Have heard a few stations on 20m, no one hears me so far.  

I am using the Hermes Lite 2 SDR with 5 watts, and the Quisk application.

I have tried using the 'freedv' application, but I haven't been able to make it work with Quisk.

Meaning, Quisk has both built-in FreeDV, and can use any digital mode such as 'freedv' or 'wsjtx', via Pulse.

Quisk exports its own Pulse sources and sinks, but 'freedv' doesn't seem to find them.

Also, 'freedv' does not show up in the list of applications in 'pavucontrol' so I can't use 'pavucontrol' to point 'freedv' at the right sources/sinks.

I may try later to get on using a different radio, but have other things to do.

I use the HL2 with Quisk occasionally. A few things:

1. Have you built the FreeDV application using the "pulseaudio" option to (./ pulseaudio)? On Linux, at least, PulseAudio/pipewire support tends to work better than PortAudio.
2. For Quisk, using the "Hamlib NET rigctl" radio and "localhost:4575" for serial port/hostname works for PTT.

Thanks, Mooneer.  I think I've seen you on the HL2 email list...

I was able to get a few callbacks on 20m so Quisk's built-in FreeDV was working OK.

I was using whatever copy of freedv came on Debian 11  (bullseye) on an Intel PC.

Now I'm building from source as you say with the pulseaudio flag so hopefully that works better.

Building freedv from source is a big win... Source version is 1.8.2, repo version is 1.4.3, repo version is well out of date. New version seems to handle pulseaudio correctly, but now no one is on the air any more so I can't be sure.  I suppose later I can transmit to a dummy load with one HL2 and receive with the other, but for now my play time is over for today....

Where are you located?


Maybe we can find someone closer to you to turn the beam your way.

Hi all,

There's always my "listener" that WILL send back a reply if it finds // in your Txt Msg
and hears you over the HFC cable switchmode hash that wanders the 40m band.

7177KHz LSB mode 700D

And If you login to the WebSDR at:

This can decode 700D either USB or LSB, most HF bands.
and send back your audio and support about five users.
(all on the same band)

Keep smiling

(We will eventually get Digital Voice recognised)
