The Advanced Mobile Phone Service (AMPS) was an analog cellular mobile phone system developed by Bell Labs.
From 1968 to 1983 the Bell Labs worked out the system, while Motorola was developing the cellular phone.
Dr. Martin Cooper produced the first handheld phone "DynaTAC8000x", the famous Brick Phone.

I built several transmitters out of modified taxi radios.
It features a simple digital PLL (configurable by jumpers) and allows to directly connect the audio signal to the oscillator.
-This is highly recommended for the C-Netz, because signaling is done by sifting the carrier directly.
+This is highly recommended for the C-Netz, because signaling is done by modulating (shifting) the carrier directly.
One unit has a switch to change between A-Netz and B-Netz (2-meter version) and the other units to change between C-Netz and NMT (70-cm version).
I added an input to switch between two channels for the B-Netz.
(Whenever a B-Netz phone is paged, the channel must be temporarily switched to the paging channel.)
