K3 Birdies

[n6fb]

I have recently noticed S7 birdies on 7038,10122,14030,21022 and 28045.  Not sure if they always been there, or it is just absense of decent CW signals on the band which make them stand out.  Anybody else have this problem?

I have birdies, just not on those frequencies, and I know what mine are.
  I host the wireless company's neighborhood RAP at the top of my tower
and power it in exchange for free Internet access at the backhaul speed.
  Mine are LO's and clocks in the three radios [1-2.4 and 2-5GHz] up there.

At least some of those (notably 10122 and 14030) are common ethernet
birdies. K9YC has recommendations in
