Yes and when running PSK-31 if you don't get IMD reports of between -21dB
and/or more like -29dB then most likely something at your station needs
improvement. Usually overdrive either in the audio system or RF path is a
contributing factor. ALC action is often one culprit. Some radios leave
Specifically about PSK31, that encoding needs a very linear transmit system.
The 25 W recommendation keeps the signal and the peaks in the linear region of
most 100 W amps. Modes that do not use phase shift keying on a single carrier
might not have the same linearity requirements.

Hey,
I seem to recall something you said a few years ago about accidentally hitting
one of your T1 QRP autotuners with 100 watts for a short period and it
survived. That being said, not sure I'd want to be in the same county with an
AX1 connected to a KPA1500 putting out full power, LOL! The

Just joking. Emphasizing the very broad nature of our product line. Frightening

Yup. I mostly use FT8, JT65, and MSK144 on 6M and 160M. I generally run
as much power as I can on 6M, and on 160M to work EU or AF. OTOH, I'm

Hi Rich,
The AXT1 tripod adapter has a threaded, stainless steel 1/4-20 PEM nut. So you
can attach it directly to a standard tripod.

It can be made to work if you build an adapter. The microphone jack
pinout is shown in the KX3 manual.
If you don't have the skill to read the mic jack pinout and relate it to
a plug, then you likely should develop that skill before you attempt to
build an adapter. Some basic wiring knowledge

Haven’t seen a response from him yet, but he may be taking about 160 meters.
From what I have read, that may be an acceptable thing on that band, given QSB,
band conditions, and antenna limitations.

A question about your statement that you run 400w in digital modes

I pretty much ignore HF usage as I am not on HF very much (primarily

What is the fixed delay between KEY OUT going low and RF coming out of a
KX3? The K3 has a CONFIG:TX DLY setting, but I find no equivalent in the
KX3 manuals. The concern would be RF hot switching if the external
amplifier relay is too slow.

Jim, my antenna is somewhat unusual. It is a Sommer XP-708, where the

Hmmm. 40M is not very wide (only 4.2%, as compared to 80M which is
