Also, while dialing in the L and C values, tap ANT to switch between

Ok, my final conclusion (i promise)
Manually adjusting the L and C values of the ATU DOES have an effect
on BCB reception (had my RF gain turned down before, so seemed like
there was no difference). Maximum L (17.35 pH) gives maximum received
signal strength on a short antenna, as expected.
Ok, Chuck, thanks alot. That explains all. I was thinking it was a pi
with two capacitors.
So anyway, for BCB reception, the capacitor doesn't do much and you
would pretty much want to have maximum L, right?

As for the hoped for multi-bandwidth filter, I guess it is probably
I'm wondering what minimum complement of filters would work for me in
a K3. I am only interested in general coverage reception of SWBC
stations, plus operating CW. I am a little unlclear about what filter
would be required for AM (reception only), with the KBPF3 option.
For CW I generally prefer
Does anyone know where I can get a 8-pin mic plug for the K2? Radio
Shack lists it but doesn't seem to have any. Can't find it at Mouser.
Thanks.

Ok, I've recorded several sets of filter settings for different
sidetone/offsets, so now I can change them in about a minute. Doing
this shouldn't be a problem for the rig, right?
If you wanted to you could put one set of filters in the CW Normal
slots and another set in the CW Rev slots. I
I'd like to know of a good procedure for the IF Alignment (L34). I
tried it with Spectrogram but I really don't see any definite best
alignment point; same for doing it by ear.
As for the AGC Threshold adjustment... I read somewhere (sorry, i
forget who) that you should adjust it just to the
I had been using 650 Hz for awhile but decided to go to 800 Hz for
some reason. It just sounds better to me now. Maybe becuase I got used
to it while using my code practice program; higher pitch seems to
sound better for QRQ.
I was thinking of doing a bunch of filter alignments at sidetone

Two signals 40 Hz apart are much easier seperated at a pitch of 400 Hz than

My headphone jack failed in short order. I am constantly jumping back

When I got a new jack from Elecraft I decided to add a

switch headphones speaker as needed.
Apart from the mini-plug being relatively fragile, it's also annoying
to plug unplug. It doesn't go very easily and I
I had been thinking about having a filter parameter memory card, where
you could store the bandwidth/bfo figures from a number of different
alignments and instantly recall and load them. Say you had five banks,
you could have four bandwidths at each of five different
sidetone/offsets. But I don't
I just installed one in my K2. I tested it by turning on a light
dimmer switch on the other side of the house which generates an S5
noise level on 80m. The K2NB totally eliminated it.
