ARRL: Jeff Stahl K4BH SE Div Vice-Director Candidate Position Statement

I am running for SE Division Vice-Director because I want to assure that the ARRL members in our division have an opportunity to choose who will represent them in this office. Honesty, integrity, professionalism, and dedication to amateur radio as a service is what I believe should be three characteristics of whoever occupies this office.

The ARRL, as the premier representative of the amateur service in the US, must operate with transparency to its members. Stewardship of the amateur service and representing the interests of ARRL members should be the primary function of the league and its Board of Directors. One area in which the league should take a steadfast stand is in protecting the right of amateur radio operators to install an amateur radio station, including antennas of choice, at the licensed location in their license grants. Because we operate in the public interest and in protection of life and property in times of infrastructure failure organizations with no knowledge of the amateur service and whose only concern is an idealized, narrow-minded fantasy of aesthetics must be subservient to the public service interests of the amateur service and the FCC.

One area on which the league should focus should be attracting younger people into the Amateur Service. Finding ways to cooperate with the public school system to establish radio clubs and use amateur radio in the classroom as a teaching tool should be one goal. School children will willingly learn if they have fun doing it. Reaching into the college and university system is another area where youth can be enticed to become amateur radio licensees. Many colleges and Universities require completion of a project by their senior class, and amateur radio can provide a unique and rewarding outlet for this activity.

One of my goals is to see the ARRL VEC expedite the processing of Amateur Service License grant requests. By using electronic filing methods with the ARRL Headquarters these grants can be delivered to the FCC in a matter of days or even hours as opposed to the week or more currently needed because of the use of the postal service and paper forms. Although some privacy issues exist with electronic filing, the technology currently exists to provide sufficient protection of applicant personal information.

Finally, in the Southeast US we annually go through hurricane season, but our amateur participation in ARES and RACES is far from what it should be. The ARRL needs to spearhead an attitude of service to the public on the part of amateur radio licensees so that the public will always have a line of communications out of any disaster area.

I have been licensed for 49 years and currently serve Broward County as the ARES Emergency Coordinator and the Assistant RACES Officer. I also serve as a VE for both ARRL and Laurel VEC’s and I am the VE team lead for the Gold Coast club. Many times I have presented in front of radio clubs on a variety of topics from practical skills to theoretical topics and personal and psychological subjects. I serve on the board of directors of the Gold Coast Amateur Radio Association, and the Boca Raton Amateur Radio Association. I also serve as an alumni advisor to the FAU Amateur Radio Club.

I hold a Bachelor’s Degree in Electrical Engineering from Purdue University, an Associate’s Degree in Nursing from Broward College, a Bachelor’s Degree in Nursing  from FAU and when I was medically forced to retire I was completing my Master’s Degree in Nursing Informatics at University of Phoenix.

Regardless of who you vote for in this election, please be grateful that you have a choice and can restore this office to its necessary level of professionalism and integrity.

73,

Jeff Stahl, K4BH
ARRL SE Division Vice-Director Candidate

DMR: Update to the AnyTone radios

Here are the instructions for applying the vocoder update to the AnyTone radios.

There is a new Firmware update posted for the AnyTone 878 named vn 1.14. within this update there is an update for the Baseband IC 3258 chip. This update also applies to the AnyTone 868 but has not been published on the 868 update site. The update applies changes to the vocoder and hopefully fixes some issues with coding and decoding of the digital signals. In order to get the update go to the following link CLICK HERE

If you have an 868 only do the baseband update from this file.The rest of the updates do not apply to the 868. You have to unzip the file and save it somewhere on your computer. Go to the baseband update folder and read and follow the instructions carefully to apply the update to the chip.

DMR Repeater and Antenna Installation Status

Summary: The new BRARA DMR Repeater and UHF Antenna were installed on Wednesday, July 31, and is operational for local communications on 442.875 MHz +5 MHz Offset (previous UHF repeater frequencies) with Color Code 1 (CC-1), Time Slot 2 (TS-2), Talk Group 311037 (TG-311037). Connection to Brandmeister is still pending (non-operational).

Details: On Tuesday, June 30, the Motorola SLR5700 DMR Repeater was programmed by Jerry Zaza. The repeater is Brandmeister repeat number 311037 and the local talk group was programed to be 311037. He tested local communication between two handhelds on TS-2 TG-311037, tested the connection to Brandmeister with the Ethernet connection, made sure the repeater would work locally even without an Ethernet connection, and made sure the repeater was broadcasting an analog CW ID every 10 minutes. After testing, which required a low power setting, he set the power setting back to maximum. Robert Eng picked up the DMR repeater and the Ethernet Microwave Antenna from Jerry for installation the next day.

On Wednesday, July 31, at 9:00 AM, Art Lewis, Gerry Gawaldo, and Robert Eng met at the BRARA shack and picked up the new UHF 4-element folded dipole antenna and transported it to the repeater site.

On Wednesday, July 31, at 10:00 AM, the team of Art Lewis, Lewis Lehman, Gerry Gawaldo, Grant Baron, Pablo Solsona, and Robert Eng met at the repeater site at the One Park Place building at the northwest corner of Yamato Road and I-95. The following was performed:

1. The new UHF antenna, tools, and the Microwave antenna were lifted by rope to the roof (top level) of the building. They had to be roped up because it was impossible to bring them up the vertical ladder which leads up to the roof.

2. The old UHF repeater antenna was removed. The mounting nuts were relatively easy to remove (ie they were not frozen).

3. The new UHF antenna was installed in same place as the old antenna using the existing hardware. SWR of new antenna was checked with a Rig Expert AA-600 Antenna Analyzer. SWR was around 1.2. The new antenna was connected to the existing coax cable. The new antenna has a male N connector and the existing cable had a female N connector. Connection was sealed with black tape.

