Re: Bug#1014017: soundmodem: Fails to build with HID support <linux/hidraw.h>

Dave - I'm an experienced OSS project contributor but am a Debian (-hams) packaging neophyte. How might I contribute to the effort beyond submitting patches? I've read over some of the wiki but there's just a lot of stuff to wade through and I didn't immediately see how one volunteers. I could certainly fix up some of the issues with soundmodem (including referencing the proper upstream repo which is https://gitlab.com/tsailer/soundmodem -- not that Thomas has been merging PRs -- but his code is still there unlike Gna) as well as with aprsdigi for which I am the upstream author.

My ham clubs (WECA.org and W2AEE.columbia.edu) have a number of APRS digipeaters deployed in the greater NYC area (for decades, apparently:-) running aprsdigi with soundmodem and the rest of the Kernel AX.25 stuff. It's really old stuff but it's also extremely stable. My latest rebuild effort is using Raspberry PIs with the DINAH CM108/CM119 GPIO PTT stuff to replace a bunch of old rack-mounted servers that use a USB sound card and serial port PTT.

Looking forward to your advice.

Dave: This patch would be mostly invisible to existing users. It would add the gpio attribute to the soundmodem configuration with a default empty value.

Hi Alan,

I'm part of quite an active packet communtiy (https://ukpacketradio.network/) - DINAH looks like a cool item a number of folks would be itnerested in! Not many of our users are on soundmodem - direwolf, G8BPQ's QtSoundmodem (which I plan to upload to Debian) and (in hardware) NinoTNC are the flavour of the month for us.

I know of a few CM108 mods (our sister communtiy even has a guide - https://wiki.oarc.uk/cm108_sound_interface_smd), so extending functionality to more people would be generally of benefit to all.

Soundmodem is a little old, but it's also not moving very fast so I don't see too much overhead in maintaining a patch for it unless it's likely to degrade the experience for other users?

Cheers

DH

Hey Daniele,

It's been about a year and I've just now gotten around to building a Raspberry Pi connected to a DINAH and can confirm that this PTT patch still works on the latest Raspi Bullseye distro. I don't know if there's any interest in carrying this forward to a committed patch for soundmodem. I can always keep patching it myself if I'm the only one who still thinks soundmodem is a nice small tool for AX.25.

Regarding many more CM108's, I wonder how many of them are integrated such that a spare GPIO pin is used for PTT? Given it's probably not a lot, I wouldn't think removing the device test entirely would be a huge issue. Would you like me to submit a revised PR to do that?
