[CQ-Contest] Two Radios, one band

[Larry Schimelpfenig]

Steve, a few years ago Phil KT3Y was doing just that, but he was playing with separate antennas that
were well separated from each other. As I recall he was able to listen within 10khz of his transmit 
frequency. I think he finally decided the disadvantages outweighed the advantages. Phil's attempts 
were mostly on cw and I would expect to do this on fone would be toughter.

I would like to tap into the collective wisdom and experience of the
group once again. Is it possible to utilize two radios, one run and one
s&p, on the same band? I was thinking specifically of 15 meters and
wondering if, with the use of stubs or other sort of filtering, one
could isolate a portion of the band, say 21250-21300 for example, for
CQing, while S&Ping the other portions of the band without damaging the
second radio. My particular set up would be using the stacked 5 element
monobanders for CQing while using either the high or low tribander for
S&Ping. The radios are a 950sdx and 950sd. I know that both have
subreceivers and this approach works, but you can't listen to the S&P
frequency while the CQ is going and you are using the same antennas for
both frequencies. The CQ antennas and S&P antennas are 200-300 feet
apart. I appreciate any thoughts or ideas you care to pass along. 73.
Steve, NN4T.
