If it's not on the repeaterbuilder site, then call the Harris TAC, if they'll even speak to you. They've become rather exclusive of late, generally talking only to those who have a contract with Harris.

The M7300 is one of those radios that will demand that the technician has excellent SMT rework skills
and a full SMT rework station for most repairs. If you have a Weller iron and hand tools, you probably
will not get far.

Not looking to repair the radio. Considering using the SOC board as part of software defined radio. Need the legends for the SOC to RF board interconnect

Thanks Steve C

What exactly are you calling the "SOC board"?

What frequency range is of interest to you?

Steve,
There are only two boards in the radio. (3 if you have the optional GPS receiver installed).

- Processing Kernel (PK)
- RF Processor Board


Here are the screen shots of what is on each of the boards:

Mostly the 2.4 ISM band. Also thanks for the info on the chips used on the boards. Could be helpful even without the schematic.

The M7300 does not cover 2.4 GHz.

I would not be using the RF board, Just the processing board, that is why I was hopeful to have the board interconnect pinout reference.

Thanks again, Steve

Have you considered cheaper, simpler alternatives?

Thanks, I have been looking around a bit, never seen that link. The only reason I have been contemplating the use of the M7300 board is no cost to me, has no value unless you are involved with first response system, very little resale value, and as soon as the unit is powered up, it will be "stunned".

I sent you a private message.
