I am the parts delivery guy :-) there's a great one transistor one resistor circuit for doing this that I have used in the past. I'll bring some relays and back emf diodes too Brian soon to be vp5/n9adg

Be sure to have your friend bring a relay robust enough to handle the load presented by the relay coil in the SB200. Don K7FJ Tnx for your comments, guys. I'm at VP5W, and no Radio Shack on the island :-( I did bring a little relay interface, but the reed relay has given up the ghost. Fortunately, we have one op coming from Seattle next week, and he can bring a replacement. It is a borrowed SB-200, otherwise I would have installed a soft-key mod. Oh well.... Elecraft had better hurry with their KPA800!
