The 4th relay would NOT be switching any of the remote relays, believe it or not - it has ONE use - to light the LED on the front panel - Yes, I can use the NC side of the three in series to light it - I was thinking KISS for someone elses use "This is relay for antenna 1" etc, to keep it KISS - part count is up an extra relay, but makes explaining how to wire the board to someone super easy
