Iain,
It may be worth going back to basics and reading up on doublet antennas
as well as open wire feeders. The critical length is half of the top
plus the feeder length and this should be adjusted so that it isn't
resonant on any band you wish to use. This because it is easier to
match a

I run Winmor on my K3 KX3 and find it very frustrating that Winmor resets the
mode back to SSB with each automatic frequency change. I need the mode to be
set to DATA A so that the compression Equalizers are disabled, ALC is
optimized, and for the K3 the rear panel connectors are enabled. Are
Hi all,
I have just purchased a set of those all metal knobs for my K3... I did
not really realize just how heavy they were...
The thought then occurred to me that the encoder shafts for both the
main and the sub tuning may not be able to take the additional weight...
Is this a valid worry?
I think you’ll find that Elecraft uses a premium ball bearing in their encoder
and it is up to the task.

I know that it's best practice to use DATA A mode for digital, but I use
Winmor all the time in SSB mode and don't run into any problems. I don't
even bother turning off the compression and EQ, either. Have you tried it
this way, and if so what has your experience been?

It is the total KX3 current drain.
Just set a band other than 2 meters, and the 2 meter module will power down.
Manuals etc will be on the website in due time.
Thanks for the quick and clear responses. This looks like a must-have

If you're using Winmor through RMS Express, go into Rig Configuration in a
Winmor session. Make sure you have selected Elecraft
I've found a solution with python... The problem was getting it to not
interpret '\xB2' as an escape sequence, so I just re-encode it with string
escapes, then do a string replacement:
source = 'DS@1\xB200\xB325\x80\x90'
source2 = source.encode('string-escape').replace(r'\xb', '.')

Hi all,
Are any interested in a pdf of
Construction of a Rhombic Receiving Antenna, US Army Signal Corps,
March 20, 1943
It's 37 pages
The last year of my enlistment was spent as one of three operators
selected to reopen K2USA in 1964. General Duffy Brown, a ham, was
embarrassed to discover that the station was boarded up and couldn't
participate in traffic concerning the AK earthquake. I left my slot as a
crypto instructor
I'll also throw in a bit. Department of the Army, Tech Manual, TM 11-666,
also has a lot of information on the rhombic designs and implementation, as
well as a lot more. Mine is well worn and dated February 1953.

Hmm... I don't seem to have this issue with my K3. I use RMSExpress and

Make sure you're running the latest version of RMSExpress and WINMOR.
There was an issue with a version released since the beginning of the
year where the radio would go

Yes, I have also had similar problems with the KXPA100 (SN#0876)and have
already composed and sent a letter to support. The letter is much too detailed
to reproduce here but I also suspected a firmware glitch. My unit was working
flawlessly until the upgrade. I'm sure the problem will soon
Elecraft is right on top of it; I'm also confident we'll have a solution fairly
