[Elecraft] Receiver Damage from another Close Station?

[Pete Smith]

When I set my station up for single-tower SO2R, I was concerned about 
what would happen when I split my tribander stack, and when I operated 
on 40 and 15.  I had bandpass filters but figured that at some time I 
would make an expensive mistake, so I cobbled up a receiver protector.  
Details and a schematic are at 
<http://pvrc.org/~n4zr/Articles/Simple%20Protection%20for%20the%20Fledgling%20SO2R%20Station.pdf>.  
Should cost you only a few bucks.
