I have a birdie at 50.09465 cw normal not rev on a cold k3 and the one at 14.186. The latter being weaker and neither adding to the s meter. My shack has no computers but a wal wart or two so I can confirm those two. Auto notch has no effect.
I believe as Tom mentioned there is a method to remove them or that specific frequency they are on ( not sure which) but I havnt been bothered enough by them yet. 73 Mike R Sent from my spy ring On Jul 6, 2011, at 12:44 PM, Robert Redmon <k5sm....@gmail.com> wrote: > I also have a pretty strong (-120dbm) and annoying 6 meter birdie.
