[CQ-Contest] SO2R or FD antenna separation dple / vert

[Pete Smith N4ZR]

Igor's probably right, but why take a chance, at least until you have 
tested? One way to be certain is to cobble up a series light bulb 
receiver protector, and put it in the RX OUT/RX IN loop which most rigs 
now have.  Then all you have to do is be sure that RX antenna is 
selected and watch the bulb.  There's an article at 
<http://pvrc.org/~n4zr/Articles/Simple%20Protection%20for%20the%20Fledgling%20SO2R%20Station.pdf> 
that explains how to size the bulb to protect the little-bitty resistors 
in most radios' front-end attenuators.
