[Test-Equipment] PTS 040 Freq. Synthesizer.

[RJ Mattson]

Hi Craig
My thought is to use the PTS for frequency control of my cw HF transmitter.
 I would need complete PTS signal cut-off between morse charactors (QSK) and 
on receive mode.

If pin #42 has to go low to activate the remote level (pin #22) then, would 
I also lose front control of frequency?

Some other options seem to be:
1. - Just keying pin #42  (remote - local control)? What is the output 
frequency with all remote freq control pins hi and #42 lo?
2. - Tapping the existing local RF level pot on the front panel?
3. - ?
All ideas welcome.
