I would look into some small vfo kit.
Either a DDS or something based on Si570.
I use this one:
The Si570 Controller and Frequency Generator Kit #2
http://www.qsl.net/k5bcq/Kits/Kits.htmlYou can set the frequency to any multiple of what the display reads.
( for Steves convertor board set to X2 )
The only thing I don't like about this one is the pushing in on the vfo knob and turning for different menu functions.
But once it's set up, that's a non issue
