missing audio

[flyboy4545]

Used it today. Worked a little better but stop about an hour later. Turned it off and back on and it worked again. Did notice some traffic started a word or two in. I believe that the P25 signal.

Used it today and worked fine for about an hour. Turned it off and back on to get it to work again. Did notice sometimes that it will start a word or two late.

Is this set up as NAS? If so, how many talkgroups are you scanning at one time? I typically set up mine with one talkgroup per conventional channel, so I know that it is only listening to a the talkgroup that matches the conventional channels name. Some people put more than one or the max that they can have and that can cause the radio to unmute late and or miss parts of conversations. I also have one copnventional channel as my first channel that has the max talkgroups on the scanlist and I name it "SCAN." That way I can scan several talkgroups and if one of them gets my attention, I can then turn the radio to that channel, so it won't miss any traffic.

The Charlotte system is simulcasting . I live in Davidson so I have the north end in my scanner . There is 5 towers . If you program your scanner with all 5 towers it will jump to each tower . You only need one tower in your scanner . I own 8 scanner .The sds100 sds200 home patrol 1 bcd536hp bcd996xlt bc785d bc796d bc296d and I did have a bcd436hp. Where I live now thy all work great now because of the new tower up hear .

I have 6 talkgroups per one conventional channel.

 

[rescue161]

I would only have one per channel. You can have more, but you'll end up missing traffic, like you are experiencing now. What is happening is that a talkgroup will become active, but your radio may not be on that particular talkgroup at that instant and it won't get anything at the speaker until the radio stops scanning on that talkgroup. This is why the first part of their transmission is cut off. Then of course, later on if there is a delay between the parties conversation, your radio will start scanning the other 6 talkgroups and will miss other traffic. If you want to scan more than one talkgroup, just make the first channel will 10 talkgroups and name it SCAN. Then, on the other channels, just keep it to one. The radio will scan fine on the SCAN channel and will not miss anything when you turn to the dedicated channels.

Okay i will try that. Thanks

 

[Soundman]

Yes that could be your problem . Also if you have to much in your scanner it could run slow .

 

[flyboy4545]

The scanner is on hold all the time on one talkgroup. I just use the master file it came with. Still learning how to program.

 

[rescue161]

If you are still having trouble with the scanner after setting the correct Astro25 Band Table, then it is more than likely experiencing problems due to simulcast. The XTS5000 should work great once you get the scan lists changed to 1 single talkgroup per channel (except on the ones you label as scan), because it is not affected by simulcast problems.

Seems to be better but one of the xts radios is still stopping. I think its the rf board or tuning issue. Ill get it to the shop soon or if you know anyone else?

I'd like to comment on the NAS part of this thread on the XTS5000. I will be rambling

It could be an alignment issue. I will be rambling here. Is the Ultramediate filter setting Radio Wide set to 8.7 or 5.76? If not try 5.76khz. Is the trunking system set to SmartZone? I've experimented the settings on a system near to me where Disabled/Smartzone made a difference between clipping of words on scan. Smartzone eliminated the missed calls but

You say the radio works for some time and then stops working. To me it sounds like the radio may be switching to another site based on the adjacent site control channels, which may not have the traffic for the talkgroups you wish to hear. You may have to adjust the Trunking Personality, Preferred Sites to Always/Preferred for the sites you wish to hear and enter the Site ID/RFSS for those sites you wish to hear so it won't switch to the other site

 

[flyboy4545]

It is set to 5.76 and smartzone. But it doesn't have preferred sites listed because I only have one system programmed. Does it still need to be put in?

 

[rescue161]

If you were local, I could align it for you, but Chrismol1 is correct about your radio switching to another site that isn't carrying the talkgroup traffic that you are monitoring. This is the nature of the beast when using NAS. If your radio was a legit subscriber and affiliated, it would receive the traffic just fine no matter which site that it was registered to.

If you are using the long whip antenna, you can try switching to the stubby, so the radio won't roam that other other site. Hopefully you'll still be able to hear one site only with the stubby and hopefully that traffic that you wish to hear will be carried on that site. Remember, a legit radio has to be affiliated and actively on the talkroup for traffic to be brought to that site. If there isn't a demand by legit subscribers, then that traffic will not be routed.

 

[flyboy4545]

Okay, Ill try that. I do drive trucks and might be that way in the future. Thanks for the help.

Yes, if it set to smartzone it will see the adjacent site control channels in the data stream and roam to a better site based on signal strength. It seems as if the radio is locking onto the closer tower than the one which you wish to hear traffic from

Try this. Navigate to Trunking -> Trunking Personality -> Preferred Sites tab and enter the site ID you wish to hear in hex. Next to that is the drop down menu for Preferred Status select Always for that site you wish to hear and should stick to the site entered

 

[flyboy4545]

Okay. so for Charlotte mecklenburg it should be 1 for id, Always, and 1 again for RFSS?

Okay. so for Charlotte mecklenburg it should be 1 for id, Always, and 1 again for RFSS?

If you check off smartzone + check off the omnilink tab none of the site IDs or RFSS matter but if you have omnilink off and smartzone disabled you will need the correct Site ID and omnilink RFSS which for mecklenburg looks like 1 site id and 1 rfss. 853.8125 cc right?

Do the preferred sites thing and report back if it works or not, theres one other thing we can do if it doesn't work which is locking it to that specific site and RFSS which seems to be 1 but don't go out of area without tx inhibit on or it will transmit in my testing which is why I suggest Smartzone and Omnilink is both enabled and checked off which will not transmit to try to lock on to the other system site ID

 

[flyboy4545]

okay. so far seems to be better.
