[CQ-Contest] Flex radios

[Mike/W5JR]

I believe nearly all multi op stations, whether M/S, M/2 or M/M, are using some combination of external bandpass filters along to reduce overload along with stubs to knock down harmonic specific signals. Many have gone to high power bandpass filters on the output of amplifiers rather than bandpass filters between the radio and input to an amplifier. 

For the past 3 years, we have utilized a pair of 6300's operating simultaneously in my Yukon as an M/2 Rover during the GA QSO Party. The screwdriver antennas are only 4 feet apart. Each radio is connected to a Dunestar D600 providing sufficient filtering to the 6300 such that neither radio is aware that the other is transmitting. A pair of 6600's will possibly make the Dunestar's unnecessary. We've already been able to eliminate the hardware Winkey and the USB relay board that switched the Dunestar by using new Flex features. 10 straight hours on both Sat & Sun in DXpedition style conditions. 

tnx
