I would like to get some advice on running two radios on the
*same* band, specifically for 10 meters.There’s plenty of good information here
and
on the web regarding minimizing interference when running multiple radios on
different bands, but not much info at all on the same band.
The plan is to enter the ARRL10m contest, multi-op, mixed
SSB/CW, low-power (<150 watt) category and use a run radio and a multiplier
radio (only one transmitter at a time). To
help minimize interference, one radio would be on CW portion (say below 28.050)
and the other on SSB (above 28.400) and thus maintain at least a 350-400kHz
frequency
separation. Also the antennas for each radio will be different polarizations.
But
given space limitations at the QTH, the antennas can only be separated by 100’.
Are
commercial bandpass filters or homebrew designs available for in-band use?
I’m guessing two
radios have been successfully used for the 10m contest. Any ideas or tips on
the setup for minimizing inter-station interference would be greatly
appreciated.
