Peter, > Saw Bob's transmissions on 166.5 last night at 5:20P on Argo using the > Vert. Just reduce Argo's "Sensitivity," and the screen will clean up. Or turn the Argo AGC off, and set the gain manually. You should see what MY screen looks like with VD, Wm and DPC all running in a 2 Hz BW! Kind of fun to listen to, as well.
