PSR-800 No Audio on Trunking Systems

[teknishun]

I have a PSR-800 that was working perfectly until a couple of days ago.
I have not made any changes to it or updates, etc.

I have been using it only to do Unitrunker testing.
It has been plugged and unplugged from the pc USB port many times.
I have been powering it only from the USB port. The batteries were removed.

The problem that developed is there is no audio on any of the scan lists
that are in P25 trunked systems. The scanner scans and has the cc and a
good signal strength. The display shows exactly what it should.
But there is no audio on trunked systems.

I built a conventional scan list for HAM radio 2-meter repeaters and that
works great. It scans OK and there is audio on the conventional frequencies.
Also the Skywarn button plays the NOAA NWS channel info with good audio.

I re-formatted the SD card and did a complete download from pc to scanner
using the EZ-Scan software.

SO...I have audio on conventional systems and no audio on trunked systems.

What am I doing wrong?

Is it possible your local P25 system just rebanded? When that happens you frequently keep the control channel but the map for the audio channels changes and the audio stops working. I suggest re-downloading the system from RR DB.

It could just be that the control channel for the tower near you has changed. You can check the database link at the top of the page and then find your system and the tower you are picking up the system from and check the frequency to see if it's changed and update it in your programming or you can just use the update option in the software and update your scanner with the latest information from RR. The tower near me will work great for a year or two and all of a sudden they change the control channel and the scanner goes quiet and I have to update the frequency in the programming software and then update the scanner with the new frequency then it's fine again. I have some friends that I help with programming too and whenever this happens I know my phone going to ring with hey my scanner went quiet do you know what's up? I tell them what the new frequency is and they enter it in the software and update the scanner.

It's not always going to be that easy because someone has to find the new frequency and send in and update to RR so it will show in the database. At times I have to use the search function on the scanner to find the new control channel and send in the update to RR so it will so the change and then you can use the update option in the scanner programming software. It's also possible that your area was just re-banded but I was thinking that all of the re-banding was finished. The re-banding was when they went from 868.xxx to 853.xxx for example. In the area that I live in the towers use main and alternate frequency's and if the tower changes to one of the alternate frequency's and you only have the main frequency's programmed in you won't hear anything. Make sure you have both in your programming, they will be listed in the database as blue and read.

No audio

It is also possible they are now encrypted. Depending on your settings, you may hear a sound like a phone busy signal, digital noise, or nothing at all. Check the setting in your advanced feature of EZScan. You might also try using the search feature to see if that makes a difference.

Thanks ALL.
I got it to work. I took my working PSR-800 and copied it into the pc using the EZ-Scan
software. Then I copied the pc back out to the other PSR-800 that was having trouble.
I gave up trying to find the problem -- but all is working great now with both scanners.
It could have been corrupted data on the pc. Anyhoo - it works now and life is good!

I'm having issues trying to change control channels on the local site (Kellyville/OKWIN)on the OKWIN network. I've no idea how to change the control channel either through the scanner or the software.

I assume you are using a PSR-800? If so, you can only change the Control/Alt channels through the use of EZScan. You cannot change them with the radio keypad except if you were setting the system up as new.

If you already have Kellyville programmed you can update the Contol/Alt channels by downloading the latest RR database into EZScan. Once d/l'd the software will ask you if you want to update your programmed data. Say yes, BUT, be sure to uncheck box that says change Alpha Tags, AND check box that says only use control/alt freqencies.

A second way to change Contol/Alt freq is to Open EZScan, click on Trunked Radio System Tab on bottom, highlight OKWIN system in top box, click on Site Details in bottom box, highlight Kellyville tower line, manually change frequencies on right hand side.

 

[BenBrewing]

Yes, it is a PSR-800 and I'm doing a fresh install of frequencies as I just got the radio back from repair. Is the top frequency in EZScan on Trunked Radio System tab on OKWIN Kellyville site the control frequency?

 

[Swipesy]

I just got my PSR-800 back a month ago from G&G also.

No. The top Box sets up the OKWIN System.

The bottom Box sets up the Towers Sites and the Tower frequencies. Upon import tell the software to only import Control and Alternate Frequencies if that is what you want. If you want all tower frequencies for a particular site then leave the box unchecked on import.

 

[teknishun]

A faster way to do this might be to go to Radio Reference and look up the OKWIN system and the Kellyville site. The control channel is listed in red. Now go to the EZ-Scan software and hit tab Trunked Radio Systems. Then click on the system name under What Is Trunking. Highlight the site called Kellyville. That will bring up a list of freqs for that site. The only freq you really NEED there is the red control channel. Just update it in the list on EZ-Scan and then re-download to the radio.

 

[Swipesy]

The only freq you really NEED there is the red control channel. io.

This is bad advice. You should always put in the control AND the alternative frequency. Sometimes for maintenance and other reasons a site administrator will switch to an alternative frequency from a control frequency. If you only have the control programmed you will be SOL.
