Hello Rusty, Can you describe what you want to do? For most APRS installations, a single radio is more than enough. I assume this is for VHF APRS but which Kenwood radios are you thinking about? No..

Greetings, I'd like to acquire a radio to use for my 2-way iGate. I've a rack-mount faceplate that can hold another Kenwood mobile, so that would be the preference. Reading

Thank you so very much, Thomas, I could not have hoped for a more thorough and usefully-complete answer.

Hi Rusty, Unix/Linux processes have access to the command-line argument values that were used to start them and various ways to modify those values exist. By default the command "ps" will list the

Greetings, I'm wondering why /usr/bin/screen doesn't appear as a processID, yet /usr/bin/SCREEN does appear but doesn't even exist. direwolf is started via crontab entry as user repeater at boot time,

When I mentioned #2, I was referring to sending text in a packet and each character would mean "another byte".?? So sending something like: ????????? T#001,0.0000003, 1.0000001, 11.25678,

well...finally I found enough time to change some config and I try to implement what is mentioned in the relevant docs. i get traffic from IS and in theory it should be digipeated via the net-kiss.

We see this near the beginning of the APRS Protocol Specification: That makes it sound like the APRS Micro Interface Module (MIM) ( http://www.aprs.org/mic-lite.html ) came first and APRS just copied

I have read in different messages that the Telemetry packet format has been "widened" and n longer limited to 3-digits with no decimal place - in other words 000 - 999. In your document (referenced

The APRS protocol specification ( https://github.com/wb2osz/aprsspec ) can be confusing and difficult to digest. A more gentle introduction can be found in Understanding APRS Packets (

Ray, don't overlook that TXDELAY caters for more than just your tx reaching a ready state, it's not unusual for the rx at the other end to be slow to unmute (if mute must be used), or just slow to

Thanks for the analysis and recommendations. The call W7SID is our Lemhi Amateur Radio Club Call (I'm, KL7UT, the trustee for the Club call). The Radio is an older Synth Yaesu... Don't have the Model

Hello Ray, GUI based APRS tools like YAAC, Xastir, Polaric, etc. are nice as you can see maps, etc. but that's really not a need of an APRS "server" up on a mountain top. Direwolf alone should be more

Finally got around to this. Thanks for your patience. I do have VNC access to the Pi and intend to have the GUI (YAAC I assume) running on it, not on the remote. I Filezilla-ed into the Pi on the mtn

Thanks for the guidance! Life is getting in the way for a few days, but I'll get the .conf file ASAP. Ray D. Congdon - KL7UT [email protected]> wrote:

+1 to what David said. I had a Direwolf installation on a Raspberry Pi 3B that kept disabling the transmit audio whenever the radio keyed up. Turned out that RF was getting into the wiring between the

It's a default setting in systemd to manage system resources. To turn it off: sudo loginctl enable-linger $(whoami) To check the setting for the currently logged-in user: loginctl show-user $(whoami)

Hello Adam, On your first point, yes.. strong RFI can crash all kinds of computers unless they are designed to tolerate it. Both the Zero 2W and the AIOC are just bare boards and even if you put them

I just noticed that the default dw-start.sh includes "screen", so the previous may or may not apply. There are also some distros that kill user processes on logout. It's part of systemd/logind Hope

Hi Adam Generally when you run a SSH remote terminal session the process will be stopped after disconnection. It's called "hup" and disabling is "nohup". There are a few ways around it, but these is
