My first PSK-31 contact seemed to go very well. I simply adjusted the MIC
level (Line) until there was 5-7 ALC bars. The adjustment was quite smooth.
Then I went off and did other things and I'm concerned I changed something.
Now I have to turn the level way way down on the USB Audio CODEC (-16.4

Good Evening,
Twenty meters was interesting today. Signals would appear for a few
seconds and then be gone. But normally they came back again and again.
Reports came in from Alaska to Connecticut, Iowa to California but the
closest was from about 16 miles away. Forest Grove, Oregon sits
That is way cool!

I noticed today that picture of the K4 in QST does not show that split
screen.
Is there a separate panadapter for each RX?

George,
Solid wire will eventually break if it is flexed - and it will break
right where the terminals are attached.
Stranded wire that is soldered will also break - right where the end of
the solder that wicked up the wire stops.
The best is stranded wire with crimped connections made

My novice call was WN7SUA living in Arizona but I never upgraded ( even
though I think I could just have taken the test for Tech Class). 10
years later I got back in ham radio as N4ZPT while in Virginia. When we
both retired and moved back to Arizona I requested and
I don't think any automatic noise reduction system is intended for use
on Morse code. The way to reduce noise on that is to use a narrow filter.
NR is really only intended for speech (or in the wider world, music).
The key characteristic is that only a small part of the spectrum is
important
Interesting data, Don. I wonder if there is any information about
resistance variations between soldered and crimped terminals. One might
think that, with stranded wire, even a good crimp connection might not
solidly involve all of the strands, and might additionally deteriorate

As I've written in the past, there are 3 places which affect the audio
levels. As a good rule, all three need to be adjusted and all about
the same value. Thus the computer SPKR level needs to be about 30% to
40%, the WSJT-X PWR slider about 30% to 40% and the radio line gain
about 30%
Bill & all those who replied,
Thanks. I had tried turning everything to
around 52 in the windows device but that
did not resolve the issue. I dropped it to
1/3 and indeed that resolved the issue.
I've no idea why things are so different
than they were but They are what they are.
Thank you!
That’s the one. The problem is the WECC map does not have many geographic
references. Just distribution stations and converter stations. The other line
you referenced is 345 KV according to the WECC map. It Sierra Pacific power.

I have found no substitute for DXBase either. I have tried them all but stick
with it. The problem with most software IMHO, of course, is that it's written
by software people rather than regular human beings.
I put myself on the list for a K4, but I'll be pushing 79 years of age before
When it comes to eliminating extraneous noise, I have always found the

Mostly, the results were about the same as any other rig out there. Kind

Running DXBase from within Win4K3Suite using windows 7 or 10 Pro has never
been a problem. It fires up just like any other logging problem I have.
Speaking of DXBase I have used it since 1988 or so and really can't find
anything better. Sorry to say it will never see any additional improvement

In a word “yes”. Given that in order to match the RX performance of my
existing K3/P3 (dual RX, K3S synths) it would require me to purchase the
most expensive K4 version, then to me the only possible advantages over my
K3 would be improved SSB TX IMD and improved RX DSP noise reduction.
