Hi Guys,
Wondering if anyone has measured or experienced distortion on a KPA-1500 when
operated at low power, such as: 200, 400 or 800 watts? I ask because sometimes
I need more than 100 watts to make a Qso but sometimes it's fun to run the
minimum power required to complete the Qso. That
Does anyone know at what Serial Number Elecraft upgraded the KX3 RF board to one with
greater frequency stability? I am interested in finding one that is stable enough to
use on 6m EME with Q65-60A mode. Thanks for any information!

I have the Zoom Q2n video camera. I use it as a studio quality
microphone as well as a web cam and a stand alone video recording
device. I have only used a few of its capabilities too. If you need
stereo sound capability this tool works well.

Good Evening,
Weather has returned to normal: 40 degrees F, foggy with rain, and
humidity at or above 98%. Snow is in the forecast depending on
elevation and temperature. The forest has already been pruned, but I

The following 27 checkins were reported by Brian K1NW in Rhode Island who sat
in the Net Control Seat today with WB9JNZ Eric’s absence. Brian's cohost today
was Steve WM6P in GA. As always thanks to the relay stations John N6JW, NS7P

I think the fan speed setting is *minimum* speed, not fixed speed. The amp
will always speed up the fan from the minimum setting if necessary for
self-protection.

I expect that ALC is being used for two different parts of the transmission
chain.
Audio ALC would reduce the dynamic range of the audio. That automatically
reduces the microphone gain to maintain a consistent level of modulation. That
would be inside the audio part of transmitter, before the

Folks,
Using the KPA1500 remote program. There is a slider control for the fan
just below the temp bargraph. I can manually adjust the slider to give me
different fan speeds, so the control is communication with the KPA1500.

I have an HP-11 bought when they were new, which is an old and reliable
companion. I have “Retro 15C” on my iPhone which also works well. While I
generally don’t program them — I like the self-documentation of a real
programming language for anything complex enough to need a program — they work
I have a working HP25 out in the garage/workshop. The battery pack expired long
ago and I pried it apart and put some Ni Cad cells in it.
I have a 15C in the shack.
I had another one, HP41C I think, that failed. I can't find it so I think I
finally threw it away. Didn't like it anyway :-)
I still have an HP15C on my desk that I picked up when I was working
at the Ohio State University and taking EE/Computer Science from '79-
'84. It replaced an earlier model (probably an HP-25) in which both
the battery and LED module failed. The 15C is still ticking right
along with new
I agree with both Ted and George about building is half the fun, I built
several dozen K2s, K1s, and KX1s for myself and others. There is great
satisfaction in completing a build to have it powered up and receive those
