[Elecraft] KPA500 makes birdies on 6 meters

[K7WIA]

I just did a calibration check on the P3 and it was right on using the XG3 at
-107 DBM

with the K3 connected to a dummy load my measured noise floor is -133 DBM (
hard to get close as it is fuzzy)         the strength of the birdies is at
- 125 DBM.  

they seem to have peaks every 140 KHZ  up and down the band,  

 my lowest noise floor in the city  is right at -125 at the best.
so in the city this is not a big thing as you can just detect them if you
know where to look for them.

but I was planing to use the K3 + KPA500 for contesting in rare Grid squares
in remote location out in the boonies, which would be away from city noise,
and I am sure the noise floor would be at least -130 dbm  
then this would be a problem...

maybe they can come up with a fix for it?
