, W4KKP, of White Rock, South Carolina, died on October 26, a few days past his 109th birthday. An ARRL member, he was the oldest known US radio amateur and possibly the oldest ham in the world.

Last November, Roanoke Division Director Bud Hippisley, W2RU; Vice Director Bill Morine, N2COP, and South Carolina Section Manager Marc Tarplee, N4UFP, jointly presented Kayhart with ARRL’s Centurion Award, which honors centenarian members with at least 40 years of ARRL membership. On that occasion, Hippisley interviewed Kayhart.

First licensed in 1937 as W2LFE in New Jersey, he also held W9GNQ. According to his obituary, Kayhart built his first radio at the age of nine. After working for New York Telephone Company as a young man, he became enamored with engineering, so he headed off to Tri-State University in Indiana, graduating with a degree in aeronautical engineering. Afterward, he went to work for RCA in New Jersey, becoming a quality control manager. Positions followed at Philco Radio and Bendix Aviation.

During World War II, Kayhart joined the US Army Signal Corps, which sent him off to school to study radar. He was assigned to the US Army Air Corps in Georgia and then sent to Hawaii to become part of a Signal Service Battalion. He served at Iwo Jima, shortly after the US victory there, setting up equipment for long-range radio communication and broadcasting, with rhombic antennas in four directions.

In 1946, Kayhart left the Army with the rank of captain, joining Magnavox the following year as its first field engineer; at the time, Magnavox was about to launch a line of television sets. Eventually, he was transferred to the Customer Acceptance Department in Tennessee. Kayhart traveled to Japan in 1963 in search of Japanese television sets. He retired from Magnavox in 1976.

In the 1970s, while living in Tennessee, he spearheaded a project that installed a 2-meter FM repeater on the summit of Camp Creek Bald, still in operation on the Tennessee/North Carolina border.

After Kayhart moved into an assisted living facility in 2017, he had an HF station in his room, courtesy of the Dutch Fork Amateur Radio Group, to which he belonged, and the Columbia Amateur Radio Club. Kayhart remained active on the air until shortly before he died.

According to his obituary, Kayhart was also the oldest surviving Iwo Jima veteran and eighth oldest living US male. He was also the oldest man on the South Carolina Honor Flight trip to Washington, DC. Kayhart was profiled in the June 2018 issue of QST

Radio Amateurs in Western Pennsylvania to Commemorate KDKA Broadcasting Centennial

Wed, 10/28/2020 - 13:13

 

Pittsburgh radio station KDKA will celebrate 100 years of radio broadcasting in November, and Pennsylvania radio amateurs will honor that milestone in a multi-station special event. KDKA dates its broadcasting history to the airing of the Harding-Cox presidential results on November 2, 1920, and the station has been on the air ever since. The special event, which will involve the operation of four stations, will run through the entire month of November.

“More than 100 years ago, many experimenters started delving into a new technology known as wireless, or radio,” said Bob Bastone, WC3O, Radio Officer for the Skyview Radio Society in New Kensington, Pennsylvania. Bastone explained that many of those early pioneers were radio amateurs. “One hundred plus years later, many amateur radio operators are still contributing to wireless technology, while also serving their communities and enhancing international goodwill. Congratulations to KDKA Radio, also known in the early years as amateur radio stations 8XK, 8ZZ, and W8XK.”

Special event stations K3K, K3D, K3A, and W8XK will set up and operate at several locations in Pennsylvania during November. Stations will determine their own modes and schedules. Visit the W8XK profile on QRZ.com for information on certificates and QSLs.

What became KDKA initially began broadcasting in 1916 as amateur radio station 8XK, licensed by the Federal Radio Commission (FRC), the predecessor to the FCC. At the time, amateurs were not prohibited from broadcasting. The small station was operated by Dr. Frank Conrad, who was Westinghouse Electric and Manufacturing Company assistant chief engineer. The transmitter ran 75 W, and the broadcasts gained some popularity in Pittsburgh.

During World War I, amateur radio operation was suspended due to national security concerns. After the war, 8XK was reorganized as a commercial AM radio station, KDKA. The first transmissions of KDKA originated in a makeshift studio on the roof of Westinghouse K Building in East Pittsburgh.

Ham radio clubs participating in the centennial special event include the North Hills Amateur Radio Club in Pittsburgh — which is planning to operate from KDKA’s 1930s’ transmitter site, where an original tower pier still stands. A 1920s’ transmitter site, in Forest Hills, will serve as another operating location. In addition to the North Hills ARC and Skyview Radio Society, other clubs taking part include the Panther Amateur Radio Club, Steel City Amateur Radio Club, the Wireless Association of South Hills, the Butler County Amateur Radio Public Service Group, and the Washington Amateur Communications Radio Club.

