Does anyone have a link to Astro Saber circuit / block diagram (handset)?

Particularly: basic difference to a "standard analogue" GP300. I assume TDMA but does Astro Saber go so far as a real basband to IF to RF? Is it handled by the DSP or an ASIC etc.

Any help greatly appreciated.

The AstroSaber block diagram is in the service manual (basic and detailed manuals).

I'm not a lawyer (but I did sleep at a Holiday Inn Express recently)
Because of copyright issues, it would be illegal to copy the block diagram and post it on the net.

Ebay has these service manuals for around $20. If your going to be playing with these radios, the service manuals can be a valuable source of information and would contain the information your looking for.

Enjoy your ASI - wonderfull radio!

Hi

thanks!

I already had bought the service manual for GP300 series from Motorola and it had very little in the way of circuit diagrams so before doing the same for Astro - I wanted to find out if it was elsewhere.

understood and all the best

Well I bought the basic and detailed service manual.....and neither seem to have a block diagram or circuit diagram of the astro saber digital mode of operation.

All I would like to know is how the digital radio basically works compared to a normal analogue radio.

I'd appreciate it if someone could just write even a few sentences like "audio comes in, goes though a codec first (?) gets converted to digital (bit rate/kHz?) then it digitally modulates a carrier (? in what way) etc.

best
