[Elecraft] K3: birdie on 3,721

Fri May 2 17:08:08 EDT 2008

Hello all,

before raising this question to support team I want ask for your 
experience/opinion.
K3/10, 2.7 - 2.1 - 0.4 filters, latest fw

On 80m band I have strong (S5) birdie on 3,721MHz, LSB mode
(testing without ant)
But... when I switch BW from FL2 (2.7) to FL1 (2.1) it completely 
dissapears. Like switched off...
Is it some issue of not so good screw fastening somewhere or is it 
common "problem"?
Any other reports?
Thanks for any ideas...
73!
