Aki,
At D2, the AC voltage could be power supply ripple, but the regulators
should smooth that out.
Because you show about the same AC voltage at all these points, the most
likely problem is your DMM. You might confirm that by turning the power
switch to OFF and checking the AC voltage at D2.

I appreciate your comment.
I decided to continue building.
My DMM may be too old. His age is over 20 years or so, Hi

I have a K2 which has a strange quirk, it has developed a thump

can't tell what the DX op is sending.

The Acom 1000 uses a vacuum relay for switching. I found that using the
standard T/R delay of 5ms led to some complaints of key clicks. So I use
a longer setting for semi break in (25-40ms) and that works well and

I'm not sure there is a problem. I've always found W1AW at 7047.5, 250 less

I don't have an Acom amplifier, but a friend with one sent the following:

With the FT1000MP + ACOM, if you want to use fast changeover / QSK, it
is recommended that you use the returned ACOM 'ready' output to
'release' the MPs RF.
ie, the MP has a
I have never had a hot switching issue with the K2, the timing is more
than adequate even with TR set to 0
I have even tweaked my K2 for faster QSK
Perhaps Wayne could comment on the timings but I have never seen an
issue here nor have I a problem with Keyclicks with either radio in QSK

How about a filter that corrects bad CW spacing?

Pass.

Pass? Oh, but it would be great! I could finally work those guys who
use bugs! :-)
I could also see a filter that would change the speed of the CW. It

I have been given the opportunity to purchase a 2nd hand Howes swb30 VSWR

Having just completed my K2 and only recently been following the
Reflector for K2 topics, I wondered if there was a popular list of user
modifications which can be added to a K2 apart from Elecraft's standard

Any advice is

My next project is to try /PM with the KX1.

G'day,
Many thanks gents for all the responses on and off the list. Much good
info, much appreciated. It leads to the conclusion that if the opposition
is the chosen route the 1000 wins over the 1010, quieter and 6M which by
current prediction could be humming big time in a few years. Will
Thanks for the interest (and couple of scammers...), but both units have
been sold and are on their way to a happy home in Illinois.

I must disagree - when the SSB filter widths and corresponding BFOs are
correctly set, the variable XTAL filters can be quite usable for SSB

First of all, the lower -3dB frequency corner of the passband must be near

I cannot provide a demo at this distance, but I can assure you that a
properly aligned K2 with an optimized AGC threshold will certainly be able
to 'pull signals out of the mud'.
For field ops, the K2 has the following strengths:

Very good receive sensitivity
