Any reason that you couldn't use rtl_tcp instead? It's pretty common to run rtl_tcp on a remote RPi server, then use a different, local computer to host GQRX. Squelch, frequency changing, and other features should be available via that protocol presently. -- Tom Swartz On Mon, Jan 07, 2019 at 05:01:37PM -0500, Mark Russell wrote:
Good evening - I am trying to make modifications to rtl_fm so that I can change frequencies, gains, modulation types, and squelch values on the fly (and thus avoiding a restart).
Its unclear to me what functions need to be called in order to apply changes to the sdr device so that I can do the above. The rtl_fm code isnt documented so I dont have much to go off of...
GQRX doesnt run reliably on any RPi3's I've tried so I hoping to use a modified rtl_fm in its place. Any help would be appreciated. Thanks :)