4. The existing Ethernet cable was identified and tested with an Ethernet Cable tester. All 4 pairs and the shield of the cable tested OK.

5. Internet Microwave Antenna was mounted on the bottom of the UHF antenna mask slightly above the edge of the wall around the roof. Ethernet cable was attached. Antenna was leveled and pointed towards FAU.

6. Old UHF antenna and tools were lowered from roof using rope.

7. DMR Repeater was installed in repeater rack. Repeater transmit and receiver ports were hooked to duplexer. The transmit port were both N connectors but the receiver port required a female N to male BNC adapter (repeater receiver port is a female BNC).

8. Ethernet cable from Microwave Antenna was hooked to POE power supply, then cabled to an Ethernet Switch. The LAN1 port of the repeater was also connected to the Ethernet Switch.

9. Repeater was powered on. Gerry Gawaldo had a DMR handheld programmed for CC-1, TS-2, Talk Groups (TG) 1, 2, 9, and 311037. Found that Talk Groups 1, 2, 311037 made the repeater respond (transmit LEDs on front panel of repeater lit) but TG-9 had no response. Do not test actual voice communication because we only had one DMR radio.

Sometime on Wednesday afternoon, it appeared the repeater stopped working. Robert Eng could not get his CS800D at home to handshake with the repeater (getting Call Failed message) and Gerry Gawaldo could not longer contact the repeater with the same radio he used when we tested the repeater after installation.

On Thursday, August 1, at 11:00 AM, Art Lewis, Lewis Lehman, and Robert Eng went back to the repeater site to check the DMR repeater. The red alarm LED was lit, and it obviously had shutdown. Added a right angle adapter to the top of the repeater rack to relieve strain on coax going to antenna. Measured transmit power of DMR repeater – was about 50 watts when keyed up. Measured SWR of antenna plus coax (where coax connects to duplexer) and SWR was 1.3. Tested communication between two DMR handhelds on TG 311037 both near the repeater and outside in parking lot and voice communication works OK.

The Internet connection portion at the repeater site should be complete (other than the antenna aiming may need to be refined). The FAU portion of the Internet connection still needs to be completed in order for the connection to Brandmeister to work.

If I forgot or misstated something, please feel free to correct me. As one gets older, the memory starts to fail.

A million thanks to everyone that helped with this effort to get the DMR repeater up and running. Greatly appreciate your time, effort, and expertise.

DMR: Pi-Star – How to upgrade vn4.1 rc from earlier versions

How to upgrade to the latest vn4.1 rc from earlier versions of Pi-Star. The new version is designed to work on all versions of the RPI boards from a Pi zero up to the latest Pi 4 boards. It became necessary due to the release version of Linux changing and the new features of the new Pi 4 boards.

First you must backup your current pistar configuration. In order to then upgrade you will have to download from the pistar website the latest version ( beta version as of now ) of the software. You will then have to reformat an SD card and then burn the image to the SD card. After that is done copy the backed up configuration zip file to the root directory of the SD card. At this point you can place the SD card into your hotspot and boot it up. It will take several minutes for the hotspot to complete the upgrade and then you will be able to log into it. If you had changed the password from raspberry to something else it will be returned to raspberry as that is one of a few fields that is not saved in a backup. At this point do an SSH login in and do a sudo pistar-upgrade to load that latest upgrades. After that is done do a sudo pistar-update to get the latest updates to the Linux and any pistar binaries that have been updated since the image file was created. Now you can look at the fields on the admin page and the configuration page and make sure any fields you changed but were not backed up are made correct.

Field Day 2019: Visit by Commissioner Weinroth

On June 22 2019, Commissioner Weinroth visited with members of the Boca Raton Amateur Radio Association at their annual Amateur Radio “Field Day” at the West Delray Regional Park as part of the national Amateur Radio Field Day exercise. Field Day is a showcase for how amateur radio (also known has ham radio) works reliably under any conditions from almost any location to create an independent communications network. Since 1933, ham radio operators across North America have established temporary ham radio stations in public locations during Field Day to showcase the science and skill of Amateur Radio.

DMR: Adjusting the offset by Al AF4FA

Most of the boards lately have required adjusting the offset to function properly on DMR. Many boards are shipped with a sticker on the bottom with the required offset.

These are usually pretty close. There is however a way to get this more exact and specific to your radio. Luckily there is a utility built in to Pi Star that enables you to tune your offset.

MMDVMcal
All it requires is pen and paper, a calculator and a little time.

Step one is to gain ssh access to your Pi. The easiest way to do this is go to “Configuration” then click “Expert” then “SSH Access” and log in with pistar and your password.

First, set your radio to 433.000mHz Talk Group 1 and Color Code 1 TS 1.

Next, use the command in SSH to start mmdvmcal “sudo pistar-mmdvmcal” then press “b” to start the BER tuning program.

1.Press the PTT on your radio for about 1 second. Then unkey.
2.If no BER response or a high response press the “F” key to raise the frequency and repeat step 1 until you get the smallest BER you can.

If you get to more than 1.5kc from the starting frequency without seeing a BER response or if the BER keeps increasing press “Q” and start the program over and press “f” instead of “F” and repeat steps 1 and 2 lowering the frequency until you get the smallest BER you can achieve.

At this point you can change the frequency step to a lower increment by using the “Z’ key and entering a lower step (50 or 25 or 10) and go back to step 1 to see how much lower you can get by using the “F” and/or “f” keys.

When you are satisfied with the BER then do the following.

However far off you are from the starting frequency of 433mHz is what your RXOffset should be set to plus or minus.
