[CQ-Contest] MO2R?

[Igor Sokolov]

What Scott describes below is almost exactly and in full realized in the 
hardware of  Expert-1kW Italian transistor amplifier 
http://www.radio-ham.eu/Expert1K-FA.htm
The only difference is that Rig#2 has no priority. Both rigs are working on 
firs come first served basis. It is sort of entry level M/S. I just thought 
it might be interested for some who wants to try it. Multy op categories are 
IMHO much more fun then SO. The thrill is multiplied by the number of good 
ops working in sync.
