FreeDV?? (and some other wishes!)

Hi Alan,

I can report that your latest version 2.0.995 seems to have solved the strange and possibly unique  issues I was having with distortion when using virtual cables with previous versions of SparkSDR that prevented FT8 decodes when using WSJT-X.  Of course it may also be that a windows update resolved the issue.

I have just being playing with FreeDV using the FreeDV app as it has the latest RADEV1 mode which does seem to work fairly well.  Can this mode be easily added to SparkSDR?

On the 60m band FreeDV uses upper sideband - Spark seems to use the lower sideband.

A perhaps more versatile option that would be less work for you maintaining all these  different decoders would be to include audio source/sinks as part of Spark, similar to Quisk, so that Virtual Audio cables would not be needed to connect other applications.

Another request would be to add a checkbox somewhere so that all receivers are muted if any is in Tx.

Spark is still my favourite SDR software by quite some distance.  With PureSignal and audio source/sinks built in it would be approaching perfection!

Hope you have a great Christmas and New Year, and many thanks for SparkSDR.
