SV: [Elecraft] K3: birdie on 50.045?

[Lennart Michaëlsson]

I observe the same conditions although the frequency is slightly 
different - probably due to different filter offsets and CW pitch. 
After looking, I see similar "signals" at 50.030 and 50.078 that
change tone with the "shift" control.

In all three cases, the responses are the same with either antenna
or no antenna.  The response drops if the attenuator is engaged.

and for me they are on 50.031, 047, 079 and 095.
I did not look any higher but same patter, they exist only when using sharp filter, in my case 8-pole 400 and 250 Hz.
They are weak and with antenna attached hardly noticeable.
There is also one extremely weak on 1819.0 kHz. Have not checked the other bands
