[Elecraft] K3 RX Antenna & QSK

[Vic Rosenthal 4X6GP/K2VCO]

The Pixel can be connected to your amp key circuit. It turns off the 
power and grounds the antenna on transmit. It works fine with the K3 QSK 
at 30 wpm (haven't really tried it faster). The relay is a little noisy, 
but I wear phones and it doesn't bother me. I am using it about 6m from 
my vertical transmitting antenna with up to 1200 watts, so it is a good 
idea to use this feature.
