GMRS-50X1 – 50 Watt GMRS Mobile Radio from BTECH is Released

QRZ Now - Sat, 05/11/2019 - 2:40pm

A High Power 50 Watt GMRS Mobile Radio from BTECH is Released

BTECH announced today the North American release of the BTECH GMRS-50X1. The GMRS-50X1 follows in similar footsteps and abilities found in our handheld GMRS radio the BTECH GMRS-V1.

 

There was a huge void for users in that, an affordable fully functional GMRS mobile radio has never been available. BTECH took the initiative to engineer that very radio with feedback from the GMRS community. Our mission was to have the simplest  GMRS mobile radio that can easily be used on all GMRS mobile radio channels, while being able to add features not seen on any GMRS radio before! With our team of engineers and designers, along with our BETA users throughout the GMRS community – we were able to accomplish it AND we are able to provide it all while costing less than any other high powered GMRS mobile radio!

More than just a GMRS Mobile Radio

The GMRS-50X1 is a 50 Watt GMRS mobile radio compatible with all brands of FRS and GMRS radios. It is also compatible with GMRS repeaters. Channels are wideband and narrowband compatible. The GMRS-50X1 is also a VHF and UHF scanning receiver capable of adding additional channels for receive only (such as NOAA weather and other channels of interest).

Three Power Levels: Depending on the channel used; you can select from High (50W), Mid (20W), and Low (5W) power settings.

The GMRS-50X1 is compatible with all CTCSS (PL Tone) and DCS (DPL Tones) privacy tones from any other brand of walkie talkies. You can easily scan and select the tone needed to transmit and filter to hear only the conversations you want to hear!

Another innovation, borrowed from our X-Series line, is using ‘Quad Watch’: The GMRS-50X1 operates as multiple radios in one, with a channel selected as the primary channel; while simultaneously watching up to 3 other frequencies or channels. You can simplify the radio to only watch one or two channels as well. The GMRS-50X1 includes dual sync display which allows for displaying both a channel’s name and frequency simultaneously.

We understand the importance of being able to program the radios on the fly. The BTECH mobile radios allow full programmability from tones, bandwidth, settings, and the channel name all without a PC. If you want to go in-depth modifying the radio – PC programmability is still available, allowing advanced tone setting modifications and easy scanner channel imports using CHIRP.

The GMRS-50X1 it also has a standard mono 3.5mm audio out jack to allow easy use with your favorite audio environment.

Channel List Overview

GMRS channels are setup in the standardized FRS/GMRS flow. Channels 1-22 are non-repeater channels coordinating with the GMRS channel list and channels 23-30 are GMRS repeater channels.

Channel List:

  • 15 Modifiable GMRS Two-Way Channels (Channels 1-7 & 15-22) – Receive and Transmit*
  • 8 Modifiable GMRS Repeater Channels (Channels 23-30) – Receive and Transmit
  • 7 Modifiable GMRS Receive Only Channels (Channels 8-14) – Receive Only**
  • 226 Programmable Scanner Channels (Channels 00 & 31-256) – Receive Only

 

* Per FCC GMRS Radio Guidelines; Channels 1-7 are limited to Low Power – 5watt output

**Per FCC GMRS Mobile Radio Guidelines Channels 8-14 transmitting is disabled; they can receive and monitor communications, but GMRS mobile radios cannot transmit on these channels.

 

Pricing and Availability

The GMRS-50X1 is available today. Pricing starts at $179. You can order direct from Amazon or BTECH at: baofengtech.com/gmrs-50×1

May 14 FT4 Mock Contest Session Canceled, New WSJT-X Beta Version Pending

QRZ Now - Thu, 05/09/2019 - 2:04pm

A second hour-long FT4 “practice contest” set for May 14 UTC has been cancelled, following the success of an initial mock contest held on May 9 UTC (the evening of Wednesday, May 8, in continental US time zones). The event followed ARRL RTTY Roundup rules, with everyone working everyone. WSJT-X program suite developer Joe Taylor, K1JT, was among those jumping into the fray. He called the exercise “very useful” and has drawn some preliminary conclusions as to how the FT4 protocol functions in a contest setting.

“FT4 works well, but — as implemented WSJT-X 2.1.0-rc5 — it has some rough spots and performance issues,” Taylor said in a post to the Yahoo WSJT Meteor Scatter and Weak Signal Group. “Many of these have been fixed already during this beta-testing period, and more improvements are still to come.”