Individual radio amateurs will operate from their own stations, and a small group of hams is planning a portable operation from South Park in suburban Pittsburgh.

Stations will invite the public to visit, while observing the required social distancing protocols.

“We amateur radio operators look forward to contacting thousands of other hams around the world to celebrate this huge milestone in the commercial broadcasting industry,” said Bastone. Contact him for more information. — Thanks to ARRL Public Information Officer and Allegheny County ARES Emergency Coordinator Bob Mente, NU3Q, for providing the information for this story.

New Zealand Radio Amateurs Lose Access to 60 Meters

Wed, 10/28/2020 - 06:32

Radio amateurs in New Zealand no longer have access to 60 meters, effective on October 24. Use of the band by radio amateurs in New Zealand is provisional, allowing hams there to use two frequencies in the band — 5353.0 kHz and 5362.0 kHz — as part of a “trial.”

New Zealand Amateur Radio Transmitters (NZART), the national amateur radio organization, said the New Zealand Defence Force (NZDF) advised the organization that it was not willing to approve another renewal of the 5 MHz trial allocation. NZART has indicated that it will continue to work with telecoms regulator RSM to see if other ways may be available to provide access to 5 MHz frequencies by New Zealand amateurs.

As in the US, the federal government and military are primary on the 5 MHz band. According to NZART, the decision was not made lightly by NZDF, but access to that part of the HF spectrum is very important to support NZDF’s new platforms, tactical radio equipment, and updated HF site equipment in the delivery chain.

“Additionally, access to HF is a key part of their communications plans both in New Zealand and to support our forces overseas,” NZART explained. “While this is a disappointing outcome, NZART would like to thank NZDF for allowing us to take part in the trial, and we look forward to working with them in the future on matters of common interest.” — Thanks to Paul Gaskell, G4MWO/The 5 MHz Newsletter

ARRL urges members to strongly oppose FCC’s aplication fees proposal

Wed, 10/28/2020 - 06:26

In a special edition of the ARRL Letter issued October 27 the League is urging its members to oppose the FCC proposal to charge a fee for license applications, renewals and upgrades

The ARRL says:

ARRL will file comments in firm opposition to an FCC proposal to impose a $50 fee on amateur radio license and application fees. With the November 16 comment deadline fast approaching, ARRL urges members to add their voices to ARRL’s by filing opposition comments of their own.

The FCC Notice of Proposed Rulemaking (NPRM) MD Docket 20-270 appeared in the October 15 edition of The Federal Register and sets deadlines of November 16 to comment and November 30 to post reply comments, which are comments on comments already filed. ARRL has prepared a Guide to Filing Comments with the FCC which includes tips for preparing comments and step-by-step filing instructions. File comments on MD Docket 20-270 using the FCC’s Electronic Comment Filing System (ECFS).

Under the proposal, amateur radio licensees would pay a $50 fee for each amateur radio application for new licenses, license renewals, upgrades to existing licenses, and vanity call sign requests. The FCC also has proposed a $50 fee to obtain a printed copy of a license. Excluded are applications for administrative updates, such as changes of address, and annual regulatory fees. Amateur Service licensees have been exempt from application fees for several years.

RF SHARK SHORTWAVE RECEIVER KIT

Tue, 10/27/2020 - 10:12

The receiver works according to the double superhet principle and is designed for the frequency range from 40 kHz to 30 MHz. It is characterized by an elaborate circuit with several quartz-stable oscillators and a DDS frequency processing. In addition, it has a tunable preselector, high-quality ceramic filters in the second IF position and a product detector for SSB and CW reception. For AM, 6 kHz and 9 kHz bandwidth are available. A TCXO ensures high frequency stability of Lokalsozillators.
Thanks to a very detailed, richly illustrated construction manual, it is also possible for beginners without knowledge of HF technology to build this kit successfully.
The adjustment work is limited to the LCD contrast adjustment and the leveling of the S-meter. Required are multimeter, soldering iron, pliers and screwdrivers as well as a steady hand and patience. The only SMD component of the kit is already pre-assembled.

The kit contains all required boards, assemblies and components as well as a machined and printed housing.

TECHNISCHE DATEN

A Snake-like Filament Erupts while a Solar Storm Rages | Space Weather News

Tue, 10/27/2020 - 05:21

This week our Sun continues its upward climb in activity with multiple new bright regions on the Earth-facing disk, including a new sunspot region (region 2778). On top of this we finally had that massive snake-like filament that we first saw in STEREO-A’s view on the far side of the Sun launch as a non-Earth directed solar storm. Plus, we are also in the middle of a solar storm due to the fast wind from the northern coronal hole. This storm, which will likely rage for a few more days before settling down, has already brought aurora down to mid-latitudes, and there is a good chance more is to come! Learn the details of the current storm conditions, see where that snake-like filament launch is headed, watch region 2778 emerge and learn what else our Sun has in store this week.

