[Elecraft] Pair of K3 in master-slave mode

[Igor Sokolov]

I wonder if somebody knows of an easy way to make a pair of K3 (both 
with subRX) work in master-slave mode. In other words I want to tune one 
K3 and want the second K3 follow. The idea is to have 4 antennas 
connected to 4 receivers so that 4 directions can be monitored 
simultaneously in contests so polling from a contest logger is also in 
the mix. If possible, a hardware solution would be the best but software 
solution is also OK.
