James, Sounds like you may have a bad cable. Those two levels should be roughly the same magnitude. Also, if you get audio that changes voltage/volume while doing keydown or Tune, it is not a problem with the software as this puts out a solid tone at a constant level.

He suggested checking the drive audio out on Delta 44 output ports 3/4. I had a chance to do this when I got home from work this evening. It displays the exact characteristics that I hear in the monitor output when the xmitter output goes away (or drops way off). I also had a chance to do voltage measurements on these output ports 3/4 the results of which are as follows Keyed from any source (internal keyer, external key, "key down") Tip (on 3.5mm plug going to SDR) starts at 508 mV and rapidly drops off to 356 mV Ring starts at 76 mV and at the same time as the tip, drops off to 36 mV Using "Tune" holds max indefinitely - 508/76 mV.
