APX7000 Expansion Board & Encryption

[Fuel4300]

Where does the encryption algorithms physically reside in the APX7000? In the 'expansion board'?

The main speaker is connected through the expansion board so it does not operate without it. Also, curiously, the radio will power up but will not go into self test mode with the expansion board removed.

If the encryption does physically reside in the expansion board (MHLN6977A) then this is a departure from the Astro and Astro 25 lines where the encryption module is an add-on and not a integral part of the system.

I am guessing the answer is no but does Motorola make a jumper or blank board to replace the expansion board?

The encryption IC (MACE- Motorola Advanced Crypto Engine) is part of the main controller board. All APX are encryption capable, they just need to be flashed for the algo you want.

So this is a flash upgrade you have to order with a dongle if you want to add another form of encryption other then ADP?

Negative its done just like a xts algo upgrade with a KVL and a pcmcia flash card with your upgrade info on it. Also some of the gray market APX either have no MACE IC or its non functioning making software ADP the only choice.

Grey market junk.....that is why I only buy new from Moto! I learned the hard way with an XTS...

Eh, never said they were junk. I have seen some that look factory new inside and out, others not so much. I own one and it has no issues but I've seen others that look like they were trashed and re-cased. Funny thing was I actually had someone tell me most the APX on ebay and for sale used here are still under warranty; Obviously that's not true, most don't even have tags and 90% of those that do are homemade imitations.

Good luck with it. Ebay...I bought a "like new" XTS5000R with all tags and still had lens protector on it.....one year later the feds came and took their stolen radio back leaving me with nothing for my money. It was just not worth taking a chance, bought my APX from moto with the options I needed. With our GSA discount the cost was around the ebay specials anyway.
