Hi guys, question I have this control module/head for the spectra. I see it has two pin looking connectors. I was wondering does anyone know how this connects into the main unit? Like which part do I need to complete this.
Thanks
Thanks
Okay thanks hmm seems like a lot of work. You said you are sending some of these to the scrapper. Do you have any of these radios complete that you are willing to sell that work?
Our agency doesn't sell any communications equipment, don't know why. We destroyed about 110 Master 3 VHF 110 watt base stations and several hundred radios including Aerotron CC as well as Harmon Trainmaster CC Syntor RR coach (like the Spectra coach) a few years ago. We also drilled holes in about 3-400 GE MPA and MRK portables. I was able to get about 50 MRK's for a PS agency in Putnam, but otherwise the powers to be don't want any responsibility of radios leaving the RR.
OP here is the correct radio deck you need to go with your head: Motorola Spectra MBR43KME1170AD VHF Railroad Clean Cab Radio Unit Module 3 | eBay
The 19-pin cable mates the head to the radio deck. You can use either connector on the radio deck, or run two heads off the same radio. The 6-pin connector goes to the telephone-style handset, which you can also connect to one or both heads, or the head and the radio deck at the same time. The big 4-pin connector is for power, 12 or 72V.
Railroad Spectra has pinouts for every connector EXCEPT the 19-pin control head connector, but it should be a straight-through 1-1, 2-2, etc. cable. They are Amphenol mil-spec connectors and IDK where to tell you to look for them, aside from hamfests.
