Just purchased a BCD436. Made Favorites lists in Sentinel and downloaded with no issues. Can receive all as programed except for; Iredell Co. NC Fire, Police in the Towns of Davidson , Huntersville and Cornelius and Davidson College police. All in NC. I believe these are rebanded sites. Do I need to modify the Band Plans ? If so what are the base frequencies and the separation.

Welcome to RR.com!

I have moved your thread to the NC forum where it should get a better, more localized response.

What method did you use to import the systems?

Rebanding is only going to apply to a very limited type and number of systems.

Which systems are loaded?

Which systems are working?

Which are not?

Are you using any location controls (GPS, zip code, etc.)?

I used Sentinel.
Charlote USAI Region is the problem system.
NC Viper works great.
No location controls.

Keep in mind that Huntersville, Cornelius, Davidson are working off the Mecklenburg simulcast site (001), on North Meck Law talkgroup and CMPD North division (Huntersville). Meanwhile the Iredell talkgroups would be on the Mooresville site (009).

You may need to set up two systems, one for Iredell using the Mooresville site, and the other for Huntersville, Cornelius, Davidson using the Mecklenburg site.

I am using separate sites. Mooresville for Iredell and Charlote Simalcast for Dav,Cor and Huntersvile.

OK, that eliminates that issue then. Are you getting a "DAT" indicator on both systems, both sites? Have you tried putting the systems into i.d. search mode, to see if you are receiving any talkgroups?

Chances are that from Mooresville, the Charlotte site is going to be out of range.

I was wondering that too. Typically I can get decent coverage on the Mecklenburg site going up 77 but it falls off quickly once I hit Mooresville.

I am located very close to Davidson/I77.
Closer to Mecklenburg site than Barium Springs on Viper which I receive .
Not receiving Iredell County Fire on Mooresville site is a problem.
Sentinel loaded a band plan for the Mecklenburg Motorola site but nothing for the Mooresville P25 site.
Trying to rule out a rebanding problem.

There will not be any entries under "band plan" for the Mooresville site. Sentinel will load two entries for the Mecklenburg site - 0=851.00625/6.25 , 1=762.00625/6.25.

These are the default setting that should have been loaded when you imported the systems from Sentinel.

I'm trying to understand if you are receiving either or both, the Mooresville site and/or the Mecklenburg site. If you are receiving the control channel you will see a "DAT" indicator in the lower-right corner of your screen. It may be steady or flash depending on signal strength. Also, please let me know if you have these set up as two separate systems. Sentinel by default will load this as a single system with multiple sites, and you want to have them as separate systems.

Just curious - why?

Just my preference. You are right, you don't have to do that.

The talkgroups on the Mooresville site aren't carried on the Mecklenburg site, and vice versa. To me it just always made sense to keep them separated.

Ah, ok. In the end, even split and enabled, the scanner should be doing exactly the same things while scanning.

You can "logically" split them using site (department) quick keys without creating different systems.

I sometimes experience reception issues (radio doesn't stop on talkgroups that are definitely active) on the x36 radios when the radio jumps from site to site and system to system (of various types) but have never found exactly why. It is almost as if the radio doesn't take long enough to truly check each control channel properly. On the other hand, I've seen the radio stop on a talkgroup and never unmute. Seems if the decode quality isn't above a certain point, the radio either doesn't stop or doesn't unmute making it "seem" like it is working really well - unless you have another radio monitoring and picking up things the x36 is not.

As one might expect, monitoring a single control channel (one system, one site) tends to improve things (sometimes).

I'm always interested in tricks others find useful.

For some reason I've always struggled with the quick keys on the 436. On my old 396 the quick keys were second nature and I never had a problem with them. I think I just gave up on the 436. I keep everything separated by system and use the favorites numbering to toggle them off/on.

I agree with what you are saying with jumping control ch. I don't know why but it always seems to be better when the radio sits on one CC without having to jump to another site.

Off topic a bit - but I see you are using a G5. I just ordered one, and my code plug is all built and ready. I'm looking forward to trying it out. LSM distortion has been a pain for too long.

Yea, they take some getting used to.... When I first got the 536 and actually used it (for a time), I set up some quick keys and took a drive. I kept getting "nothing to scan" (or whatever the Uniden error is). Between that and the sun glare on the display, I was ready to toss the thing out the window at 70 MPH. But I don't let these things beat me - I kept at it and finally figured it out. I still apply them quite often in favorites lists - even when using GPS on the 436 (I never should have bought that 536).

Yup - with exception of simulcast - which when I lived in Maryland was a killer more than here in Brunswick County - I found the radio performed better on trunk systems if you hold on a single system/site control channel (as one might expect) and even better if you change the hold/dwell time to something alot higher than 0. If you're only monitoring that single CC and using the radio for nothing else (no priorities, no close call, etc.), I highly recommend setting the hold time to the max (255?).

Yes it has. A friend in Maryland bought several Unications due to the severe simulcast issues on systems up there. Once he got past some issues in programming, he couldn't say enough about them - so, I finally bought a G4. I wouldn't make that purchase prior to hearing such positive reports about simulcast reception due to the price coupled with warnings that there was a "no returns" policy.

I recently upgraded to a G5 (sold the G4 on eBay) because I got an offer I couldn't refuse.

For simulcast systems, the G4/G5 can't be beat. In Maryland, not only was I able to finally clearly receive all of the simulcast systems in the area, the Unication was also able to receive other P25 systems that were several counties away (usually using a RS 800 Mhz handheld antenna)!

However, here in southern Brunswick County, particularly when inside my house, the Unication struggles receiving county VIPER sites just as much as any other radio I have. Of course, VIPER isn't simulcast and wasn't designed/built (as far as I know) for in-building coverage. I don't know if this is a plug/thumbs up for simulcast systems, a plug for in-building coverage, or both.

We get to Myrtle Beach quite often. Sometimes I can listen to the new Horry County P25 system from home with the Gx and it definitely receives Horry on the drive long before any other radio I have.

EDIT: Forgot to mention - the Gx programming is a bit tedious. After creating dozens of systems and manually entering (cut and paste) well over a thousand talkgroups, I finally got tied of typing and wrote a proof-of-concept Python script to make programming a bit easier. I'm in the process of re-writing the script this week to make improvements.

I was in Davidson today, great reception on the Mecklenburg site all the way up to exit 30, in car with an 800mhz duck.
