I think I was lied to ??

We have a ASTRO T99DX+131W D04UJF9PW5AN, which was working fine in
a county trunking system, (just) listening to about 15 TG's.
The county 'switch" to "MARCS_IP". which is "Multi-Agency Radio Communications (P25) "
and the radio shop said the radio was "in-capable" of being used on this system.
can anyone shed some light on this ?

Thanks

Don

MARCS is a P25 trunking system. What's the flashcode of the radio? You're probably getting the straight story.

MARCS is still a SmartZone OmniLink system using P25 voice. You would need the SmartZone Omnilink and ASTRO voice option in the flashcode for it to work properly. At some point they are looking at swtiching over to a Phase 1 or 2 system IIRC, but it hasn't happened yet due to the sheer volume of orginal astro radios on the system.

You need at the least these in the flashcode:
G806 ASTRO IMBE Digital Operation
G173 SmartZone Omnilink MultiZone Operation

Just got through a presentation from the head guy of MARCS a few weeks ago. They are currently in the process of switching to a phase 2 system. Cuyahoga County has X2 towers online, but I am not sure of their switch yet. If they have gone online with it for day to day ops in the OP's county, them I doubt you're going to listen to it with an astro spectra.

is the new MARCS overlay a true P25 phase 2 or Ma M's proprietary X2 TDMA? Just curious.

Depending on his area, they will be moving to 700Mhz freq's, astro spectra will not support 700Mhz.

I stand corrected once I went back over the handouts. As far as I know for now they are going true phase 1, rather than Smartzone Omnilink, with the ability to switch to phase 2 at a later date.

In either case, it's still in a distant future considering the size if the system and subscriber base.

MARCS-IP is being used for day-to-day operations in many counties even though the system has not been built statewide. They are not planning an all-at-once migration.

OP, you are probably being told correctly.
