I notice there is still talk about the 600M (472 to 479Khz) band and options
for the K3/KX3
Just a reminder that i have transverters available that work VERY well.
They have both RX and TX, RX features very tight filtering and high dynamic
range, TX output is typically over 10W
As standard they
I should have mentioned that the K3 transverter out (around 0dbm) will
typically drive the transverter to full output. (in some cases the IF drive
will need to be reduced by a few dbm's (easy on the K3)

Hi again,
A couple of people have commented that the price for the fully built is a
little high.
So
I have decided to lower the price to AUS$170
The kits are still a bit off, I suggest the fully built to those that are
impatient. (construction documentation is the main delay)
cheers, Graham
Thanks for the positive comments ED!
As you may have seen, previously I specialize in microwave transverters.
This was a Fun project to break it up a bit!
I have really enjoyed getting back to the basics and at the moment is my
favorite project :)
There is always improvements to be made and
Sorry, I forgot to mention that the mixer is an ADE-1

Gday all,
Ive designed and built a transverter board for the band, It is working very
well and is turning out to be popular.
The K3 is a superb radio for driving it and is what i'm using myself.
IF is typically 28Mhz but can easily be changed.
There has been some delays due to component
Seems there may be a problem for some with the first link.
try going straight to my website http://www.vk3xdk.net46.net/
or doing a google search on my call sign.

Prices are yet to be confirmed,
the kits should be around AUS$80 and
fully built boards AUS$200
It may seem a little expensive but I hand built them, tune and test which
takes a few hours.
(a limited number of fully built ones are available already at this price)

I would expect the relays to switch occasionally but they actually chatter!
(only when the rig is cold it seems)
Thanks for the replies.

Locking module installed, frequency stability much-much better!!! (2M
internal transverter)
Now very suitable for modes such as WJST Thanks ELECRAFT
Interestingly enough, the radio seems to have a frequency error over the
range of bands? (measured on GPS locked F-counter) Not enough to be of
Gday everyone,
Iv noticed over the last few days when the K3 is just turned on (from cold
for the first 30sec. or so) turning the tuning dial causes relay chatter
type noises in the transceiver!!
Has anyone had any experiences with this? The radio is only a couple of
months old.
Ive also seen
Thanks for the replies,
I would like to get the stability reasonable before a locking or similar
mod. (i think there's some basic oscillator compensation issues?)
A receiver in this class is greatly let down and WJST EME is out of the
question unfortunately!
Ill be trying some more mods soon,
Gday all,
Ive been playing with a elecraft k3 (with internal 2M).
Im finding the 2m stability awful! (audible drift on ssb!!!) I thinking of
putting a murata style crystal heater on the 116mhz? crystal to improve the
drift.
I wonder if anybody has tried this or has a better solution?
cheers,
