[CQ-Contest] RELAY SWITCHING

[Pete Smith N4ZR]

Joe, there is a large family of such things available from China.  I had 
one working to switch my RX antennas.  I coupled the 315MHz RF to the 
inner condfuctor of 300 feet of coax and picked off the "wireless" 
signal at the other end.  It switched fine, but I had trouble with other 
aspects of the setup - losses in the DX coupler for the relay power - 
and eventually scrapped the thing.  The relays may be a bit light for 
transmit antenna switching, but should certainly work to switch other, 
heavier relays.

My experiment is written up in NCJ for May-June 2014

73, Pete N4ZR
