The K2 makes quite a nice IF rig for VHF transverters, but it has a few quirks,
like most rigs. I've put my solutions to two issues up at
www.qsl.net/ve3sma/downloads.htm .
First is a sequencer which switches the RF to the transverter to prevent it
from transmitting while its internal antenna
Steve,
I did not have success with that link you posted - I got a 404 error.
There is another solution to inhibit CW until a sequencer has completed
and gives a signal back to the K2. It is my article on PTT for CW on my
website www.w3fpr.com. It interrupts the keying unless the "PTT" signal
Add an "l" to the url ;) http://www.qsl.net/ve3sma/downloads.html
I used Don's circuit on my low-band K2 (driving one each
50,144,222,432 XV) and an external sequencer in the Jitney .. the last
step of the sequencer enables TX in the K2. Steve's solution does it
in one board and doesn't require a
My apologies regarding the link...as W1RT correctly figured out there should be
an L at the end of it:

I had seen Don's circuit and decided to go a different route...not having to
dig into the K2 was a plus for me (and I had a good supply of the Omron G5Y

Steve,
The answer to your question involves a discussion about how the K2
handles control of the power output level - in all cases, it tries to
measure the actual power output and the microprocessor controls the
drive level early in the transmit chain to achieve the power output

Actually, Don, it's the other way round. The offending detector is on t
