The nice thing about this radio is, all oscillators are derived from a 30 MHz master oscillator, which can easily be synchronized to the 10 MHz OCXO. In my tranverter, this OCXO drives the transverter (10.136 MHz <-> 0.136 MHz), so everything is driven from the same reference. I didn't check if the IC706 can be modified to generate a signal at 10.503 MHz (+/-). If so, it could be used as a duoband transverter for MF+LF, using the same mixers, only different bandpass filters in the frontend. Cheers, Wolf DL4YHF .
