That's a good idea. I'll see what happens!

Yes, I'm pretty sure it's a clone type. None of the CAT control
softwares support setting memories in the FT-817, if that means
anything. This is what the '817 manual has to say about cloning:

"You can transfer all data stored in one transceiver to another set by
utilizing the handy “Cloning” feature. This requires a
user-constructed cloning cable which connects the ACC jacks on the two
transceivers as shown below."

Sounds the same as the rest of the Yaesu cloning radios to me.

My Windows VM has been collecting dust for a while. I'll try this.

That would be helpful. I assume starting with the FT-2800 driver and
stripping out the guts would leave me with something similar?

Thanks for the ideas. Now I just need a weekend.
