Hey John, Debian Developer, Amateur Radio nerd (K3XEC), and Go team member here.
I use rtlamr. I'm not a very good sponsor right now, but I can step in if no one else has bandwidth; my time is a bit more limited than I'd like, and it'd be cool to have rtlamr in the repos. It'd certainly help save me time too! Give it a few days to see if anyone here has bandwidth, and if not, send me your dsc or git repo for review. On your other points: rtlamr talks to the rtlsdr via rtltcp (rtl_tcp(1)). It's a simple protocol I documented at https://hz.tools/rtl_tcp/ . I've also written a daemon for myself while learning about radio (not released yet; for a few reasons) that will serve a few radios over rtl_tcp; namely, my Ettus B210/B200mini, LimeSDR, RTL-SDR, HackRF, PlutoSDR, an airspyhf, or hilariously, another rtl_tcp endpoint (yo dawg). The hardest part of this exercise (and to be clear; it's straightforward), are two big things: - translating IQ formats; which I've done a bit of documentation on https://k3xec.com/packrat-processing-iq/ including some exemplar files to test with to build confidence in your code - accepting rtl_tcp commands (such as AGC enable, Set Gain) - which don't always translate 1:1. For instance ,some radios don't have automatic gain control, so the command isn't supported; but the client will expect it to be enabled. Other radios (like the HackRF, for instance) have multiple gain stages -- which you can kinda cobble together if you pretend to be a RTL-SDR E4k (https://hz.tools/e4k/) in the rtl_tcp header, and store the IF gain stages in memory, compute the net gain, and scale the gain from min to max -- proxying that into the real radio's gain from min to max. paultag On Wed, Nov 30, 2022 at 6:06 PM John Scott <jsc...@posteo.net> wrote: > Package: wnpp > Severity: wishlist > Owner: John Scott <jsc...@posteo.net> > X-Debbugs-Cc: debian-de...@lists.debian.org, debian-h...@lists.debian.org, > debian...@lists.debian.org > > * Package name : rtlamr > Version : 0.9.1 > Upstream Author : Douglas Hall > * URL : https://github.com/bemasher/rtlamr > * License : AGPLv3 only > Programming Lang: Go > Description : RTL-SDR receiver for smart utility meters > > rtlamr is a program for using an RTL-SDR (and maybe other SDRs?) to > receive readings from smart utility meters.
