There are a few of these available comercially.
A very inexpensive one is made by Jackson Harbor PressThe one by Jackson Harbor
uses 10 Mhz (http://wb9kzy.com/lfconv.htm)
I plan on building another that uses an external 10 Mhz freq sourceso I can use
the same DPS Disciplined Oscillator that I use for my K3.

Subject: [Elecraft] KX3 Non-ham band upconverter use
Good morning all,
I'm toying with the idea of building an oven-stabilized LF upconverter
for my KX3. Ideally, I'd want to move LF up to the 7 MHz band to keep
the math easy and to put signals into a ham band where the KX3 more than
likely performs its best.
However, not many 7 MHz ovenized oscillators out there. So, more than
likely, I'll have to move signals elsewhere.
With the KX3 designed as a ham transceiver, I'd assume performance
outside the ham bands isn't as good as in the ham bands.
1) Is this true?
2) Is there a preference for a non-ham band frequency range? IE: Is
there any advantage to 10 MHz versus 5 MHz versus some other range?
thanks much and 73,
ben, kd5byb
