Possible Alignment issue?

[natedawg1604]

So I just received a used XG-25M that I recently ordered, and it seems to have a major problem. I've been programming it with RPM14, it writes and reads just fine with no errors whatsoever. However, the radio doesn't appear to decode P25 audio at all, either in trunking or conventional mode. In conventional mode it TRANSMITS P-25 audio just fine, and it will receive Analog audio fine as well.

However when I key-up from another radio on a P-25 conventional channel, the XG-25M will show an incoming signal (very strong dBm shown in FEC mode), but the audio basically sounds like what you'd hear listening to P-25 on a analog scanner. And, when I scan individual voice channels of a trunked radio site in P-25 conventional mode the same thing happens. Project 25 (P25) - Signal Identification Wiki. Also when monitoring a local trunked system it constantly displays "CC SCAN". Does this sounds like an alignment issue? I'm thinking I could have an encryption setting messed up somewhere, but I disabled all the ENC settings I could find. And, the radio TX's just fine in the clear on a P-25 conventional channel.

Also I would note the individual I bought this radio from states he tested it very recently and it received P-25 audio just fine. Does this sound like an alignment issue? Or what else could I be missing here?

Update: So after taking a break from this project I changed some minor setting in RPM and now it works great in Trunking mode. I think I had a channel or zone assignment reference messed up in RPM. Anyways this is an awesome radio, the audio is very crisp and clear, it should work great in my vehicle.

For some reason I still can't get it to decode a P25 simplex channel from my XTS 5K, perhaps there is a setting in Astro25 CPS I need to mess with.

Upload your codeplug so I can take a look. It's possible you have a setting wrong or you might even have a setting turned on that shouldn't be.

I sent you a PM with the codeplug, thanks!

Alright going to take a look now at it now. I'll let you know if I find anything

Are you using enhanced CC by chance?

I HOPE NOT... that will cause the radio to affiliate

No not currently, as my second post on this thread indicated I got trunking to work. So far I'm only using fixed ProScan. However now that you mention it, I do have a question about Enhanced CC.

A post in here from last year stated as follows:

I have also had success getting the radio to ignore other systems in Enhanced CC mode by entering in the System ID for the site NAC prior to clicking Enhanced CC (at which point the site NAC box is grayed out).

Can anyone confirm if this tricks Enhanced CC to automatically ignore other systems (wide area networks) but still specify site preferences for the system you want to monitor?

I've not yet tried dynamic ProScan, but from what I've read it doesn't let you specify site preferences, it just roams to adjacent sites. I'd really like to specify preferred, least preferred and "never" preferences.

be very careful... it may work but your radio will ID will show up in the system history log

Does it show up as a registration request? Also how would that work with "agency" radios affiliating to system A (let's say Mayberry University boiler room operations), that randomly attempt to roam onto other systems they aren't authorized to use when the boiler room crew go on road trips for training seminars?

Why aren't the Mayberry boiler room vehicle radios at risk of getting stunned ever time they go on a road trip?

Huh? No it won't. It'll just tell the radio to scan a set frequency range if it doesn't find a control channel it likes.

AFAIK; that is NOT how enhanced CC works (or even what it is for), unless Harris has changed it, Enhanced CC is just a method for the radio to perform band-scanning to find the system and control channels for that system.

It does not (and should not) impact unit registration or group affiliation. If you are setting up a Harris radio for NAS, and the radio affiliates then you have other settings that are incorrect in your mission plan.

That is exactly how it works and what it is for and you're completely correct.

exactly. Enhanced CC has nothing to do with registration.

 

[IFRIED91]

ok I’m trusting everyone… gonna see how it works when compared to ProScan

 

[gatekeep]

At least for the XG-100P, so long as you mark group set talkgroups correctly with just the "Receive" group option (all other group options, aside from perhaps Scan are unchecked), the trunked system Auto Registration is set to Never and in General Options "Allow P25T Unsolicited Affiliation" is unchecked, the radio should NEVER transmit to the system being monitored (i.e. ghost radio).

The more I think about it, it would have to work this way; otherwise subscriber radios would try to affiliate on all types of random systems they aren't allowed to be on, and would risk getting stunned etc.

If you're the library security guard or deputy assistant traffic meter repair person, I'm pretty sure you're gonna have very few radio channels on your own system, let alone other agencies systems.
