Great reference page about SABER radios

[speedbird727]

I came across this Motorola SABER page and was really impressed. Thought it would be nice to share:

It is a complation of most of the information that is out there already. Too bad the sabers are now pretty much only good for 2M 70cm and T-band..

I wonder what the mystery module actually is?

 

[CQDX]

Government mode FPP I think. Looks a lot like a module I saw in an A9 Spectra.

The tilt switch does sound plausible, I could see that being a feature PS would want.

 

[Astro Spectra]

It is not FPP.

Its a Bovine burglar detection tool

I spent hours this evening looking at this website. Thanks for sharing it.

The "chip" on the mystery module is an interesting package. In 1989 this might mean it is a mixed-signal hybrid module.

He seems to think that it came from the Dutch PTT, which was the telco and post office before privatisation. What special applications might they need?

I have head of a custom SP they did for Spectras that involved a Real-Time clock of some sort that was implemented in place of the STATUS/MESSAGE and DEK features. The called it their ComEd mod, I believe. Somehow the STATUS or MESSAGE function would send a time-stamp or something like that, I never got a complete description of how it worked.

This does seem like it has an RTC in it, there is what looks like a cheap clock crystal and another precision crystal, or maybe that's a custom IC in the can of some sort - hard to tell from just one angle. Either way it has a very prototype-ish look to it, like there were not many made, perhaps.

Something else interesting is the long number on the bottom, that could be a unique ID or something like a silicon serial number, and that can may be an early Dallas 1-wire device or something similar.

Motivating.. I need to get some time to work on my Systems Saber.

Baker to Vegas is what is taking up a lot of time here. Getting radios, antennas, ect ready to go.

If that custom module was Tx'ing that 5 tone on a schedule, and it came from a telco operator it would seem like that it was used as a radiophone in lieu of deploying a more sensitive AMPS or DAMPS Motorola Microtac cellular system next to the Iron Curtain. Uncle Sam was messing with Ivan right up until the KGB left Eastern Germany and East Berlin. That 5 tone could have been a primitive affiliation signal to the nearby towers, "similar" to how some of the old radios got handed off between towers.

Man I remember my first cell phone was a Motorola MicroTAC Elite that my father handed down to me. It was a beast and you could hear other people on the line if the adjoining channels were being used.... Motorola California back in the day....
