I have both the KAF2 and KDSP2. I prefer the DSP
because the filter skirts are steeper, and I can
get some Noise Reduction with it. Not available
with the analog KAF2.
Good luck and 73

Hi All,
The build of 5226 continues and I have a question best answered by the
serious cw dxers in the group. Which is the better audio filter for cw? AF
dsp on ssb has left me at best luke warm. And I don't do that much ssb dxing
if I can help it. So don't consider ssb in the answer.
Thanks to all who replied ... I didn't build my KPA100, I got it from
this reflector and (of course, I'm male) just installed it and didn't
look at directions. CAL CUR at 3.5 has solved the problem.

Glad you asked! It's left unpopulated on mine, and mine seems to work
to a T. I also seem to remember something in the manual about that one
being left unpopulated. You might try reading through your manual
again, since the control board is small and simple and it should be
easy to find C44 bei

fool out of myself in front on the home town boys, but then, to turn
around and do it worldwide is a completely different venue...

Wow. Perhaps we can get a bit more helpful. Pretty much every wire
going into or coming out of the K2 presents a very good possibility
for RFI intrusion. This is true for any rig. The low-level microphone
signals are a very good place for this to occur - for me it seems

I use a bug and an external keyer with the K2 in hand mode. The keyer
does two things: 1. When the keying speed control is set the same (or
nearly so) as the dit speed of the bug's, all dit "scratchyness" due to
point bounce and less than perfect keying is eliminated. 2. If I set

not a function of which antenna is selected, or any antenna connected. It is
steady in amplitude at 30 db over S9, and gradually rises in pi
Thank you, Alan, that is very helpful and will try that. I have had a
suggestion that the problem could be due to high harmonic content from
the 28MHz output from the K2, so I am continuing with various test to
establish the cause.

I doubt it's the cover holes. I've done some testing with the top and

amplifier without any problems. (QRP is fun, but sometimes...)
Is your problem band sensitive? Is your antenna resonant? I would

A good starting point would be to operate into a dummy load. If there's no
interference, then you're dealing with energy radiating from the antenna -
not a K2 problem. If there is interference, that narrows the possibilities
to the K2, the dummy load, the coax, and ... the power supply.

It is very highly unlikely that the holes are a problem. I think
you can discount that one. It would help to know what sort of RFI

I have never heard of a problem that required covering the holes, but then I
have not run any tests of RF leakage either. I would suggest that you first

I have a list of possibilities which don't need exposure here, but I do
want to know if the K2 with the rear cover it comes with with all of
the unfilled openings can allow rf into a place where it could be a
problem?

Thanks for the reply Wayne.
I'll check our mail server to make sure the blockage is not at my end. I'll
ping you later with a test message to confirm.

Hi David,
My suggestion is a coaxial trap or possibly a series LC to deck (use
a trimmer C). The insertion loss will be minimal. A single trap had
little effect on the feed Z as shown on my Tx but ideally a second
one about lambda/4 at 145MHz further down the feeder will offset the
effect at 145
Hm, I'm building along and it appears all my slug-tuned inductors um,
aren't there. Like, they weren't put into the kit. So, I have to wait a
few days I guess to get some. The toroids are easy though, they're
really not hard to wind. I'm left-handed but I wind 'em right-handed,
