The reported birdie at 28.276MHz is there, but extremely faint at about
28.275.6MHz on USB and shifts up to about 28.277.7MHz on LSB. I would think
it fair to comment that most ham receivers have birdies somewhere if you
want to try hard enough finding them.
With what I have found on my particular QRP K2 ....

Bob,
~28276 is probably not the same birdie as the image of the KPA100 oscillator
at 18432 at 28264. The closest one I can find depends on having the KIO2
with a 16289 oscillator on board. The oscillator's 4. harmonic is at 65156
kHz. It can be mixed with the 3. harmonic of the VFO, when the input dial is
at IF + VFO = 4915 + (65156+4915)/3 = 28272 which is almost 28276. But if
you don't have the KIO2 then ...
