In one of your other posts you mentioned a Y connector. That's
exactly how I accomplished it. To the best of my knowledge, there is
no such animal available commercially. So, I made my own.
What I did was buy a few RS232 A/B boxes. IIRC, I bought them from
cyberguys.com for about $5 each (this was several years ago). I
removed the A/B switch, and rewired the connectors in a Y
configuration. Besides being relatively neat wiring, in a nice
enclosure, it was significantly cheaper buying the box complete, than
buying individual RS232 connectors!
Each radio's band data goes to a TTD Band Decoder. Output from each
decoder goes to a serial port on the computer and a Six Way antenna
switching box via the modified A/B box. In my case, the Six Way
control lines are again split with another A/B box to control the
Bandpass filters and stub switching (yup, stubs here, too).
If I had the forethought and motivation to draw coherent wiring
diagrams of what I did (as I think back to seeing the volumes of
documention of W2PV's station in the 70s), I'd send you a copy. But,
