For those interested in such things, I see an aftermarket 70MHz Internal K3
Transverter with 28MHz IF on ebayuk. It is made in EA9. Item # 121290408912
also shows on ebay.com

I had the same issue with my kx3. Investigation revealed that their was a
dry joint between the power socket and the PCB. Soldered it properly, not
had the problem since

I did for a while use that signal for my transverter interface, see
http://g4fre.com/k3vhf.pdf and http://g4fre.com/K3_PTT_sw.htm
IT got messy when I changed XVn settings, so I moved onto sniffing the
frequency in the rs232 stream and switching transverters based on that, see

Wayne has been promising writing that bit of the software since the KX3 was
launched!

There was talk by Wayne when the K144XV was introduced that the K144XV could
be wired for a separate 144rx ports, but I have seen nothing written up so
far.
I noticed that there was a 3 pin header (normally with jumper) near the
unused cable outlets marked "144IF" in the box cover. Investigation
I am still waiting for 10MHz to be available as an IF band on the K3 to
enable a 10MHz rubidium or GpS standard to be used as a local oscillator
While I wait, I use my anan-10 sdr which produces ~5W on the band and has
had qsos

Both my early edition K144XV were not unconditionally stable and were swr

I think you will find that the 3:1 swr is because it is oscillating "out of
band". Try listening on a scanner. I have experienced this on my two k144xv

Having tried the K3 with the high spec oscillator and with the external

It would make the maths even easier if one could set XVn IF to 10MHz (and
XVn RF to 0MHz), one could then use the K3 external 10MHz reference as the

As far as I knew the KX3 supports none of the menu settings that you mention
until Wayne writes the software. They only work in a K3.

Following the listed procedure made made my KX3's previously iffy
performance on 6m digimodes acceptable and even just about acceptable for HF
QRSS.
I used the 5th harmonic of my K3's 10MHz GPS locked reference as the

With the CQWWSSB coming up next weekend I decided to work on solving the
nagging issue of not having an HF band decoder for my KX3 to automatically
select antennas and switch the Low Pass filters. I am using the RS232 data
from the KX3. The writeup is at http://g4fre.com/KX3_RS232_hf.htm

I met the same problem with the K3 and devised a switching system based on
"sniffing" the rs232 data. See http://g4fre.com/K3_RS232_sw.htm It can
decode/drive 8 transverter bands. It gives a 1 of 8 band output and a 1 of 8

next tuesday"

The WE9XUP beacon on 70.005MHz sure makes a lot of appearances in Texas (17
times last year, twice this year already)even though its pointing away

I was also involved in the beta test. I was/am using the "K3 as supplied"
5ppm oscillator and a rubidium 10MHz source and I managed to maintain 2Hz
accuracy at 50.26MHz (40ppB)which is fine for the VHF/microwave weak signal
modes I needed it for.
