[Elecraft] K2 hollow sound and low power output

[Don Wilhelm]

Rick,

It sounds to me that once you get over the menu setting situation and 
have all your proper options set into the menu, you should then look at 
the KPA100 wattmeter circuits to discover what the TUNE problems are - 
the resolution of that question may cure other problems.

I am headed for California in the morning to visit with the XYL's family 
and to attend the Elecraft Christmas party. Pardon me if I do not 
respond to requests - this is vacation time for me, and I may or may not 
have my email with me.  I will be back home Dec 21 and handle any 
requests at that time (and also write the bills from the vacation :-( .

73,
Don W3FPR

I think (hope that is!) have fixed it. A bad Anderson connector (internally loose) on the 100 watt side may have contributed to the problem. BUT...

Power output is drastically reduced (10 maybe 20 watts) with a long hello or whistle AND the K2 now has a distinctively hollow sound (same with headphones too). The background noise on an empty frequency sounds as if it is coming from the end of a 10 foot tube. SSB reception is somewhat distorted too.
