Can someone possibly help me out here? Why is it when I am listening to KPD the channel will go silent for hours and then start picking back up right in the middle of something? Then I can hear them again for a few hours and then it does the same thing. Been doing this for a couple months. It's not that they are quiet it's like my scanner just cuts them out for hours.

2398 is listed as a Kilgore PD patch on the Gregg County Longview site. I am wondering if there is a problem with the rebroadcast?? See if you can hear them on another Talk group?? I don't think they are using the old system anymore, listed on the screenshot below... Here is an article where they switched over TXWARN months ago. You may have to see if you can find the new Talkgroup.
Kilgore PD's new digital radio system goes online
The City of Kilgore has announced Kilgore Police Department has made the switch to a new digital radio system.
What site are you listening to? Generally, you will only hear the talkgroup on a particular site if there is a radio affiliated with that talkgroup on that site. Ensure your radio is on the Kilgore site and you should hear everything.
If you are only monitoring one site it's likely they are moving to a different site, sometimes this can happen every hour or so , you hear them , then you don't , the solution, if that's the case , is to program another site if there is indeed another in your receiving range ? If not there's nothing you can do.

I have their TG 2398 programmed in and that's where I listen to them. I have KFD and GCSO TG also. All these agencies use the same tower now. I listen to these for work as the company I work for is on the wrecker rotation for these agencies. GCSO and KFD I never have these issues with. Right now for an example. KPD has been fine all day. Right now there is an accident on I-20 in Kilgore. I heard KFD and KPD both get dispatched. KPD officer checked in route. After that transmission KFD TG continued to roll fine like always but I haven't heard KPD in over an hour. I know KPD was using their radios at this time because my company got called out for this accident and I never heard once the officer got on scene, or called for the wrecker. BTW I'm using a Whistler 1040.

I agree, listen to the Kilgore site. But do this. Set your scanner to search for all Talk Groups, not just ones stored. You will probably start hearing a bunch of traffic. But see if you hear the Kilgore traffic. Document and store the new Talk Groups to your scanner. Report them to the RadioReference for Database updates. You can then change your scanner to the stored ones if you want. I am thinking that the 2398 Talkgroup was a Kilgore VHF to Longview 800 crossover repeater they had setup so the 2 could communicate without 2 radios. Let us know what you find!! Good Luck!!
2398 was linked to Kilgore's VHF system but seems to have become their primary now that they are on 800. Most likely because its already programmed into surrounding agencies' radios.

That is a much easier conversion with all the radios in use that area!!

Yeah, 2398 is what I listen to for KPD. It's still doing the same thing. When I hear them go silent for a couple hours I scan the frequencies to search all TGs to see if I hear them anywhere else. I don't. Then later on KPD starts coming in again. I just don't get it. GCSO TG doesn't do this. It never goes silent. Rusk County SO doesn't ever go silent. Just Kilgore PD. I've been listening to KPD all day today because we are on their rotation today. My scanner worked fine from 6am until about 7pm tonight. It is now 10:40pm. KPD just called us to assist them on a call. Nothing at all has come through this scanner since about 7pm. My parents have the same scanner as I do so I borrowed theirs one day. It did the same as mine.
One thing I've noticed is that if I've had my scanner turned off for a while (a day or two) and turn it on and put it to scan KPD it works fine for hours. This always starts after several hours with them. Obviously it's nothing on their end, but I don't know what it could be on my end causing this. Like I said it did this with my parents scanner also when I tried it (Whistler 1040). It does this also when I have my scanner at work with me right in the heart of Kilgore so location isn't causing this. I'm thinking about buying a different model and trying it but I don't want to waste that money not knowing for sure.

Hello Brandon, I think the short answer might be that your scanner is not P25phase2 capable.
I used to work in Kilgore and when the Kilgore TxWARN site came online I noticed that the KPD tg volume would be "normal" sometimes but low other times. I finally noticed that the mode was changing between P25 and P25Phase2(time slots). Many TxWARN sites are Phase2 capable. I think that maybe the Kilgore site is Phase2(TDMA) by default (and KPD.radios would also have to be programmed as phase2) but the site (and all radios)switches to Phase1(FDMA) when a Phase1 mobile affiliates with it. And as long as any phase1 radio remains affiliated it won't switch back to phase2 and your scanner can pickup KPD.
The Whistler 1040 is definitely not phase2 capable. But even my phase2 capable scanners struggle to decode phase2.

I reread your previous posts and they kinda blew my theory because you were hearing KFD but not KPD. I would suggest borrowing a phase 2 capable scanner and using it side by side with yours. I'm beginning to wonder if there was a mistake made when the KPD radios were programmed?
