Hello,

I've got one Stephens Engineering Associates SEA 112 HF marine
transceiver..

Yes, it's a crusty old radio, but I'd like to fix it up. I do repair
radios from time to time, but I'm not familiar with this design at all.

1. How are the frequencies programmed in? I see no crystals or diode
matrix for programming the channels as I would expect in an older set. I
have not taken the sandwich of boards in the center of the radio apart..
the bandswitch seems to go through there and I'm not going to mess with
it just yet. So, is this an EPROM-programmed set?

2. Has anyone managed to convert this model for ham radio use or is it
best left as is? (I've read at least one case of a mariner throwing one
away, so they must not be too valuable..) I've got no antenna tuner,
just the set with microphone.

If anyone has the manual including schematic/service data, I might have
an interest in it.

Thank you,
Patrick
