Samuel F.B. Morse Sent the First Telegraphic Message May 24, 1844

Wed, 05/24/2017 - 14:32

What was the first telegraph message? Sent by inventor Samuel F.B. Morse on May 24, 1844, over an experimental line from Washington, D.C., to Baltimore, the message said: “What hath God wrought?” Taken from the Bible, Numbers 23:23, and recorded on a paper tape, the phrase had been suggested to Morse by Annie Ellsworth, the young daughter of a friend. The success of the experiment would change forever the national communication system. But Morse wasn’t just interested in the telegraph.

Morse was also well respected for his paintings of people, like the self-portrait on the previous screen and this one of Mrs. David C. De Forest. He painted his subjects with honesty and insight. It was while returning from Europe to take his position as an arts professor at New York University that Morse came up with the idea of a communications system using the electro-magnet and a series of relays through a network of telegraph stations. In order to transmit messages in this system, he invented Morse Code, an alphabet of electronic dots and dashes. The system made communication across the country faster than ever before.

Western Union completed the first transcontinental telegraph line in 1861, dooming the Pony Express, but aiding forces in the Civil War. Mobile telegraph stations, like this one with hastily strung wires, connected scattered military units. President Lincoln kept up with events of the war through frequent dispatches from General George McClellan. One Confederate attack failed when soldiers became tangled up in Union telegraph wires strung from tree stump to tree stump. Morse probably never expected telegraph wires to be a booby-trap!

A generation or two ago, people would send telegrams to announce important news such as a new birth in the family. Ask your family if they have ever sent a telegram.

Introducing Hytera Multi-mode Advanced Radio Voice is still critical, enriched with broadband data

Tue, 05/23/2017 - 08:12

Hytera, a leading global provider of innovative professional mobile radio (PMR) communications solutions, officially launched its highly anticipated LTE-PMR Convergence Solution at Critical Communications World 2017 (CCW 2017), at Asia World-Expo on May 16 in Hong Kong.

Hytera’s LTE-PMR Convergence Solution comprises cutting-edge multi-mode advanced radio terminals, narrowband-broadband infrastructure, and management software. It incorporates feature-rich broadband technologies while ensuring that critically important voice services remain reliably accessible using narrowband technologies such as TETRA, DMR, and PDT. 

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

At the Hytera Global Summit on May 16, on the first day of CCW 2017 before the exhibition opened its show floor, Qingzhou Chen, founder and president of Hytera, invited Hytera’s research and development management team to share Hytera’s insights and solutions with its users, partners, and CCW delegates. 

“During the last 30 years, since I entered the industry as a young man, the two-way radio has seen no fundamental changes,” said Mr. Chen. “But for the last 24 years, Hytera has focused on bringing innovation to users. Now the PMR industry is entering a new era-and Hytera’s LTE-PMR Convergence Solution is the way forward,” said Mr. Chen.

“Our LTE-PMR Convergence Solution marks another milestone for Hytera, and it is a game changer,” said Yelin Jiang, Vice President of Hytera responsible for R&D. “Hytera is once again driving innovation, providing versatile, leading-edge products to users worldwide.” Hytera’s LTE-PMR Convergence Solution allows users to take advantage of a convergent PMR communications solution that couples narrowband voice capabilities with broadband data communications, while offering a smooth migration path to users.

Alongside its new LTE-PMR Convergence Solution, Hytera showcased at its booth a series of narrowband-based innovations, including DMR and TETRA terminals and infrastructure. Hytera’s next-generation Command & Control Centre was highlighted – Hytera demonstrated its increasing integration capabilities, which allow users and partners to develop up-to-date solutions across industries.

FCC Issues Notice of Unlicensed Operation in Public Safety Interference Complaint:

Tue, 05/23/2017 - 07:50

The FCC has issued a Notice of Unlicensed Operation (NUO) to a Texas man for causing interference to a VHF public safety communications system in Dallas County. The FCC Enforcement Bureau issued the Notice to Bradley C. Pike of Dallas on May 17.

On April 3, agents from the FCC’s Dallas Enforcement Bureau Office responded to a complaint from Dallas County Consolidated Services regarding interference to their VHF public safety communications system. Agents confirmed by direction-finding techniques that VHF emissions coming from Pike’s residence were causing the interference. Pike surrendered a radio signal jammer after admitting to agents that he had used the device, the FCC said.

