NX-1300 K2 and NX-3300 NXDN compatibility?

[oniell121]

Hi!
I recently found myself managing an NXDN conventional system at my day job with nx-1300's using NXDN. In a previous life/job I did this with a MotoTrbo DMR system but have never used kenwood radios and used NXDN until my current position.

I am wanting to use an NX-3300 that I have for my personal use at work (I manage the license, my name is on it, and I give myself permission ). I purchased the CPS for the NX-3300 (nice little radio) and I sucked the brains of one of the 1300's out and duplicated the system and codeplug as completely as I could into the 3300. However, I'm not able to access our repeater or break squelch on the simplex channels. The NX-1300's and repeater are heard just fine by my 3300. Any ideas? I have codeplugs for both of these if it's any easier.

Things I have tried:
NXDN conventional with NO RAN - Still does not open the radio.
Analog - Works fine between radios.
Analyzing the signal using DSD+ - Both radios decode fine and even show the same RID and Group VCall.

Is there some incompatibility in NXDN protocols between the 3300 and the 1300's? Seems odd. I feel like I have to be missing something simple here.

If I remember correctly, the unit IDs need to be different, you cannot hear "yourself" through NXDN. Also, the repeater may be set to RAS based on unit ID, ESN or both.

 

[oniell121]

ESN might be part of the culprit for the repeater I suppose. I'll pull the programming for it and poke around. That shouldn't explain the simplex channels, but man I'm gonna feel stupid if it's just the fact they both have the same unit ID's. Haha

 

[oniell121]

No such luck. Different RID's still not opening the RX on the 1300.

 

[tweiss3]

narrow vs very narrow?

 

[oniell121]

Good thought, but all radios are on 12.5khz.

 

[oniell121]

Is there any chance of a protocol variant mismatch (KWD-3500CV on the 3300 vs. KWD-1200CA/KWD-1201CD on the 1300)? I thought that it would be backwards compatible, but I have two feature settings for the NX-3300. Only one is authenticated so I can't test the other one.

No, shouldn't matter. NXDN conventional is NXDN conventional. I run a lot of different NX series radios on NXDN trunked and conventional without issue. If the NX-1300's are the NU model, then they have NXDN from the factory. The NX-3300 will do NXDN out of the box, no license required.

Is the Green RX light coming on when you are transmitting through the repeater or simplex?

Remember that the NX-3000 line will only do one digital mode at a time. If you currently have DMR channels, it's not going to do NXDN.

That's what I thought. The 1300's are all NX-1300NU K2 variants and showing NXDN from the factory. DSD+ hears them both just fine and decodes no problem, so I'm fairly confident in saying it's sending the frames it should be. The 3300 is set for NXDN not DMR right now. I did discover that the hard way after I bought it that it wouldn't do both. Meh, oh well. But no, no DMR channels programmed.



Yes, the green LED lights and blinks when the 3300 transmits and the 1300's show the little signal icon. It's hearing it, it just doesn't seem to care. The repeater does not open, though since the exact problem occurs on both simplex and repeated channels, I'm suspicious that it's something else generic. Both radios are set for RAN as the audio control with both Decode and Encode RAN's matching.

OK, that's useful.

I'd get another set of eyes on the programming file. Often it's something that you've stared at for so long you may have gone blind to it.

If you are running in Narrow NXDN (12.5KHz), this part doesn't apply so much, but on the 6.25KHz/very narrow systems, it's critical that the radio be right on frequency. Too much off and it'll choke on the decode. I've got somewhere close to 500 radios on my NXDN system and I almost 14 years, I think I've only had one wander off frequency enough to cause issues.

Radio works fine on analog, I take it?

Yes, radios work fine on analog. It's just NXDN operation. And I could totally see how 6.25 operation would necessitate a very aligned transmitter. These are all 12.5 "normal" narrow.

I'm perfectly fine paying someone to take a look at the code plugs, though I will be paying for it personally since the radio the company owns work with each other just fine. Either of you take on any "consulting" work for a one-off codeplug?

We'd do it for free if you want to load it up in DropBox or something. I wouldn't be able to look at it until Monday, though.

That's extremely kind of you. Can I PM you a link?

I'm in no hurry. Not operations critical at all, haha.

 

[mmckenna]

Sure. I'm about to head out of the office, so first chance I'll get to open the file would be mid-day Monday.

Im a paramedic that works bankers hours these days, so no problem.
