[Elecraft] K3 JT 65-HF transmit?

[Edward R Cole]

Be sure your K3 is in DATA-A mode and not SSB.  I lost a bit of time 
the other night trying to find out why I had no modulation in JT65 
when I noted I was on a freq. set to SSB.  Switched to DATA-A and the 
modulation just popped up.  I use straight audio in/out from my K3 
and direct RS232 control of PTT.  I use a emu0202 external soundcard 
which makes manual setting of Tx audio simple (just twist a 
knob).  Set meter to read ALC and adjust Tx audio so four bars are 
steady with fifth bar flickering with modulation.
