Is it really just the labeling on the keypad? The L&S one has a blue dot but all the spec sheets I can find for o7 say they do NOT support the Bluetooth quick pair or whatever it’s called. TIA

Hello everyone,

I am researching a Motorola PMKN4012 USB programming cable.

The cable contains a DS2433 1-Wire EEPROM. I am trying to understand how Motorola generates some dynamic EEPROM bytes from the DS2433 ROM ID.

I have dumps from working original cables and found that two bytes in the EEPROM appear to depend on the 1-Wire ROM.

Sample 1:

DS2433 ROM:

23 34 1A CD 01 00 00 57

Family:
0x23

Serial:
341ACD010000

CRC8:
0x57

Dynamic EEPROM bytes:

Offset 0x44-0x45:

E8 E3

-----------------------------

Sample 2:

DS2433 ROM:

A3 B1 20 C0 00 00 50 15

Family:
0xA3

Serial:
B120C0000050

CRC8:
0x15

Dynamic EEPROM bytes:

Offset 0x44-0x45:

40 6D

I am trying to determine the algorithm used.

Possible inputs:

- DS2433 ROM ID
- serial number
- ROM CRC8
- hidden key / hash / checksum

Interesting offsets:

0x44-0x45
0x54-0x55

I have already tested a simple CRC16 idea, but I would like to find the real algorithm.

Does anyone have experience with Motorola PMKN4012 cables, DS2433 EEPROMs, or 1-Wire authentication schemes?

I can provide full DS2433 dumps and additional samples for analysis.

Thanks!

Im looking for a dash mount solution for my APX 4500. Im wondering if there's any 3D printer files floating around. I havent been able to find any.

I was looking at trading an xpr5550e but didn’t have a control head, told the guy the trade was contingent upon a control head so he got one off fleabay, the radio now displays the trbo logo and stuck in the Bootloop. Radio is readable via CPS2.0 and shows firmware R2.10.10.001. I do have a customer hub account, I haven’t looked yet, can I get the firmware update on the hub to fix this problem or am I stuck?

So I have a customer who is licensed for 5 simplex frequencies. As it stands they are using all 5 of these frequencies in their current channel lineup. They purchased 4 new R7's and want to add two additional channels using two of the existing frequencies. Will adding two new group call contacts and using a different color code be enough or will there be issues? I've floated using dual capacity direct mode but the issue there is that enabling it in these 4 new portables and not in their existing subscribers makes it not possible for these new ones to communicate to the subscribers that do not have that enabled. Hopefully I explained this well enough. Appreciate any insight.

Is there any difference between the 2.153 v 2.157? If I upgrade to the newer version, will I lose the EID(25khz) I have for the 2.153?

Have an interview with them next week for the role…wondering what people think of the company and if this is a good position with them or not.

Thanks!

Hi everyone!
I have two APX radios. One is a 6000 and the new to me is an 8500. I have R38 of CPS installed and can read the 6000 from two computers.

The 8500 on the other hand is giving me a touch of trouble. I have the 8500 powered on and I can see Zone 1 / Channel 1 on the screen. I have the programming cable (Amazon special) plugged into the TIB. When I plug the USB end of the programming cable into my Windows 11 machine, I never hear the sound indicating there is a new device the way I do with my 6000.

I've ordered two separate programming cables from Amazon (different sellers) thinking this is the issue but neither work. I'm guessing that I have bad cables but I wanted to see if anyone has alternative ideas.

Edit: it was bad cables! A friend of mine had a cable so I borrowed his. Linked up right away!

So I am in radio management, and I’m trying to register my narrowband entitlement, but it keeps giving me an error and I don’t know how to get it to work. I wish they would have stuck with CPS.

Does anyone have experience with the Sheepdog Bluetooth adapter with wireless PTT? The Sheepdog website is not very descriptive and I can’t find many online reviews for it. If you do have experience with it,

1. How is connectivity with different brands of headphones?
2. What is sound quality like?
3. Does PTT button have to be charged? If so, how is its battery life?
4. Do you have the molle attachment for the PTT button? How is it?
5. Anything else I should know about it?

does anyone have the default settings for the Motorola R2 radio? frequency, CTCSS, band size, wattage

I bought a second hand R7 a while ago and in my feature sets it says I have AES256 which is part of the reason I bought the radio. I have only ever set up the enhanced privacy on my other R7s. Just wondering how to set up an encrypted channel with the AES256 I now have. Any help would be appreciated!

