[Elecraft] K2 - LOW SENSITIVITY ON 30 AND 17 METERS

[Chris Page]

I am puzzled as to why my K2/100 has lost most of its sensitivity on 
17 and 30m.

It is the K2/100 I use at my Florida QTH and when I returned from a 
visit of a few months to the UK, I found it has lost most of its 
sensitivity on 17 and 20m.  I can only hear very strong signals and 
they sound very weak.  The other bands are fine and it transmits ok 
on all bands, including 30 and 17m.

I have tried tweaking L8 and L9 and C21 and C23 (30m) and C32 and C34 
(17m) but this has not made any difference.

I cannot find any other part(s) of the K2/100 circuit that only 
affect 17 and 30m on receive.

I have researched the Reflector archives in the hope of finding 
someone with a similar problem, without success.

Any help and suggestions will be appreciated, please.

Thanks and 73 de Chris, N4CJ (G4BUE)
