Once I get to the Stage III alignment on my K2, I plan on using
Spectrogram to align the CW and SSB filters/BFOs. It seems that proper
filter alignment is a juggling act between the following:
1) Proper centering of the signal within the filter's passband: For the most
part, CW should be
Hi, Michael!
Criteria 1) is not possible at the wider filter bandwidths without losing
single-signal reception (hearing the signal on only one side of zero beat).
Consider this: you choose a sidetone of 600 Hz. If the filter bandwidth is
2000 Hz and you center the signal in the bandwidth, then
Hi
Actually this is fairly easy to do with spectrogram. First use the new method
listed on the Elecraft website to make sure C22 is set right. I use the 600 and
500 Hz tones on 10 Mhz WWV to get the tuning right on a 600 and 500 Hz marker
in spectrogram. Then go back and forth between TP2 and

Hallo,
just a quick note to the list that my new assembled KX1 serial number #585
with 30m module and atu also is alive. I made my first QSO`s two days ago on
40m and 30m. It works great - tnx to elecraft - perfect ! No proplems only the
selfmade
( first installed resistor was not the right
Michael,
Actually there is no real connection between hearing the same pitch when
switching between LSB and USB and proper filter alignment like there is with
CW and CWr.
The SSB passband will pass a wide range of tones even if the passband is
severely mis-aligned. The only observation one can
Looking for a K2 with most options, particularly the internal tuner and the
battery supply. Might consider a K2/100 for the right price. If you have a
K2 or K2/100 for sale please send complete details, such as condition,
options, serial number, mods and price shipped to zip 45324
Thanks

The biggest differences that I've seen between the expensive and cheap DMM's
are:
1 - Speed. Cheap DMM chips take a second or two to produce a reading.
Expensive ones are almost instantaneous. That's only a small nuisance unless
you are trying to find a 'peak' or 'null' in the reading while
Hi all:
I have spent the last 3 years building a K2 with all the add-ons. The
reason it took so long was that 95% of the work was being done by my 15
yr-old daughter, Zane, W2YL. She is a superb kit-builder, but she has a
multitude of interests -- especially athletics (swimming and
