[Elecraft] K3 - Minor question

[Carl Clawson]

Fred, did you happen to tune across a frequency where you had earlier
removed a birdie with SIG RMV? That causes the passband to jog a bit and you
can hear it in the sound of the noise, especially at narrow bandwidths. Tune
across it again slowly and watch the P3 carefully. Sometimes you can see the
birdie come flying across the P3 at you and "tunnel" through your passband.
It's pretty cool when you see it.

73, Carl WS7L
