[Elecraft] KPA500 & KAT500 in WPX

[Ken K3IU]

Just thought I'd pass this along in case others may have 
experienced something similar...

Over the weekend in the WPX contest I noticed that I was 
occasionally being replied to as EA3IU rather than K3IU. 
After the first couple of times, I noticed that each time 
that it happened, I had just made a large frequency change 
on a band and the KAT500 had briefly reacted with a small 
change. Thinking about it, if the first element of the K ( 
_._ ) is being  shortened by action of the KAT500, then what 
was being sent would certainly be interpreted as EA( . . _ ) 
rather than K. I'll do some testing with a separate receiver 
(my K2) and see if I can duplicate it. I'll also re-read the 
manual on the KAT500 to see if I can make it less sensitive 
to in-band freq changes. I know that there are changes in 
settings that can be made.
