NX5200 DMR question

[jcefd10]

Copied this from my post on the NX5XX FB group, figured I'd ask here too.




I have a DMR question. I'm loading 2 channels in a pair of NX5200's for a neighboring FD. THey are DMR channels that are encrypted, and I have loaded the enhanced encryption key in both radios, and have the key entered into the list, etc. I've had success doing this before, but this time the DMR agency claims they can hear the traffic coming from the NX radio, but the NX cannot hear the traffic from the Moto's. Is there something specific I have to look for? I have the Talkgroups correct, have double checked the Slot, CC, and both RX an TX freq to make sure I have everything correct. What am I missing?
Thanks in advance

Does the Key ID match the other radios as well?

 

[jcefd10]

Yes, as far as I know. I programmed them exactly what Moto printed out. They’ve given me 2 sheets with the channel data and mine matches to the T.

Now, speaking of ID, these 2 radios wouldn’t need a specific Unit ID for some reason would they?

Each subscriber needs a unique radio ID.

Can the MSI radios hear each other?

ETA…I’m guessing the MSI radios can hear each other. Should have asked if the Kenwoods hear each other.

Ive turned them back over to the owner. I live
Too far away from the repeaters to be able to do any testing. I only was able to hit it once.
He should be able to tell me tomorrow if it worked or not.

So he says they still dont work.
Each KW radio had a unique id, I have the key loaded properly, the TG right, and even de-selected the dual slot direct mode. The Motos can still hear the KWs but KW cannot hear Moto.

DMR Encryption Type set to 1 or 2? Groups ID Scan checked? OVCM?
Is OTA Alias used?

Those are the things that have tripped me up before. I have no issues between Moto and Kenwood DMR, simplex.

 

[jcefd10]

I have no OTA Alias,
Encryption is set as DMR, the Enc Key, Key ID of 1 (this may be wrong)

I do not have Group ID Scan checked.
I have the Encryption type set as Type 1 currently. Which upon reading, it says the radio runs in Type 1 even if Type 2 is selected when using Enhanced Encryption.

OVCM, I'm not sure. I'm still hunting that setting.

The bandwidth and timing is very tight and unforgiving in KW. With mmdvm based repeaters I’ve had the exact same experience with DMR & P25 (not set up right) but not with a Moto repeater. The Moto subscriber units have much more tolerance on pulse width in particular. I don’t know what repeater if any that you are using. I would want to know if repeater is properly aligned. If direct, msdm is touchy—I never use it because of reliability issues.
Main takeaway is that Motorola radios will tolerate out of spec signals much better than Kenwood. My opinion is KW is too tight for the real world.
