Steve,
Per this link:
SDS100 I can pay for an upgrade DMR, EDACS and NXDN. So I am thinking that the SDS100 can receive NXDN. The cost of the upgrades are ok to me, if they actually track the systems. What is your opinion of this issue....I am leaning towards the SDS100 with the upgrades. I do travel around this area and having access to all radio traffic will be nice to have..... Once again, any and all comments, suggestions and recommendations will be greatly appreciated.
Ciao~

By the "EDACS" upgrade, I presume you are referring to ProVoice. The only EDACS system in Oklahoma was Oklahoma City, but those users are migrating to a P25 system, and from what I've read in the Oklahoma forum, the old system will be shut down once everyone has changed to the new system. You'd be wasting money to buy that upgrade, since EDACS/ProVoice is no longer supported by the manufacturer, and most every system has either moved on, or soon will be.
I have two NXDN Public Safety systems in my area:
Southwest Regional Communications Center Trunking System Profile
www.radioreference.com
That system covers three cities in Dallas County: Cedar Hill, Desoto, & Duncanville.
Lancaster Public Safety Trunking System Profile
www.radioreference.com
This one covers Lancaster, also in Dallas County.
I have no problem following either of these systems using the SDS100, or other Uniden scanners that also have the upgrade.
There is only one DMR public Safety system in Dallas County,
Highland Park. It's not a really active system, and they are moving to a different system here locally,
GMRS.
My TRX-1 can receive any of these three systems, but does not track them, and you cannot easily follow a specific talkgroup; you can do that with one of the upgraded Uniden scanners.
However, the SDS100 (and the other upgraded scanners) easily follow the
Megahertz DMR system, which has multiple sites here in North Central Texas. One major user is a local air medical provider, CareFlite, which has six copters based in this region. There are a number of other business users, not of interest to me, but the county hospitals in Dallas & Tarrant County (Parkland & John Peter Smith) also are on Megahertz.
The biggest advantage of the SDS100 (or SDS200) is the way it can deal with simulcast P25 systems. You do not have simulcast in your specific county, though that can be an issue in nearby Tulsa County, or if you went to OK City. If you travel to or through virtually any large metro area, you are just about guaranteed to run into simulcast either there or along the way.
The SDS series scanners, as well as the x36HP units (436HP & 536HP) are database scanners. So, if you plan to travel, you can use a GPS unit & let the scanner virtually program itself as you go. The 436HP is not as good on simulcast as the SDS100, but otherwise it is a good choice & is noticeably less expensive.
The 325P2, and it's base/mobile sibling the 996P2, can also be upgraded for DMR and/or NXDN, but their drawback is that they have problems with simulcast. That's not an issue for you in your home county, but could be if you traveled elsewhere. As these are not database scanners, you would need to program them for your specific area.
You do need DMR for your home county.

But there's very little NXDN in range of you, so you might pass on that upgrade for now. You can always add it later if more users near you change to that format. Don't purchase the upgrade if & when you purchase a scanner. You can do that yourself at MyUniden, for $25 or more less (per upgrade) than what a dealer would charge you. I would not pay for programming either, especially for an SDS or x36HP scanner. You can jump start your listening by updating the database & using your location. That can get you started while you get used to Sentinel & set up your own Favorites lists. Lots of YouTube videos on that, as well as a number of Wiki articles, can help you along the way.