WX4NHC at the National Hurricane Center will Activate, Other Resources on Alert

Tue, 10/27/2020 - 05:06

In response to Tropical Storm Zeta, WX4NHC at the National Hurricane Center in Miami will activate at 0000 UTC on October 27 (the evening of October 26 in North American time zones) to monitor 14.325 and 7.268 MHZ as well as the VoIP Hurricane Net and other resources. WX4NHC requests surface reports from stations or vessels in the affected area, with or without weather data for use by NHC Forecasters. Reports may be filed using the WX4NHC online Hurricane Report Form.

“The NHC appreciates all the surface reports from the affected area during hurricanes, as they fill in gaps [in] weather data and give [forecasters] a real-time first person perspective of what is actually happening on the ground,” said NHC Assistant Amateur Radio Coordinator Julio Ripoll, WD4R.

As of 2130 UTC, the Hurricane Watch Net (HWN) was in Alert Level 3, Standby Mode. This indicates that the net is keeping an eye on a tropical system or hurricane that could affect its area of interest within the next 48 hours.

As of 1800 UTC, the NHC reported that Tropical Storm Zeta was headed for Mexico’s Yucatan Peninsula. Zeta was some 120 miles southeast of Cozumel, Mexico, with maximum sustained winds of 70 MPH, moving northwest at 10 MPH. The NHC predicts some strengthening before Zeta makes landfall.

Louisiana ARES is set to go on ALERT status at 7 PM CDT, Monday, October 26, transitioning to STANDBY status at a time consistent with conditions. After a request for ACTIVATION has been received from local emergency management officials or served agencies, Emergency Coordinators will activate ARES within their parishes and notify the DEC and SEC. SEC and DECs may activate a Region, if additional human resources are needed to support ECs that have activated at the parish level.

The Louisiana ARES Emergency Net status will be announced at approximately 9 PM CDT, Tuesday, October 27. Frequencies for the Louisiana ARES Emergency Net are 7.255 MHz days, 3.878 MHz nights.

Emergency communications kits from ARRL Headquarters have been pre-positioned in Louisiana in preparation for this event. ARRL Emergency Management Director Paul Stewart, KE5ZW, has contacted ARES leadership in Louisiana, Mississippi, Alabama, and Florida to offer such assistance as HamAid, if needed.

RSGB Radio Communication Handbook

Mon, 10/26/2020 - 11:31

14th Edition

Edited by Mike Browne, G3DIH

This new edition of the RSGB Radio Communication Handbook has as always been updated and re-written so that it remains one of the best guides in the world to amateur radio technology and practice. In 26 chapters, two appendices, 600,000 words on 832 A4 pages it covers the huge breadth of amateur radio
New for this edition is a new chapter devoted to Software Defined Radio (SDR) by the renowned author Andrew Barron, ZL3DW who gives an insight into the types of SDR receivers & transceivers, and how it works compared to conventional radios. There is also a new chapter on QRP (Low Power Operating) giving you an insight into operating on the amateur bands using power levels under 5 watts, which may be ideal for the foundation licensees restricted to 10W. Many other chapters including Propagation, Antenna Basics, ‘Measurements & Test Equipment’ and the ‘Great Outdoors’ have all been significantly updated. Readers will also find chapters on Transmitters and Transceivers both HF and VHF, alongside chapters covering EMC, Basic components, Data modes and even the use of computers in the shack including basic programming of Arduino and Pinguino prototyping platforms. Morse Code is covered, explaining the type of learning methods, decoders, and which type of Morse key you should choose. There is much, much more besides and far more than can be detailed here.

This book provides hundreds of pages packed with the distilled knowledge and experience of acknowledged experts on each topic. First published in 1938 the RSGB Radio Communication Handbook remains a hugely valuable tool that helps you get the very best out of amateur radio.

Corrections and updates

Page 17.8  Helical Antenna

Some time after publication, the author discovered a mistake in his design in that the helical elements are all mounted with the feed point facing towards the centre of the array.  As a result, the phasing of the on-axis radiation from the elements will notionally be 0, 90, 180 and 270 degrees which reduces the overall gain and causes the main beam to squint off-axis.  For maximum on-axis gain, the four elements must radiate in phase which requires all four feed points to have the same orientation, e.g. to the right hand side of the ground plane.

The author analysed the effects of the phasing error in an article published in Amsat Italia News but has not rebuilt the antenna.  The original article has been retained as it shows relevant calculations and useful constructional techniques for similar array designs.  The last paragraph contains the author’s measurements for the array as originally constructed.  The gain of a correctly phased array would be somewhat higher.
