[Elecraft] Sunspots and the K2, K1

[Louandzip]

I built my K2 and then a K1 during the solar maximum in 2001/2.  One of the hallmarks of the K2 is it strong signal rejection.  It was one of the best radios of the time and is still among the better radios today.  The K1 isn't really in the same league, but it's no slouch either.  The worst test I put it to was operating in CH on 40m during a contest weekend during a business trip.  Huge wall to wall signals but I was able to participate fine.
Somebody mentioned switching in the K1's attenuator.  Originally, doing so created a loud audio pop.  I came up with a mod to eliminate this, adding a RFC across the contacts of the relay K1 (coincidentally) which was adopted as part of the design.  

I grinned when I saw Wayne N6KR's terse response.  He's still justifiable proud and protective of his babies.
