Hi Dave,
well,
putting the J2 jumper in place on the Signalink has boosted the receive audio. I now see Direwolf report audio levels in the 20s (typically) with the RX knob midrange setting, whereas before jumpering, the levels were typically single numers 3-4.
Putting aside the fact that ALSA doesn't seem to work with the Signalink on Jessie, how do I know what is an appropriate INPUT audio level for use with Direwolf? How do I know when I am saturing the input level? Do I just use Fldigi waterfall to set it? Is the audio input level independent of the receive application?
