If so, have you tried telling chirp you have a 2800 and seeing if it 
will accept the 1802 clone? Or the 7800 for that matter. It won't decode 
the memory correctly, but that's the easy part.

The 817 is a clone-type? I figured it'd be a CAT type, although maybe it 
will do both.

For the Yaesu radios, you just have to initiate a clone from the radio 
side and do something on the PC to look at what is being sent and send 
what the radio expects in return. I often run pre-existing software in a 
Windows VM using portmon to capture the traffic and then 
reverse-engineer from there. Most yaesus are expecting to send a block 
of data and get back a single ACK (0x06), so it's not too tough to fake 
out the radio until you figure out what needs to be done.

I think I owe Eric an empty shell stub driver for the FT-270 so maybe 
that would help you for yours as well.
