Anyone using a K2 for RX and another TX?

[info4mjs]

Hi,

I was wondering if anyone is using the K2 just for the receiver and using some other transmitter with it in a transceive mode.  Most of us probably (had or ) still have one of the big 4 name transceivers and I was thinking about using the K2 in conjunction with another radio to take advantage of the 100W power or AM mode.

Your thoughts are appreciated.

Thanks in advance.

yes yes yes.......

Hi Mike,
at this VERY moment I am using my k2/100 with my icom 756pro trying to get
the VU4.. ( rare dx)...

the K2 noise blanker helps me more decipher the esp weak signals from the
VU4 on 20 meters. I have not established a very decent way to mute the k2
when transmitting....other than use the K2 second receive antenna input
( on the k160rx) and transmit into a dummy load at the same time as I let
loose the KW on the 756....into a different antenna.
The other missing element is that I cannot receive on my better antenna as
it is
150 feet closer to the offending power line poles !!!! So I am transmitting
with the big  beam and listening on my old classic 33 with the K2.

I have fitted my 756 pro with a tap just after the t/r relays, so I an
share the antenna selected, however as I mentioned I can't even use that
function, since that antenna is different for each rig !!!

now just waiting for propagation to open up in the midwest RF BLACK HOLE.

I briefly tried to use the test mode to disengage the TX , but that seems
to function in cw only. Better ideas are welcomed....

        Just for fun I whipped up a little logic circuit which placed appropriately
in the K2 and with an added DOW-KEY relay and a foot switch would allow the
use of the K2 as a reciever with a free standing transmitter. This is
untested and just a mental exercise but it is how I would attempt to resolve
the problem. I believe you can do it without breaking a single trace. It
ain't QSK but it is just one switch.

e-mail me if you want the proposed circuit.

        WARNING: If you play around with the MCU "|MUTE" circuitry, it is very ESD
sensitive and I am not the only one who has discoverd that. The only
solution if you blow it is a new MCU if you want the audio mute.
