I've just recently bought a used K2 /100 for use at field days with my
local club ( to save my own K2 from getting hammered too much ! ) . I'd
like to use it with a remote ATU . The output of the K2/100 is reduced
to 20 W with an Elecraft ATU installed and the TUNE button pressed
is it po
As mentioned by Bill, condensation and corrosion are perhaps more of an
issue than cold storage. Be careful if bringing cold equipment into a warm
room, condensation can quickly form...
Most amateur equipment doesn't mention storage temperature, only operating
temp. By way of an example a Rohde an

There is no documented method to set a lower
TUNE power when a non-Elecraft external ATU
is used or when no external matching unit is
present. The TUNE button on the K2 keys

Steve,
I am not sure if this feature was always available on the KPA100 or when
it was included (Don, W3FPR may know) but when the power is set above
20W, pressing the TUNE button will reduce the power to 20W until the
operation is terminated. If you hold and press both the TUNE and DISPLAY

I'm looking for the KBPF3MDKT option that locked the K144XV to the master
oscillator. If anyone has one excess to their needs please contact me off

Thanks. Bob

The Cha250 b is NOT an antenna capable of greater than 100 watts for any
length of time. It is a 5:1 unun hooked to a 23 foot aluminum radiator. It
needs to be 30 feet in the air and if that happens it will function like a
vertical OCFD. Still it is only good for 100 watts. When running a tuner

Just to be clear, you do not need the KAT100 ATU for this feature to
work. The K2/100 will lower the power to 20W (if set above that) during
a TUNE cycle.

Fully agree. The specs for the CHA-250B say a maximum of 75 watts for
digital modes ... i.e., continuous duty modes. That pretty much says
what the actual heat dissipation capability is. If he was trying to put
500 watts into his antenna in almost any mode, it is probably toast ...

Actually, I was only putting around 200 into the antenna, and it's doing
fine. I've been continuing to make digital contacts without the amp and
tuner. The antenna works great for me. I reached 50 countries during
the past few weeks of testing. Fortunately, I fully understand what was

If you were putting 200 watts into it on FT8 that's almost three times
the manufacturers rating and you're lucky you didn't fry it.

Do you mean upload them to the radio once, or play them from the

I think if you want to record them to the PC then you would need to use
N1MM or similar logger to play them during the contest.
You can record them to the radio then play them back via a keyboard

My apologies to Steve and Dave W8FGU!
I re-read the KPA100 manual and learned
that the K2/100 DOES reduce TX power
to 20 watts when the TUNE button is pressed
and the POWER control setting is above
that level.
I have my KPA100 integrated with a KAT100

The receive part of the penalty, from a lossy antenna, only applies if
the dominant noise source is after the point of attenuation. That's not
generally true at HF.

circulators and isolators to put passive losses in on only the tra

The K3 very conveniently includes switch actions in its CAT vocabulary,

I've plugged my paddle (tip = dit, ring = dah) into the side jack of the tuner.
I can press the Dah (RING) contact and after 2 seconds while in sleep mode, it

One note I should add - after the "INFO" procedure (emits "L0" with yellow
LEDs, followed by string of individual flashes with Red LED), I noticed relays
clicked once at the end of the red LED sequence.

David,
True but IIRC I was replying to a message where he said the SWR was flat
through 6m. Usually, somewhere between 20m and 6m, receive losses do count.
