I too have an old Ham-M that I will be working on over the winter. This is
a project I could get behind!
Someone provided a link to manuals, but the links dont work :(
If I can get a schematic for it, I can throw together a PC interface for
this thing using a PIC or similar microcontroller. I already grabbed the
protocol for the EA4TX interface and can already see some room for
improvements (presets anyone?).
So... if someone can point to a valid link, or scan-n-mail a manual to me,
I can get started :)
Anyone else up for a development project? (I develop, you try to break it!).