Taylor said a second mock contest session using the current -rc5 “release candidate” (beta version) would not be helpful, and it’s not convenient for the developers to build and distribute -rc6 in time for a session early next week, a few days before the Dayton Hamvention. “Instead, we are aiming now to release WSJT-X 2.1.0-rc6 about 2 weeks later — probably in the last week of May or the first week of June,” Taylor said. “Another mock contest practice session will be scheduled soon after that release.” The current -rc5 beta version will expire automatically on June 7.

Taylor said he used a program build that was probably closer to the pending WSJT-X 2.1.0-rc6 beta version than to -rc5. “With my dial set at 7.090 and a 4 kHz displayed spectral window, my waterfall was mostly filled with FT4 signals from well before 0000 UTC to well after 0100,” he said. Taylor managed some 60 stations in 22 states, four Canadian provinces, and in two DXCC entities.

“Generally I found WSJT-X to work well in FT4 contesting mode, but I noted several behavioral oddities that still require attention,” Taylor continued. For example, he said the “TU” message need only be sent once, and if the new station needs to be called again, the leading “TU” should be stripped. He also noted that the “Call 1st” check box becomes unchecked in certain circumstances. “This was intentional, part of an attempt to defeat robo-QSOs; but there may be a better way to address this issue,” he remarked. He said the “Best S+P” button was effective, but feels its behavior can be improved. “Its selection of a ‘best’ caller should favor new multipliers, and perhaps also stronger signals,” he said. “Currently, the button only functions as desired during a reception interval.”

In a post to the Yahoo WSJT Group, Rich Ferch, VE3KI, described the mock contest in one word: “chaotic.” He requested eliminating the “feature” that lets the operator continue to call a CQ-ing station, even after the station has come back to someone else. “At the very least, make it wait until the other QSO is over before calling,” he said.

Before the practice event, Taylor said the developers were “looking for feedback on what works well, what does not, and what an FT4-enabled contest might be like.”

If you took part, post your observations and comments to the Yahoo WSJT Groupreflector, the WSJT Development Group Mailing List, or the RTTYDigital list.

The WSJT-X Development Group reports that it’s aware of several other anomalies in the -rc5 version of WSJT-X 2.1.0. In addition to unexpected program crashes, the program will reset itself to FT8 protocol after the operator accesses the Settings screen. The current build of WSJT-X 2.1.0-rc5 does not run correctly under macOS.

Installation packages for Windows and Linux are on the WSJT-X page. A full release of WSJT-X version 2.1 is targeted for release in July 2019.

One-Hour FT4 Practice Contest Sessions Set for May 9 and May 14 UTC

QRZ Now - Wed, 05/08/2019 - 4:32pm

One-hour FT4 “practice contest” sessions are set for May 9, 0000 – 0100 UTC (Wednesday evening, May 8, in continental US time zones) and May 14, 0000 – 0100 UTC (Monday evening, May 13, in continental US time zones). These events will follow ARRL RTTY Roundup rules. Everyone works everyone. Use a dial frequency of 7.090 MHz (moving higher in 2 kHz increments to avoid manmade interference). Participants must use WSJT-X version 2.1.0-rc5, which is a beta — or “release candidate” — version that contains the FT4 protocol. Installation packages for Windows and Linux are on the WSJT-X page. A full release of WSJT-X version 2.1 is targeted for release in July 2019.

Although still in a beta version that will expire automatically on June 7, the WSJT-Xprogram suite containing FT4 has proved to be popular, and the two operating events are an effort to wring out any additional program anomalies and issues. 

“The scheduled practice sessions are intended to provide shakedown and exercising of the FT4 protocol, the software’s user interface, etc., under something approaching contest-like conditions,” Joe Taylor, K1JT, of the WSJT-X Development Group told ARRL. “We’re looking for feedback on what works well, what does not, and what an FT4-enabled contest might be like.”

Those planning to take part in the FT4 operating events are urged to read The FT4 Protocol for Digital Contesting beforehand. Some set-up will be required.

1) On the Settings | Advanced tab, check the Special operating activity and ARRL RTTY Roundup options. In the field labeled “Exch,” enter the two- or three-letter abbreviation for your state or province (US/Canadian stations) or DX if you are outside the US or Canada.

2) Make sure that 7.090 appears in your dropdown frequency list for FT4 mode. Navigate to File | Settings | Frequencies, right-click on the frequencies table, select Insert, then IARU Region = All, Mode = FT4, and enter Frequency = 7.090.

3) Go to File | Open log directory and rename your ADIF log wsjt_log.adi to something like wsjtx_log.adi.bak, in order to start the mock contest with an empty log. Also select File | Reset Cabrillo log. Restore your original ADIF log after the mock contest(s).

4) Go to File | Reporting and check Log automatically (contesting only) and Clear DX call and grid after logging.

