So I have configured the IGATE servers and logged in. I would now like to beacon over the iGate port if it is connected over internet. Since I am moving PBEACON does not seem like it would work. So how does one do this? -- 73, AB1PH Don Rolph

Hi Finally my cable for the digirig cable has shown up and I have installed it. I am changing the cable from the kenwood cable so that I can use the diigirig unit. As some of you already are aware, I previously was using audio usb cable for receive and ptt from the cat connector on the kenwood. I am hoping to change that to work with the digrig mobile. It is working fine for receive but I cannot send ptt. I am using one cable from the audio to the 6 pin connector on the d710G. Apparently there are settings so that ptt can be asserted through the same cable. Can someone please help me with the settings or direct me where to find the information. The radio works perfectly on receive. Thanks as always and please ask any questions. Joe VA3TV

When configuring an object with OBEACON, is there a way to configure it so time is sent other than *010000zH possibly local time ? I can make the object, and it is sent properly, but I guess I don't understand the time thing. Thanks Arnold, KQ6DI

I don't have a build of direwolf in front of me now, but the question is simple: can I use tactical calls like SAG01, SAG02, EAGLE, DOG, MTNTOP, etc., essentially any combo of 6 characters, so long as I have a legal callsign in a beacon that is transmitted no more than every 10 minutes?

Hello, successfully built Direwolf on a Linux machine. Now I would like to distribute the compiled version to other club members. Rebuilding from source on the other devices is out of question: we use reflashed chromebooks for field activities, not intended to have complete build stack installed. I noticed there is directory 'debian' which includes files resembling package configuration, but apparently not to be used as-is. I miss any documentation as to how to build .deb package. Can you help please? Thank you Jindra OK4RM

Silly question. Is there an icon for Direwolf that can be used for the shortcut on the main screen? Or did I just create the shortcut wrong? I thought there was one at one time. Arnold, KQ6DI

Apologize if all I need is a pointer to read the docs, but.... I have a telemetry application that normally talks KISS to direwolf and it sends out via the radio. My understanding is that if I want to send out via iGate, I would do that via my KISS program and direwolf would just send to whichever I choose. Is there a way to configure things so that if the packet fails sending to one of the iGate servers I have listed (like my starlink is down) it will automatically route start using the radio?

As requested. I've been running RTLSDR_Airband from the day I found out about it. I was trying to write code for a multi-channel FM receiver and it was proving quite difficult, and I dropped the effort once I found out about it. It uses a very efficient algorithm mix and filter multiple frequencies to baseband RF, where AM and FM demodulation can be applied. FM demodulation is very efficient as well. On my Raspberry Pi I'm running 10 channels at present, with 4 recording audio from repeater outputs, 4 recording baseband RF from repeater inputs, and 2 FM audio channels piped into Direwolf. This consumes about 10% of one of the 4 processor cores on a Raspberry Pi 4. It is supposed to work on a Raspberry Pi 2 and Pi 3, using the on-board GPU to accelerate computation, but I've never tried it. It is also quite reliable, and I've had it running over a month at a time on the Pi. The reason I was doing this was to hunt a repeater jammer in the area, and APRS was an afterthought. The jammer is now gone but new ones come from time to time so I record 4 repeaters 24 hours/day. The audio recordings are used for evidence, and the IQ recordings for analysis, especially experimentally with transmitter profiling. Experience using Direwolf made it obvious it would be a good fit - and it almost was. I now have about 40 GB of recordings. I also encouraged some fellow club members to run similar setups and devised a method by which they could upload their recordings to my system, making them all available for review or analysis. It still has some rough edges but basically works. The most difficult thing is managing security. I called the system Dragnet, which if you look at the files you'll see this as the user account for the programs. The biggest issue I had, which I was dealing with today, was that Airband emits 32-bit floating point samples and Direwolf wants 8 bit unsigned or 16 bit signed integers. There are programs that would do the conversion but they are rather complex, so I decided to write one for the purpose to act as an intermediary between Airband and Direwolf. Initially I tried reading from Airband using an Internet socket, and writing to a socket for Direwolf to read but I ran into difficulties and just wrote the output to stdout and piped it into Direwolf. That worked well for APRS traffic on 144.390 and a couple of weeks ago I added the ISS APRS RS0ISS as a second channel. Yesterday I checked the logs and found that I was receiving the ISS about once per day with several transmissions during the pass and was pleased. I started thinking that because I had two instances of Direwolf I would have 2 igate connections and thought that wasteful, so I decided to pursue the socket to socket sample format conversion again. This time I used Microsoft Copilot which sped things up a lot. The last thing I asked Copilot to do was add GPL V3 terms and conditions to make the code open source. After much back and forth I now have a version which will forward samples to another socket or to stdin based on the command line options. I wrote simple system services for airband, the two instances of the format converter (Terrestrial and ISS APRS) and one instance of Direwolf. It's all running nicely as I write. The main components are Configuration files for airband and Direwolf Systemctl .service files for the 4 system services. The sample converter code, which I called f32_i16.c due to lack of imagination (maybe I should call it AirWolf) I'm happy to share all of it and will post some stuff in the replies. Use at your own risk of course.

