Topband: Receive ant question

[Jon Zaimes AA1K]

for the years I used a TS-940S, which was prone to picking up RF on a 
Beverage plugged into the RX-only input, I used a simple $2.00 Radio 
Shack SPST reed relay to short out the coax at the back of the radio, 
through a 47-ohm resistor to ground. this solved the RF problems. the 
940 was one of the first radios to produce a key-timed 12vdc output so 
this made it easy to power the relay. most newer radios have similar 12v 
keyed outputs (and many have improved RF protection).
