[Elecraft] AFSK A RTTY with VOX?

[Richard Ferch]

The answer to your question is yes, certainly. You have to adjust the 
VOX gain high enough so that the LINE IN audio will trigger it, which 
might be different from the level you use with your microphone. With the 
line levels I am using here, I get 4-5 bars of ALC indication with the 
Mic gain control set at LINE 12. With this level of line input, MAIN:VOX 
GN = 007 will reliably trigger VOX in AFSK A for me.

As for PTT control, whatever method is used by HRD will likely work with 
N1MM Logger. The Logger can be configured to do PTT using any of several 
different methods. How are you doing PTT from HRD/DM780?
