I was working at Collins Radio in Cedar Rapids when that happened. Art
kept dumping money into the computer business, but was always behind the
curve technically. He might even have been able to sell some smaller

The KWM-380 may have been a "hot radio" in some people's minds, but I can
personally attest to the opposite. I have one, along with a number of KWM-2As
and S-Lines. The 380 is a horrible performer. The receiver is incredibly
noisy, obstructing reception of all but the loudest signals. The

It sounds like that signal was a harmonic of your primary signal. If it was
1KHz off, it might have been the second harmonic of a 1KHz audio tone.
These harmonics are almost certain if you are overdriving the audio chain, so
checking the drive is the first thing. Your drive to the radio at 4

Back in the late 70s or early 80's, when I was a teenager and a "lowly"

to win the radio, but barring that, seeing the reaction of those old

Dear Folks:
I'm not really a big FT8 operator, but if you want to work 6 meters,
that's where the action is. Recently, a local ham sent me an email

signal, a secondary wider bandwidth signal about 1 khz above my primary

Didn't he sell to Rockwell? Then I think some of Rockwell went to Boeing, but
I'm not sure which part was the radio part.
Can't say I've ever seen a Boeing Collins radio though :^)

I think that was it, the KWM-380, and I remember people describing it as

Always good to have your input, Jim ... but I think a case can be made
that when the K3 says its setting for this is"NOR", that should mean
power per band. After all, when you QSY band to band, don't you often
wind up adjusting the power?

That was the problem. Somehow, I had accidentally bumped the variable

Hi Pete,
Did you confirm that the drive power from the K3 was changing on 15M when you
adjusted it on 80M and vice versa? I’ve never had this problem 160M through 6M.
Sounds like something may be set wrong in the menu or a failure of some sort.
