Last night, I replaced a 2N3906 in the decoder/logic box that I apparently destroyed while testing the relays.  I’m pretty proud of my troubleshooting on that one…narrowed it down to the transistor in about two minutes.  Since W9RE had been driving the relays with another set of relays, he didn’t bother to put back-EMF diodes across the coils.  I think that should help protect my precious (by that I mean pain-in-the-butt-to-replace) transistors.  Both PIEXX boards are talking to the decoder correctly.  I just need to build some coax jumpers, install the diodes, and tidy-up the shack.