Compilation is: gcc f32_i16.c -o f32_i16 -lm You can find the code at https://github.com/SullivanChrisJ/AirWolf.git I run it as a system service with the following .service file (installed in /etc/systemd/system, with $ sudo systemctl enable --now f32_i16_1.service. One of these is needed for each of the channels. Service file would be something like. It could probably be improved.

I've been using RTLSDR_Airband with Direwolf for APRS for some time now. Originally I tried converting the socket output from Airband from f32 to i16 and sending the output to another socket for Direwolf to read, but couldn't get it to work. I abandoned that idea and sent the converted output to stdout instead and it worked perfectly. Recently though, I added the ISS to my receive list in Airband, and that worked nicely as well, and I pick it up every day or so. I I though it would be nice to use 1 Direwolf instance to handle both APRS sources, so I have resumed work on socket output from the conversion program and socket input to Direwolf. I now have it to the point where the Direwolf opens the socket successfully and says it is listening. The problem is no decodes. However, if I listen to the socket with netcat and pipe the output to Direwolf stdin, it works. This uses 7358 as the output port from the converter. When I run Direwolf like this: direwolf -a 10 -r 16000 -n 1 -b 16 -B1200 -t 0 UDP:7358 I get.

I have an RTL-SDR receiver I use for monitoring ACARS, and APRS. I am interested in monitoring just for fun other signals on the uhf/vhf bands. I have an OMNI X scanner antenna up pretty high so I get decent reception. I live close to a large metropolitan area. There is an industrial area where there are ships and barges. APRS is kind of boring, but ACARS is interesting. I have used in the past my dongle with DSD plus and SDR Trunk for monitoring the state communication system. DSD Plus is too unwieldy to use. But I like SDR Trunk. Anyway what other entities are possible to configure to listen to? i use MX Linux.

Does anyone know if it is possible to add a JSON Post output to Direwolf. In addition to saving the GPS data to a logfile I would like to also send the data to a website. The preferred delivery to the website is JSON POST. Jakob

Hello again to the group! I start Direwolf via cron with dw-start.sh. I’d like to add -dgt to the startup command. My question is, which line (number) do I add -dgt to? Thanks in advance for any replies. Doug AE9DM

Where is ISOTIME derived from in the Direwolf logfile? Is this time info received from APRS messages or is it a timestamp added to the log derived from the local time on the PC running Direwolf?

Hello, I get the the error "Timeout waiting for input from audio device 0. Terminating after audio input failure." immediately upon transmitting a connection request to a pbbs. The FTM-500 locks up in transmit, and I need to disconnect the digirig cable from the laptop and restart Direwolf/Paracon to recover. Yes, it looks like RFI, but this hardware combination works fine with VaraFM and Soundmodem. I've also added additional ferrite beads to the digirig cable. I've noticed that I don't get the same error (and transmit lockup) when I set the audio output device to a different soundcard, while keeping the audio input on the digirig lite. I am able to transmit on the digirig lite without lockup. Direwolf also works fine while just listening on 144.39. The audio levels look good and most packets are decoded. Any help will be appreciated!

Hi, I am trying to set up an IGat. Everything seems to be working. Packets are being decoded. The connection to the gate servers is the only thing that isn't working. Connect to IGate server noam.aprs2.net (192.104.234.219) failed. It's been running for a couple of hours now and has tried half a dozen IP addresses so far. I've got a good internet connection and can ping those servers. One thing that I am not too sure about is the APRS-IS password. Should I get a password for my call sign or should my call sign be appended with the SSID? Aside from the password, everything else seems fine in the config file. Any help or tips would be appreciated. Sepehr N6IRN
