The KX2 will automatically fold back its power (responding to temperature) to
prevent thermal runaway or damage to its finals
That being said, it is routinely recommended that when running any 100% duty
cycle mode (e.g. typical digital text modes or FM Phone) one reduces RF output
to 50% of
Thanks Dave. I resisted using the ptt port setup because I thought vox would
behave just like it does with my wsjt and fldigi setups. Is selecting K3
instead of a com port just forcing winmor to send audio?
Thanks again,

Hello again
I finally sorted out the problem with my brother , K0ZK's Elecraft K3.
It was an oldie with a serial number in the 300s and it died on him in
the middle of a QSO. It has been dead for about six months and he is not
in the best of health, so I figured I would try to fix it for him.
Thank you for the feedback. I have never seen the radio get that warm
during my operating. Someone did point out about the third party heatsinks
available so I may eventually purchase one. I primarily am doing very high
duty cycle modes such as RTTY and the JT modes with my KX2 so I want to
I’m told Maxwell is still on the list for delivery of his Elecraft K4, and
patiently awaiting delivery after compulsory social isolation.

I believe the radio might shut down somewhere above 80 C.

I do not have KX2 but KX3.
KX3 internally set a PA temperature limit at which KX3 automatically reduces
power output.
Assuming that KX2 and KX3 are very similar, unless your KX2 automatically
reduces power output, the PA temperature is within the safe range.
I think running FT8 with 5W output is
This question was posed last October by another on the reflector in regards
to the KX3 but does not look like there was a response. I had posed the
question once to Elecraft support and believe my email got lost in the
fray. When I posted the question to Elecraft support it was a month after

Lee,
I’m having the same trouble. Can you forward the screen shot, or maybe post it?
Thanks.

XG3 obviously.

Well, the utility and firmware file.
Hello,
Does your K2 need repair? Tuneup?
Want to sell it, but it needs some attention before offering it for sale?
In addition to tuning your rig, I can also rescue a building project you might
have started some time ago.

Another very good book about Oliver Heavyside is
Paul Nahin's Oliver Heaviside: Sage in Solitude: The Life, Work,
and Times of an Electrical Genius in the Victorian Age:

Yes. However, Oliver Heaviside had the advantage of both vector
calculus and operational mathematics which he sort of invented. Maxwell
did it "old school." Regardless of who you favor, the theory took on new
meaning for me when a professor pointed out ...

I've built a couple of the small Elecraft kits in the past. Basically,
just stick the components on the PCB and solder.
The KRC-2 is a bit more more complex, some mechanical pieces need to be
assembled in the correct order or you get to remove them to solder in
some components. I was alerted
I have often recommended Daniel Fleisch’s book, A Student’s Guide to Maxwell’s
Equations, to my students. In it he credits G. F. FitzGerald, Oliver
Heaviside, Oliver Lodge, and Heinrich Hertz for simplifying Maxwell’s equations
to the few that we often see today.

I heartily recommend this book, the best I have seen on Heaviside

He had a tough childhood and became a telegrapher and virtually self-taught
physicist who laid the foundations for modern electrical engineering.
