XTL2500 Acting odd.

[speaker-mic]

Heres the skinny. 1 XTL2500 Model:M21URM9PW1AN/Flash:500008-000484-6 is acting odd.

The system employs an old Quantar(working) and a couple of DVRS units.
All portables and other units work fine, this one only transmits in direct/talkaround.
No matter whats changed, it still does this.

Any ideas?

Unfortunately, a not so reputable shop tried to gaff the customer and the "DEAL" to assess/fix this didnt pass the smell test.
There were some other things that were going on but some infrastructure repairs took care of that.

When you say "this one only transmits in direct/talkaround" - what signs are displayed when the radio is in repeater mode and you try to transmit? Do you get a "bonk" tx denied sound, or does the tx light come on, just no repeater activation?

When is the last time this thing was on a service monitor for tuning?

Is the system/network you're trying to use a trunk or conventional 800 MHz system and do you have the system's licensee/administrators permission to use the system. If a trunk system, is the system designed for a Smart Net or Smart Zone architecture.

The radio is flashed for Smartzone, P25, and conventional operations.

I'm not well verse on the trunking subject, so I am not sure if the radio is flashed for Smartzone if the radio can operate on a Smartnet system. Also, I would need to bone-up on what happens when the DVRS feature is enabled/set in the CPS.

If conventional, the codeplug is probably not correct on that specific channel pair assignment.


Unless you are the system's administrator or licensee, I suspect that you do not have any legal station authorization to be transmitting on any 800 MHz system with a private owned 800 MHz radio.

I'm guessing the radio only transmits on talkaround and won't access the repeater/system? Being these are relics of the ancient past, when was the last time it was aligned?

In direct, it has the: |->| symbol.
In repeat its blank.

Tx is granted every time but it has the long 5 tone chirp and transmits and receives on the same frequency. All keyups are greanted, none denied. There is no repeater activation, ive seen the live monitor on the computer screen and panel lights in the shack. It was aligned within the last 2 years.

It only does this in the DVRS channel, the other P25 and analog are fine. It was setup as a cross compatable system. Not my design, only my inherited headache.

It is a conventional system, been pretty solid for a long time. This one in particular is the odd man out. I am sure you know what happens when everything is the same except a unit or 2, people notice. Thats why they all have the same configuration settings.

Odd part is, it will do trunk, it came from a trunking setup prior to being upgraded. Everything was cloned out from a blank plug and started fresh. Im sure it could be setup again for the type 2 and P25 systems again but the previous owners upgraded to the APX line to migrate to the TDMA trunk setup.

Hand me downs are great sometimes and sometimes not and with budget limitations, it can be a pain.

The pair is proper, same as all the others. It only does this on a DVRS channel. In regular analog and digital its fine. These are set up for cross compatibility [example a unit is in a valley and another is on a hilltop].

I did not set this up, only got the joy of sorting it out with an almost $0 budget...

If they can get a replacement, it may just become parts.

Aligned within the last 2 years. It accesses the repeater in analog and regular P25, just not DVRS.

Current firmware? (well last written over a decade ago, R20.50.10)

Old....
Heres the info:

8 MEG

Yeah that some old firmware.

Plus I would recommend a full PM on a service monitor. That way you rule out any physical issues with radio itself.
