For a demonstration, the easiest route would be to modify a 2-meter receiving downconverter from Down East Microwave or another supplier. Change the crystal oscillator frequency and retune the IF output to 10.7 MHz. If you have a choice of IF frequencies use 21.4 MHz as this would be closer to the usual 28 MHz output.

Hi,
I need help to find any good design for the 2m to 10.7MHz downconverter which I'll try to use for presentation linear transverter. Please if you have any or point me to any good books where to find?
Thanks for all answers,
