[Elecraft] KAT3 problem

[Dave Van Wallaghen]

Barry,

I had the same thing here a few weeks ago. I found that I had no output 
from my LPA board. It is now at Elecraft being serviced but I have yet 
to hear the final resolution. It has only been in service for a week or so.

I used a scope and did some signal tracing and found that I had RF on 
the input of the LPA board and a logical HI on the 7T line. But I had no 
output from the LPA itself. I worked with support and we determined that 
something was probably wrong with the board itself. I removed it and 
sent it in.

I found this doing the same thing - tuning up and only had two dashes on 
my display.

Hope this helps.

73,
Dave W8FGU
