[Elecraft] K3 - IF out - fixed - BUT

[Don Wilhelm]

Jim,

You are correct that the K3 IF output should/will change frequency when 
the K3 VFO is tuned.  The signal at the IF output jack will be 
essentially RF input frequency minus the VFO frequency (except for 6 
meters where it is 'plus').

If you are trying to "tune" with only the Rocky software and no K3 
control application to change the VFO on the K3, then K3 IF will remain 
unchanged.  In other words, you need some more software to do that task.

WRONG.  It stays put and I very quickly tune completely off of the display.
