Hi, Steve. Well, the transmitter keyed up and the tone went out on
PSK/Digipan. However, the speech keeps reading "200, 300" etc., no
matter how carefully I tune to the tone.
Also, in either mtty or Digipan, should I adjust the gain? And
unless I'm missing something, can't get the filter to go to 3000.--Matt, N1IBB.
P.S. Haven't felt compelled to either light the fuse on the 480, or
take it to the shooting range.
