Hello all,
I have returned to using my K2 seriously, and I am curious if
anyone else finds the following on their K2:
When I switch from filter OP 1 on SSB to a narrower filter (i.e through the
variable B/W filter on the main board) I get approx 10 dB loss of signal
strength.
Does this sound right? The S meter reads less, the AF out with AGC off is
less and I am curious if the 5 pole variable bw crystal filter, should be that
much lossier then the fixed 7 pole filter on the SSB board.
I know there maybe MANY reasons, poor crystals, impedance matching issues ( I
do have the NB installed) etc.....but has anyone else seen this much variation
and is there something in particular that I should look at to improve it?
I cannot say that the S+N/N ratio is degraded, but it is annoying that it is
such a difference. I feel I am losing out on gain, when I am listening in
very low B/Ws in CW.
