[Elecraft] [k3] 6m birdies

[Robert Redmon]

I also have a pretty strong (-120dbm) and annoying 6 meter birdie. It is 
when I am in cw mode and moves when I tune, intersecting with the 
passband at 50096 or so . It moves with VFO tuning, but at a much higher 
rate (viewing on the P3). When I have tuned 1 khz higher, it has moved 
almost seven khz higher. It also seems to drift a bit...unlike the 
stationary (internal) birdies that are rather weak and stable. I have 
cleaned up my cabling and tried to make sure all the boards and case 
bits were bonded properly, but those efforts have had no effect. I have 
noticed a similar birdie on 20 meters (ssb) around 14186 or so, but it 
moves opposite the direction of tuning. My efforts seem to have had no 
effect on them (including Sig Rmv). I have been told I will just have to 
live with them, and I can, but it is frustrating nonetheless.
