APX APX900 NAS issues

[swfluncensored]

Hi all,

I use an APX900 for NAS and need urgent assistance. I currently reside and actively listen to my local county systems with no issues at all. The one problem is that I am currently having issues with a neighboring county of mine, which up until this evening, I could not even hear from my house.

I am currently hearing snippets of sometimes clear, sometimes simulcast-distorted radio traffic from a neighboring county's sheriff's office. My radio, without red-lighting, is silently attempting to affiliate to the TRS. I know this because every time I receive traffic, I'm getting the "SYS-REG: xxxx" over the RID. This is not my only suspicion.

If I am listening to my county, no matter what channel I'm parked on (conventional channels w/ scan lists linked to the TGs), the traffic from the sheriff TGs always seems to supercede. No matter what scan list I am monitoring, the sheriff TGs will override the current channel/scan list and will begin "going off" so to speak, even if the sheriff talkgroups are NOT in the scan list I am monitoring.

The trunking system/personality settings are the exact same (vs the normal county), with the exception of the band plan/channel IDs (in trunking system). The zone channel assignment has been configured correctly as well. When I am NASing my home-county, I never experience this issue and my radio does not affiliate.

I don't know what to do.. or how to proceed. My radio is sitting on the desk, turned off, with the battery and antenna removed. Please help.

I am using CPS R30.

You posted this in the Facebook APX group as well. Your radio sounds like it’s affiliating with whatever system you’re trying to illegally monitor. It’s people like you who give this radio hobby a bad name.

Sell the radio and buy a damn scanner.

So is Brianna your dad, sister, cousin, uncle or ??? These types of posts won't help Brianna's quest to get a "media" radio.

My guess is something isn’t quite right in your programming. If you’ve programmed it correctly, you shouldn’t be having these issues from either system. But, without seeing how you’ve set your codeplug up, no one can give you the answer you’re looking for. It’s a needle in a haystack.

That's a weird one and I'm going to tell you I've experienced something similar myself, well, kind of. And on a Harris radio, no less. Set up strictly to scan, "never affiliate" check boxes checked, etc...it still had problems with one system that was at the extreme fringe of range.

That right there seems to be a common factor. That the problematic system is in fringe coverage. It's like the radio doesn't quite obey its own programming rules when it's in a fringe reception scenario.

Let me make a suggestion or two. Not sure if this will help...but try. Configure the radio as if it was encrypted and strap it to secure only operation.

I don't have an APX900 file on hand to read and play with in the APX software, but if you send me yours, I'll take a look at it and see if there's anything else I can suggest.

I'd also see what can be adjusted in the APX tuner software, which I also can't do because I currently lack an APX to read out, and thus don't know what's adjustable but I'd definitely adjust TX output all the way down and drop the TX deviation all the way down if possible.

Funny how JonathanRamos and Michael Levers have the same issue here and facebook....

Is the "Full Spectrum Control Channel Scan" checked off or on?

I have to say it is a little concerning how "Brianna" appears laser focused/obsessed with this system. Knowing she/he/insert pronoun has an actual subscriber that may be affiliating should set off someone's GenWatch triggers and hopefully result in an RCM job to inhibit.
Reading stuff like this reminds me of why I have job security and why I never get lazy when looking at ZW/GW affiliation viewer.

That’s their cousin.

would you happen to have that talkgroup in the announcement group box in the trunking personality?
That was my trick back in the XTS days when the scan list was limited to 15, I could squeeze in another talkgroup but it as it functions it would unmute while showing another talkgroup

If you insist on having NAS pay one of the guys to do it that actually know they’re doing before you pay them to unbrick your radio on top of paying to get programed right.

Put the TX Inhibit option on the menu and enable it, then put the antenna back on, What does it do then? Is it set to smartzone/inter/intra wacn? Are the only control channels for that particular system in that specific trunking system? As asked above, is full spectrum scan enabled?

Experts: What does SYS-REG on each unmute transmission mean again? I've seen it mentioned before but don't recall. Some kind of roaming thing or maybe not. OP said couldn't receive that county until now. Or maybe it thinks it something to do with on the fringe, I dunno, if its suddenly being heard when it wasn't before, but op says sometimes clear sometimes not, I dunno, I spit ballin here, not a big expert.

Sounds like he should use Txin and there wouldn’t be any problems

If only it were that simple.

 

[ElroyJetson]

Use a Harris radio and then it IS that simple, with a few stipulations.
Gotta be honest about it. Much as I love Motorola's products, when it comes to using a radio as a public safety grade scanner, Harris is the way, the truth, and the light. Far easier to use one as a "safe" scanner than any Motorola.

It is trust me.

Just stick to a scanner and you wont have these issues..

Except tagless APX8000’s are all over E-Bay, CPS is easy to get from a friend, or buy on E-Bay, and everyone has a friend who can use Depot to make any APX do anything. I don’t think Harris radios are that “user friendly”.

 

[ElroyJetson]

Except that CPS doesn't provide a true "receive only" option for any Motorola radios while RX only is a native function in Programmer, RPM, and RPM2. With Harris radios you don't have to mess around with system keys and weird NAS programming techniques, you just program straight and set every talkgroup to TX disable and auto login set to never. And it's not like "opened up" versions of RPM/RPM2 are hard to get. Heck, you can get a dealer to actually sell you the unrestricted programming dongle for several hundred dollars. Something you can't get from Motorola, no way.
I find that Harris radios are as easy to program as Motorola, maybe even easier given that Harris gives you less configurable options.

Setting up a trunked system on a Harris radio is easy. Create the trunked frequency set. Create the trunked talkgroup set. Create a system that ties them together. Make sure your site IDs are right and it'll likely work on the first try. That's most of it.
