[Elecraft] K2 problems

[wsm at amaonline.com]

Hi

Well I have K2 #5846 with all components in the enclosure, but it's
not doing what I hoped for.

Have been trying to align it and this is what I am getting.
80 meters no receive or output.
40 meters 20 watts out and no receive.
30 meters 10 watts out and very weak receive.
20 meters 1 watt out and no receive.
17 meters no output and no receive.
15 meters no output or receive.
12 meters no output or receive.
10 meters no output or receive.

The output measured with a heathkit meter, which is very close to
being accurate, but not calabrated.
On the first power up before begining alignment I had a very weak
recieive on 15 meters.
The signal source for tuning it is another transceiver with output
set to 5 watts.
At one time I had a good receive signal on 40 meters but lost it in
tuning the other frequencies.
I think the problem is in the receiver, but don't know where to 
start looking. Have checked for cold solder joints several times.
Anyone have any ideas?
Thanks