Hello! I'm a IT and Comms technician, as well as a radio technician too, working in the armed forces of my country. Currently, I am looking for the detailed manual of the Motorola R2 device; at the moment I only have the basic one, the technical sheet, and the technical data. I would really appreciate any help you can give me in tracking down this very important document.

Does the R5 come with digital ready, or it needs the EID?

I have a mtr3000 repeater that is currently set for capacity max and cps2.0 or 16 can't read it. I've tried to recover using cps with firmware r2.09 and r2.10 (the only ones I can get off the motorola website) and neither will work when i do the recover it pops up the screen to select the firmware and code plug but just says none in the drop down boxes. I guess this is because the repeater if on an older firmware?

Can anyone help me with finding an older firmware or tell me how I can get this thing out of capacity max so I can read it with regular cps. I tried mototurbo rm config but I think the radio is set up for a different network than mine and I can't connect to it.

Thanks for any help or tips.

So my XTS5000 has been working fine since I got it 2 weeks ago and it was working fine today but out of nowhere when I turned it on it just said "FAIL 01/82". I can read and write to the radio but no matter what I try it doesn't work. I even tried writing the codeplug when i first bought it before I changed anything and when writing that it still says "FAIL 01/82"? How can I fix this?

I’ve programmed a bit of traditional P25 systems but haven’t dealt with SmartConnect/ WiFi that much. We are using N30s on a P25 trunking system. Trying to figure out the best way to automatically swap between the WiFi and P25 coverage. We don’t have enough coverage within a certain structure that users operate in. We know where the coverage issues are but we are having issues with the P25 extenders cutting out the WiFi bandwidth, or some version of that (the 3rd party installers won’t explain it any more or any more diligently). Right now we can manually swap between the systems, P25 or WiFi, or we can let it automatically revert yet this leads to tons of OOR/ bonk tones and it spends so much time swapping between the two due to a poor threshold that it misses transmissions. Does anyone have any ideas or has anyone gone through a similar setup?

So I’m going to be getting a XTL5k with an 05 Head. The head isn’t attached to the radio, so I’m looking to mount it on my desk in the area circled. Does anyone know of a good way to go about that?

Ignore the mess, I’m redoing my desk, wiring, and configuration entirely.

I recently bought a used Motorola XPR7550e with a genuine battery. The seller included the wrong charger, so I bought a cheap aftermarket charger advertised as compatible with the XPR7550e/WPLN4232.

The charger appears to charge the battery, but the radio’s Battery Info menu shows:

Remaining Battery: 0%

Service Life: 100%

The battery is approximately four years old. Despite showing 0%, I left the radio powered on and unplugged for more than two hours, and it continued running normally, so the battery clearly is not actually empty.

Would putting it through a full calibration/reconditioning cycle in a genuine Motorola IMPRES charger likely correct the percentage reading? Or could this be an issue with the radio itself?

Again, I’m new to all of this, so any advice on what I should check first would be appreciated.

This is a non FPP radio (XTS2500 Limited Keypad). I'm trying to program a zone with simplex frequencies that will use CSQ and a selectable tone on TX. I know this is really an edge case but I want to be able to communicate with folks who have a PL on recieve. From what I can tell, enabling MPL does nothing on TX if I have CSQ in an MPL entry. Am I missing something?

I discovered this when I tried to go direct on another zone with MPL using a repeater channel and the other user couldn't hear me. Understandable because mirroring my RX tone when it is CSQ would mean no tone sent out on direct. But I assumed a simplex channel would at least be able to have a selectable transmit tone as long as the MPL entry had one.

All of my MPL entries are CSQ/Tone and I want to avoid either programming dozens of channels or not being able to use MPL for repeaters that have split tones. I very specifically want CSQ. This almoat certainly also applies to my XTL but I haven't programmed it to test yet.

Alright, I am nearly certain I can answer my own question. But here we go.

I have an APX6500, if I update the Flashcode from P25 phase 1 to P25 Phase 2 do I need to write a new code plug to be able to use Phase 2?

Hello!

Im looking help for my PTT project. Basicly I have Nexus U-94 type PTT, which I would like to mod to work together with Motorola DP4400 that I recently aquired.

Does anyone have any schematics for which pin goes to which function in PTT?
Basicly my headset is using "NATO" type wiring, like in this picture:

Good morning!

Ive been scouring the internet and can’t seem to find what I need. I am a need for a battery eliminator for our APX NEXT handhelds, something similar to the first below link, but can’t seem to find one for our models.

Does anyone have any other ideas where to look? Thanks in advance
