Steve,
Nice article on how you modified the K2 to be a 144-MHz IF for use
with mw transverters. The venerable IC290R was used by many for a
long time. I hear of some using the FT-817 which is selectable on
144-MHz output for 0.5/1.0/2.5/5.0w. I had one that I used to drive
a DEMI 10-GHz tr
My new, unbuilt XV-144 kit with optional crystal oven is still for sale. I
have dropped the price to U.S. $405.00, which includes shipping to Canada or
CONUS.

Steve,
Re: Low Power takeoff point in the K2.
A low power output from the K2 is available if you simply remove jumper
W6, BUT (and a BIG BUT) is that the power takeoff will be uncontrolled.
You have to drive the VRFDET line to send the power level back to the
MCU to control the power - the K60
There's been several good points made about my K2 internal 2m transverter
project...here's a bit of my thinking about why I went the way I did:
(1) Using an alternate transverter (VE3SYB) - I did consider the Transverters
Unlimited board from the Ukraine to potentially give me more output, but i
Looks good, Steve,
I did something similar a number of years ago. I put a low power DEMI
xverter in a pair of K2s but ended up with a birdie that was pretty
loud near 145.1 MHz where we had our microwave calling frequencies. I
ended up removing the xverter and put it in a different enclosure
Steve,
You might want to try building up part of the K60XV as part of your
project. Download the K60XV manual and its errata and look at the parts
list - you would need to add the K60XV firmware (and use MCU firmware
version 2.04 if you do not already have it). You would not need the
change
Great job! In the pdf you "hope it will help anyone thinking about microwave IF
rig alternatives." If you can go up, you can go down. I've been researching
630m solutions to help a friend get on that band. Unfortunately, I think I
caught the bug. Your solution to microwaves, looks like a way to

Interesting project. One thing seems a little odd. You use an attenu
For a while now I've been working on a project to install a low power 2 metre
transverter inside an Elecraft K2, in order to use it as an IF transceiver with
transverters for the microwave bands. I got it done this summer and used it on
10 GHz during the ARRL 10 GHz and Up Contest, as a "plug-a
It is cheap and accurate after OLS calibration with good loads. Attached 50
Ohm load was so so. I am using it when accurate impedance measurements are a
plus, including for LC. For instance with 160m antenna, measure, prepare
appropriate coil or capacitor, and the match is perfect.
