[Elecraft] two k3's on the same band

[Arie Kleingeld PA3A]

Matt,

At PI4D we have two beams that can work on 20m: a 5L monobander and a 
FB-53 (5L tribander).
The beams are about 75m (220ft) apart. Worst case  scenario(beams 
pointing towards each other):
running 1kW in the monobander we measured a 9W signal on the FB-53.

Yes, you have to take precautions.
We did this once. Solution: when one station is on the air, the other is 
keyed by ptt (shutting down the RX) without possibility
for transmission (disconnecting ptt of the linear amp and the 
microphone- and cw-inputs).
Worked just fine.

73,
Arie PA3A
