Thanks, the radio is a Kenwood ts480, so you are right the audio levels can be off as the menu allows a rang from 1-8. I think the norm is "3" .

All audio is handled in the KAM so the Pi only sees serial data decoded by the KAM. Look at your KAM manual to adjust audio levels. You may be swamping the KAM with excess audio from the radio.

John, can alsamixer be used to increase the input audio from KAM plus (using serial/USB connection)? the reason I ask is, on HF i sometimes find my Mark and Space lights are solid from a HF station, however my BPQ software dose not code the data......

No, but make sure you've selected the right audio device in QtSM and that there is sufficient audio drive to trigger the PTT circuit on the SignaLink. Check the audio levels - I use alsamixer.

Thanks Lee and John. I have the Program working well and receiving packet. The only issue im having now is transmit. QtSoundModem is receiving the command from QtTerm TCP, however the signallink is not keying. Is there an extra driver for the signal link?

Brett,

The sudo commands I provided were the "extra's" needed for compiling, but in hindsight you were probably missing the standard prerequisites for running the binary version.

It's all documented nicely here:

Good to know you have it working.? John was right in saying it's easier to just download the binary version and run it, and I should have mentioned that yesterday.

I ran the SUDO command successfully.

I also have the file unzip on the pi.

I issued the "qmake" command and the following is reported...

qmake: could not find a Qt installation of ''

Lee Im not sure what went wrong.......
