Batboard

I recently obtained a VHF maratrac (T73XTA7TA7BK) A9 and it has a switch on the control head that says: clear/coded. I fired it up and it sounds like voice inversion. It has a small board with the numbers: 45807-L9059 on the chip. It also has many wires attached from the chip throughout the logic board. I am just trying to identify this board and what type of scrambling it is. Just prior to the voice inversion starting, I also hear what sounds like MDC on the audio. Any help appreciated.

When I said A9 head, I meant A7 advanced head. I had spectra on the brain... Just clarifying...

Sounds like a Transcrypt board. They use GE STAR (I think) for signalling the code to be used at the start of each transmission. Does it produce a periodic clicking sound as well?

I found a picture of what it is:

ANI-F
Multi-Format ANI Encoder

The ANI-F encodes ANI and Emergency ANI in Motorola's MDC-1200® & MDC-600®, DTMF, five-tone, two-tone, burst tone, or M/A-COM's GE-Star™.

Any threads on this or info.....
