KA9Q Server cmd options pcmcat #888

Closed papasven closed 2 weeks ago

papasven commented 2 weeks ago

Hi

I'm currently trying testing branch with ka9q way. There is a problem with pcmcat command line options here in ka9q.py. With "-2" it doesn't work, without is ok.

    # pcmcat -2 -s 404090000 sonde-pcm.local
    _cmd = (
        f"pcmcat -2 "
        f"-s {int(frequency)} "
        f"{_pcm_host} |"
    )
pcmcat -V

I expected this would probably happen, with @ka9q doing lots of of development on ka9q-radio, it was likely that my initial support would break at some point.

I'll talk to Phil and find out what the current correct approach is and try and test.

When support is finally 'released', I'm probably going to have to recommend users check-out and compile a particular commit to avoid this kind of thing happening.

Ok, would like to remove the spy server someday. ;) First manual tests with KA9Q worked very well, the pc is no longer sweating.

Indeed! The performance increase is quite significant, and I would like to move away from spyserver at all of my sites also. However I'm still waiting for spectrum output support from @ka9q before I can complete this... For now it's just fixed frequencies...

I've fixed the issue with the -2 option in the testing branch now. I've also made some updates to the setup notes since some additional dependencies are required for the latest commit of ka9q-radio.
