[Elecraft] Modifying the K2 for use as an IF radio for the microwave bands

[Don Wilhelm]

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 
changes under the RF Board to add 60 meters, nor would you need the 
relay and bandpass filter components in the upper left of the schematic.
You would need the components in the lower right of the schematic so you 
could control the low power output with the power knob.  All connections 
to the K2 are via RF Board J13.

That addition would allow you to remove the attenuator and automatically 
switch in the 1mW output whenever you select a transverter.

You may be able to obtain a bare K60XV board from Elecraft at a decent 
price.

73,
Don W3FPR

I got it done this summer and used it on 10 GHz during the ARRL 10 GHz and Up Contest, as a "plug-and-play" replacement for one of my aging FT-290Rs.  I have just finished writing this project up, as it may be of interest to other microwavers.  The description is at