The Communications Act not only prohibits intentional interference, but the manufacture, importation, marketing, sale, or operation of devices designed to jam or disrupt wireless communications deliberately. Pike could face a substantial fine, seizure of radio equipment, and criminal sanctions, including imprisonment, the FCC said.

Pike has 30 days to respond to the Notice, and the Enforcement Bureau “will use all relevant material information before it to determine what, if any, enforcement action is required to ensure your compliance with FCC rules. This will include any information that you disclose in your reply,” the FCC told Pike.

■ A large scale analogue cross meter and 7 segment LED allows for easy reading.

■ Meter has a built-in white LED back lighting allowing for readouts in low level light.

■ Meter has four ranges to measure power from 10W to 10KW. Digital display is not affected when changing measuring range.?

■ Digital display indicates SWR value.

■ PEP power readings with adjustable hold time, while operating SSB/CW.

■ Over-load protection circuit protects your linear amplifier and antennas. User adjustable trigger value of SWR(1.4 ~ 2.5) activates the protection circuit when SWR
exceeds the threshold level. Protection circuit opens the TX GND line between exciter and linear amplifier.

KP-1 Product specification Frequency range 1.8~30MHz Insertion loss Leaa than 0.1 dB Power measurement range 0~10KW Input-and-output impedance 50Ω Electric power range FED 500W /1KW / 5KW / 10KW

Hamvention to boost Greene County economy by multi millions

Fri, 05/19/2017 - 10:47

By XENIA, Ohio (WDTN) – An amateur radio convention is expected to pump millions into the Greene County economy.

The event – known as Hamvention – is being held in Xenia for the first time, this up coming Friday, Saturday, and Sunday.

Kathleen Wright of the Greene County Convention & Visitors Bureau said event organizers are expecting more than 30,000 people to attend Hamvention.

That’s double the population of Xenia.

Wright said the county doesn’t have official figures for economic impact as the event has never been held in Greene County before, but in previous years, Hamvention has contributed millions.

“Hamvention have told us it’s an economic impact of about 14 million,” Wright said.

“Every hotel is filled… At night they’re going to be hitting the restaurants, they’re going to be gassing up their cars, they’re going to be – the people that are campers – they’re going to be out and about all over Xenia. So it’s going to be a big economic impact.”

Wright said hotel rooms in Greene County and in neighboring counties have seen spikes in occupancy.

She said one Xenia hotel sold out within four hours of the announcement that Hamvention is coming to town…..READ FULL ARTICLE

Flex Radio announces The Flex 6400 and 6600 series SDR Radios – Courtesy of Waters & Stanton

Fri, 05/19/2017 - 06:18

Waters & Stanton, the SDR Transceiver pioneer supplier in the UK announced today the launch of the new Flex 6400 and 6600 series radios which will be available in August/September 2017.

 

Orders are being taken now with a deposit payment of just 10% of the purchase price and it is expected that many order will be taken due to the ground-breaking software/hardware combination the new models possess. Some of the major highlights of these new products are listed below:

Modular Design

Both new models (6400/6600) are in a taller case which allows for a modular construction of the radio which in turn will lead to easier and faster servicing due to boards being able to be unplugged and replaced rather than surface-mount reworking being needed to replace faulty components.

Flex ‘M’ series is exactly the same as the flex 6400/6600 with a traditional radio front panel (Flex Maestro style) for those that prefer the look and feel of the ‘classic’ Ham radio. However, as with the existing Flex 6000 models, the Flex ‘M’ can still be used with an additional Flex Maestro in order two operators can use the same radio on different bands at the same time.

Improved Receiver Performance

Despite the fact the existing 6000 series models have excellent receiver performance, Flex Radio have pushed the boundaries once again to nudge performance up a little to ensure they stay right at the top of the pile in terms of receiver performance (Sherwood Engineering independent receiver performance comparison).

Now with 2 SCU’s (Spectral Capture Units) 6600 models only

This is a massive feature which until now has only been available on the flagship model, the Flex 6700. With two SCU’s SO2R (Single Operator, 2 Radios) operation is possible with two operators working 2 bands simultaneously. Most important of all, these operators can use different antenna sockets too. With a single SCU radio, up to 4 slice receivers can be used but only with a second SCU can an additional antenna socket be selected for one or more of the sub-band slices. Single SCU radios will have to operate with all slices on the same antenna socket.

