Re: [Elecraft] Two K2... One Mic... Zéro Problem ? :-)

[Jack Brindle]

If you are really worried about it, Wayne came up with a modification  
to improve the K2's strong-signal handling characteristics. This was  
created specifically to protect the receiver in the presence of  
strong near-by signals. Usually these are only a problem when the  
transmitter and receiver are on the same band, or even on the same  
frequency. If you keep the radios on different bands, I doubt you  
will see much problem.

I hope this helps, et bon chance!
