[TowerTalk] Old Top Ten Devices Relay Switch Box

[Ed Goss]

HI Les,
      
Yes sounds like the same box.  It appears it originally was meant to work with the TTD band decoder, and not an independent control head.  I like the idea of switching the diodes...then I can use one of the spare Ameritron control heads I have here.  Thanks to all who responded.

Ed,

If you are referring to the antenna relay box that is a diecast box with
six antenna ports and no markings except for a paper strip that labels
the ports I have the same one and had the same issue.

What I did was to reverse the diode for each relay on the PC board which
allowed me to apply +12V DC for the desired relay.

I have the original manual which I will be happy to copy you on if you
wish. I think I still have the modified relay box as well.
