[Elecraft] Trying to gauge interest

[Ken Arck]

If you look at the schematics of the KATU, you'll see the chain of 
shift registers on the KATU actually sends a signal back to the RF 
board. So the CPU sends the command to the KATU and if the ATU 
doesn't respond (via the MISO3 line), the CPU interprets that to mean 
the KATU isn't present

As for handling 100 watts, I don't see a problem as I use the exact 
same OMRON relay the KATU does and I considered inductance in the pc layout