5) Go to File | Settings | Colors and check these boxes (reading top to bottom):

  • My call in message
  • New DXCC
  • New Call on Band
  • CQ in message
  • Transmitted message

6) Do not use a compound or non-standard call sign in this event.

Post your observations and comments to the Yahoo WSJT Group reflector, the WSJT Development Group Mailing List, or the RTTYDigital list.

“To all of the developers and beta testers involved: great job, guys!” said Rory Bowers, K5CKS, on the Yahoo WSJT Group reflector. “FT4 is a masterpiece and promises to be very well enjoyed by DXers everywhere. I think you have exceeded our wildest expectations. I am looking forward to the final release of 2.1!”

Reported Bugs in WSJT-X version 2.1.0-rc5

The WSJT-X Development Group reports that it’s aware of these bugs or anomalies in release candidate 5 of WSJT-X version 2.1.0, no further feedback on any of these issues is necessary.

1) The 64-bit executable for Windows resets the audio input gain to 100% on program startup, when the input audio device is changed, and when switching to a new configuration. A temporary workaround is to, if necessary, reset the Windows audio input to the desired level.

2) WSJT-X version 2.1.0-rc5 does not run correctly under macOS using the current build.

3) Any use of the Settings screen will mistakenly set your operating mode to FT8 when you exit Settings by clicking OK. A temporary workaround is to reselect FT4 from the Mode menu.

4) You may occasionally experience a program crash with the message, “Subprocess error: Subprocess failed with exit code 2,” followed by details that include, “At line 41 of file C:\Users\bill\src\k1jt\wsjtx\lib\ft4\ft4_downsample.f90.” The temporary workaround is to restart the program.

5) If you have configured WSPR mode to use band-hopping, the program may arbitrarily change your band setting in FT4 mode. The temporary workaround is to turn off band-hopping in WSPR mode.

6) Positions of the “OK” and “Cancel” buttons on the Log QSO window move around, seemingly at random. This is intended behavior. Obviously there are some disadvantages, and it may not become permanent.

Some discussion has also involved the choice of 7.047 MHz as the 40-meter FT4 frequency. The frequency is quite close to the W1AW bulletin and code practice frequency, 7.047.5 MHz. It appears that the selection of 7.047 MHz was a late change because of objections to the initial choice. 7.047 MHz is also CW territory, according to the ARRL Band Plan for 40 meters.

Dual-band V-UHF Quad Antennas

QRZ Now - Wed, 05/08/2019 - 8:13am

Why choose the 6BS-270 antenna versus a traditional Yagui?

· Elements of full wavelength, reaching maximum efficiency in TX / RX.
· Optimized design.
· More gain in less boom length than a traditional Yagi.
· Very low noise, which will allow you to improve the reception of low signals in urban environments.
· Extraordinary F/R and F/B.
· Very small turning radius, ideal for small spaces.
· Heavy-Duty construction with high quality materials for extreme durability.

The best directional antenna option for the DX in urban environments, in times when QRM in cities is increasingly high, a closed antenna is the definitive solution to improve DX reception.

Hams Help Trace “Mystery” Signal Disrupting Keyless Entry Devices in Ohio

QRZ Now - Wed, 05/08/2019 - 7:57am

“A recent article in The New York Times reported that many garage door openers and keyless vehicle entry fobs in an Ohio town near Cleveland mysteriously stopped working. While the article invoked The X-Files and hinted initially that a NASA research center somehow could be involved, the cause was not so much mystifying as arcane.

“Garage door repair people, local ham radio enthusiasts, and other volunteer investigators descended on the neighborhood with various meters,” the May 4 article by Heather Murphy recounted. “Everyone agreed that something powerful was interfering with the radio frequency that many fobs rely on, but no one could identify the source.”

More than a dozen residents reported intermittent issues getting their key fobs and garage door openers to operate, and most lived within a few blocks of each other. At one point, the local power utility started shutting off power to areas where the strongest RF signal was detected, but the signal persisted. Dan Dalessandro, WB8ZQH, a TV repairer, was among several hams who investigated. He initially picked up “little blips” on a signal detector, but finally, on one block and at a particular house, the signal was quite loud.

“The source of the problem was a homebrew, battery-operated device designed by a local resident to alert him if someone was upstairs when he was working in his basement,” the Times reported. “It did so by turning off a light.” The individual, who, the article said, has special needs, was not identified for privacy concerns. The inventor, who had no malicious intent, had no inkling that his device was wreaking havoc on the neighborhood until a North Olmstead City Council member and a volunteer knocked on his door. The device operated on 315 MHz, the frequency many keyless-entry devices use under FCC Part 15 rules. The device’s battery was removed, the signal stopped, and all who were involved breathed sighs of relief”