Preselectors Standard on Flex 6400

Preselectors (Band Pass Filters or BPF) were not an option on the flex 6300 (which is now replaced by the 6400 series) and yet not they are a standard option on both the  Flex 6400 and Flex 6400M models

 

Flex 6400 has 4 Slice Receivers

The Flex 6300 had 2 slice receivers as standard and this could not be increased. Anyone wanting up to 4 slices, needed to upgrade to the flex 6500. The flex 6400 has been upgraded to include 4 slice receivers as a standard feature.

Now with DUAL Preselectors! Flex 6600 models only

The 6500 has a single set of preselectors (Band Pass Filters or BPF) which can improve receiver performance on a single band. However, each SCU on the Flex 6600M can be stretched across a 14MHz section of band. If two or more slices where spread across multiple bands, the BPF would have to be switched off which could affect receive performance. Additionally, if using 2 antenna sockets across 2 or more slice receivers, only one of those would be able to have a BPF in place. By adding 2 BPFs, 1 BPF can be used per slice to ensure receiver performance remains uncompromised.

SmartSDR Version 2

While SmartSDR can be used on any Flex 6000 series, it is provided free of charge on the 6600. With ground-breaking single-click remote operation, Flex Radio have taken remote station operation to the next level by providing more users than ever with an easy route in.

FCC MODERNIZES PERSONAL RADIO SERVICES RULES

Thu, 05/18/2017 - 15:49

Media Contact: Cecilia Sulhoff, 202-418-0587 cecilia.sulhoff@fcc.gov

For Immediate Release

FCC MODERNIZES PERSONAL RADIO SERVICES RULES — WASHINGTON, May 18, 2017 – Today, the FCC took steps to update the Personal Radio Services rules, also known as Part 95 of the Commission’s rules, in order to modernize them, remove outdated requirements, and reorganize them to make it easier to find information. Significantly, as part of this effort, the FCC addressed more than two dozen proposals submitted by interested parties. Today’s action will result in a more consistent, clear, and concise set of rules that will better serve the needs of the public.

The FCC Personal Radio Services rules cover a wide variety of wireless devices that are used by the general public. These devices generally use low power levels, communicate over shared radio frequencies, and usually do not require an individual FCC license for each user. Some common examples of Personal Radio Services devices are walkie-talkies; radio control toy cars, boats, and planes; hearing assistance devices; CB radios; medical implant devices; and Personal Locator Beacons. The revisions adopted today reflect a comprehensive reform that will simplify, streamline, and update these rules. These changes will ensure that these rules reflect technological advances, recognize the 21st century uses of the Personal Radio Services, and are easy for the public to use and understand.

Specific reforms adopted in today’s Report and

Order include:  GMRS/FRS Reform: The Commission will increase the number of communications channels for both General Mobile Radio Service (GMRS) and Family Radio Service (FRS), expand digital capabilities to GMRS, and increase the power/range for certain FRS channels to meet consumer demands for longer range communications.

 CB Reform: The Commission will update the Citizens Band (CB) rules, which are decades old and contain outdated requirements that are no longer needed, including labeling requirements and a limit on use of channels when conditions allow long range communications. The Commission will also clarify that hands-free devices can be used with CB radios.

 Overall rule reform: The Commission will remove outdated and unnecessary rules, change other rules to increase clarity and reduce potential confusion, and reorganize and streamline all Part 95 rules to make them easier to understand.

The Commission will also convert rules to plain language format to make them more user-friendly. Action by the Commission May 18, 2017 by Report and Order (FCC 17-57). Chairman Pai, and Commissioners Clyburn and O’Rielly approving and issuing separate statements. WT Docket No. 10-119; RM No. 10762; RM No. 10844 ### Office of Media Relations: (202) 418-0500 TTY: (888) 835-5322

Review of MFJ-1886 Rx-only Antenna

Thu, 05/18/2017 - 09:15

MFJ-1886 Loop Antenna

Dig out previously unreadable signals and track down annoying sources of interference with the MFJ-1886 HF Receive Loop Antenna!

