Found a reportedly working condition one of these radios at a local secondhand marine supply store today.  Followed me home for very little money.  Does anyone have any experience using this set on amateur frequencies?  Channelized set, capable of SSB and AM, I’m guessing it’s capable of about 100 watts output.  Have not found much information on it online so far.  Someone else posted a thread on a marine electronics forum on how to use them on amateur frequencies but very little
Info there.  Someone mentioned that the operating frequencies were set using programmed settings on an EPROM….

Here’s a stock image of one of them.

Thinking perhaps a DDS might be used to develop the required excitation to the mixing scheme instead of an internal PLL synthesizer?
