Hello.
San Antonio has made the transition.
All of the new radios are this or this.

The old radios are being bundled up to be disposed of.
San Antonio has dozens of old motorcycle radios that are 2 radios in one box and an amplifier.

This was done to allow a transition from Smartnet to ProVoice.
If it is indeed a Specra, I have no interest, 800MHz trunking radios are super common.
But, if it is a unit that went from type I MotoTrunking to type II MotoTrunking, I have interest.
Motorola was not quite ready for full type II trunking motorcycle radios and so provided a fix, a MX300T talkie in a CVC unit that was later replaced with a STX unit and a 15 watt amplifier.
They also did this to pack sets.
Remember that San Antonio Texas was one of the first cities in the nation to go trunking.
My answer to all of this is simple, the radios are not worth fooling with, they are 800 MHz trunking and of no real value.
But the amplifier is set up to provide 15 watts of power, the legal limit.
This is an RF no tune module intended for operation in the given band.
That should be the only thing of interest as the radios themselves will not be made available to anyone, perhaps trade in?
So, what do Mexican get? a large box with a fused power block and an RF amplifier and siren unit.
I did not want the but did take the wiring and microphones as well as the siren speaker and antenna and all the extra switches and handlebar mount.
The amplifiers are rated to something like 40 watts at 800 MHz but are simply turned down.
There is NO filtering, put in a signal at 50MHz and a signal at 50MHz comes out, as well as anything else. :-D
30 MHz? no problemo.
I have some really old Motorola control heads from the UHF era that have controls on them.
I have ham talkies.
With narrow banding and rebanding and whatever else is planned this stuff is GOING to hit the market.
Some cities REQUIRE that the stuff be put up on public auction, and a lot of cities are going P-25 in one form or another.
But, I have another project to play with, and a use for the computer I got free a while back.
