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.
