Re: [Elecraft] Two K2... One Mic... Zéro Problem ? :-)

[Jack Brindle]

This is very close to contesting's SO2R (Single Op, two radios). The  
difference is that in SO2R both radios are always active. When one  
transmits, the other continues to receive. Bandpass filters are used  
to keep the transmit RF from adversely affecting the 2nd radio's  
receiver. If it did hurt it, then that radio would be rather useless  
when the first is transmitting, right?

Switching the microphone between the two radios shouldn't be too  
difficult with a simple switch, and if you really want to get fancy,  
you too could become addicted to creating the ultimate SO2R box... ;-)

A web lookup on SO2R should be quite revealing. After reading the  
articles, you might realize that it is not that difficult to use TWO  
K2s at the same time!
