Subject: Re: [DRAKE-RADIO] TR7 Connectors

If anyone needs some of those tiny crimp-on RG-174 size connectors I have lots of them. Had to purchase 1000 of each for interfacing my 7-SP speech processor to the TR-7. (Product long out of production.) There is the chassis connector (called the lunar lander in some Drake documentation!), the coax tip female connector, and the coax crimp-on connector. I have the crimp-on tool, but I don't know how well a generic crimp tool would work.

I remember seeing them used on the clock boards for DECSystem 10 and 20. Million-dollar systems.

The reasoning behind choosing them are the very small space requirements and the fact that these connectors were not designed to be disconnected/connected multiple times.

BTW: Even the “great” Collins Radio Company used these junk connectors all over the very expensive KWM-380. All TenTec radios up through the Omni V, same deal.

Considering all of the innovations that went into the TR-series, I too have always wondered why they used those weird, probably failure-prone coax connectors... :)

Those connectors are REALLY chintzy. I think the center pin is just the center conductor of the coax itself. I wonder if one could upgrade them to SMA connectors?