The MFJ-1886 Receive Loop gives you tremendous power to copy weak stations through impossibly strong levels of QRN or QRM. Covering AM broadcast through 30 MHz and beyond, its superbly directive element and bullet-proof low-noise preamplifier dig out buried signals normally lost when using wire antennas. With the MFJ-1886 you get:

[] Perfect loop balance for deep precise nulls
[] Dual-MMIC push-pull pre-amplification for wide dynamic range
[] Indestructible aircraft-grade 36-inch aluminum loop
[] Great portability — weighs only 2-1/2 pounds
[] Mounts using standard TV-style hardware
[] Tough molded weatherproof enclosure for outdoor installation
[] Phantom powered with AC adapter and Bias-T included

Unlike many ADF loops, the MFJ-1886 is weather-sealed, very ruggedly constructed, and mechanically stable under all weather conditions. In fact, you can mount it permanently on any inexpensive TV rotor and direct it from the comfort of your shack. Weighing only 2-1/2 pounds and measuring 36-inches in diameter, it also installs easily on a tripod or handheld mast for portable use.

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

The key to the MFJ-1886`s superior performance is its balanced-input preamplifier. Dual MMICs operating in push-pull deliver an extremely low noise floor along with exceptionally wide dynamic range to handle overload from nearby transmitters. As a result, you enjoy crystal clear reception of weak signals along with bullet-proof immunity from IMD. High-gain amplification and push-pull symmetry provide perfect electrical balance to ensure deep nulls and accurate directivity.

Installing the MFJ-1886 is both fast and simple. Mount it using standard U-bolts on any conventional mast (1-3/4 inch OD or smaller). All mounting hardware is provided. The loop`s preamplifier is phantom-powered through coax, so no external wiring is needed for remote installations. Simply use the MFJ-4117 Bias-T and MFJ-1312D plug-in AC supply that come with the loop, or use any external 12-volt DC source for your portable setups. All you need is a 50-ohm feedline with PL-259 connectors to connect up the loop plus a short PL-259 jumper to connect your radio to the Bias-T. Everything else is included.

With ever-increasing interference from consumer devices and digital systems, amateur-band noise floors are rising and spurious signals seem to appear from nowhere. However, there`s no need to let increased QRN take the joy out of operating. The MFJ-1886 receive loop is a powerful tool that will help you locate those noise sources you can suppress, and null out the ones you can`t!

Maritime Mobile Service Net Relays Distress Call; Crew and Vessel Safe

Wed, 05/17/2017 - 11:38

The Maritime Mobile Service Network (MMSN) recently served as a critical communication link after the sport fishing vessel Free Spirit put out a “mayday” distress call on VHF marine channel 16 after running into trouble in Mexican waters. Brian Stipak, KF7QCX — skipper of the sailing vessel Ubiquity — heard the May 13 mayday, which advised that the Free Spirit was sinking quickly with four people on board and that all were abandoning ship. Unable to raise coastal stations on his vessel’s VHF radio, Stipak went to the MMSN’s 14.300 MHz frequency. Despite marginal band conditions, he was able to relay a position report to net control station Ken Porter, AC0ML, who had assistance from fellow NCS Scott Roberts, KK4ECR.

“They were taking on water and could not find the source, and were deploying their life raft,” Stipak recounted on his website. “He clearly gave the coordinates for his position, which I plotted and saw [he] was about in the middle of the Sea of Cortez, about 46 nautical miles from me. My VHF communication with him was marginal.” Stipak said that while he could barely hear the MMSN net control, the operator was able to copy the information. The S/V Fathom also heard the mayday and set a course for the distressed boat.

Porter notified the US Coast Guard in San Diego to relay the information to the Mexican Navy, which dispatched a vessel to the Free Spirit’s last-known position. The Coast Guard also tried to raise Ubiquity on 14.300 MHz, but band conditions were changing rapidly, and there was no further contact.

Stipak also was able to get through on his cell phone to the port captain at Puerto Escondido and leave information on the distress call.

“We did not hear from the boat in distress for an hour, the last communication saying they were deploying the life raft. I thought the boat had likely sunk,” Stipak said in his website narrative. “Then, the captain of Free Spirit came on the VHF again saying they had found and stopped the leak, were trying to pump out the boat, could not start the engine, had deployed the life raft, but not abandoned the boat and did not yet want to cancel the mayday.

Roberts later learned via the Coast Guard that the Free Spirit had been towed to the port of San Carlos and that all on board were safe.

“It looks like a great resolution to a very intense situation,” Stipak allowed afterward.

The MMSN is in its 50th year of operation. — Thanks to Jeff Savasta, KB4JKL, MMSN assistant net manager
