[Elecraft] K3: birdie on 3,721

[Alexandr Kobranov]

Correction and additional info:
I mean switching from FL2 to FL3 as 2.7 is FL1 and 2.1 as FL3

additionaly i found some birdie os 160m band but this was off if I 
switched to higher filter
so with FL4, FL3 there is birdie but with FL2 there is nothing

strange....
what is going on?
