    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation.

I'm having an intermittent problem decoding digital modulation on my R/S Pro-2096. The trunked system (Greensboro/Guilford Co., North Carolina) has some digital channels but isn't a full APCO-25 system. Signals are very strong at my location. But sometimes I'll turn the scanner on and just hear the non-decoded digital signals on the digital channels. Other times it will work fine. I don't have the problem with my PRO-96 handheld scanner or the BC996. It was programmed with Win 96 using information from radioreference.com.

Does anyone have any ideas.

Thanks,

I have the same problem with my pro-96 habheld. Sometimes it will decode fine, other times it is horrible. I never know what kind of reception I am going to get from one day to the next or one hour to the next. Not sure what to do. I'm thinking about getting a PSR 500 and trying that route.

I had the exact same issue with my 96 monitoring a P25 system. I returned it...bought a PSR500...all issues solved. Great reception...no motorboating...no monkey chatter...

I think my next radio will be a PSR500. Another issue I have with anything digital is once a digital transmition has completed, if another channel is talking at the same time I'll pick up that channel as well. It's quite annoying if the other channel is encrypted.

Can anyone NOT READ??? SCROLL UP to the second message in this thread, also Check BNC connection inside teh radio, 3) and check programming again?. last but not least try having RS check out the radio themselves???

What I'm thinking is it's a simulcasting system and he may be recieving more than one tower at a time. My county's system is simulcast, I have the same problems he has. But on the state's MARCS system when I am only listening to a single site it seems to sound perfect all the time. Did I say all of that right?

Radio Shack should issue a v1.5 firmware upgrade!

Hi Jon, yep, same problem in NW Ohio - MARCS digital (3600B) single tower works okay, but the multicast / simulcast system in Lucas County makes me want to leave my PRO-96 on a set of railroad tracks. I'm on my 3rd different antenna configuration (yagi pointed to only 1 tower) and still breaking-up audio, buzzing, monkeychatter. Lucky if you get the whole conversation before it crashes and burn.
Radio works fine for everything BUT the CQPSK multicast P.O.S. systems.

We have the same problem with the PRO-(20)96 radios decoding digital transmissions on the new Charleston Co. simulcast p25 system in South Carolina, also a simulcast system. I posted a question not long ago asking for comments from folks monitoring similar systems in other places what radios have the best success with digital audio on simulcast systems. Some folks say the PSR-500 and 600 are better, and I'll likely be replacing my PRO-96 with a PSR-500 pretty soon because of that. I welcome others comments on their success (or failure) decoding simulcast systems with other radios.

My 96 does the same thing on Illinois' new Starcom21 system. When I get away from Cook County's simulcast site and into areas only using one tower it works fine. The 96 definitely chokes on simulcast systems. The only way it'll ever be corrected will be with a DSP update. And I somehow doubt Rat Shack will be doing that anytime soon. When I get the money, I'm going for a PSR500 which will cover the 700mhz portions of Starcom.

I suggest we all write a letter to RatShack HQ and ask them for one last DSP firmware upgrade; hopefully enough of us bugging them will get one last gasp out of them to help us out.

It was the Lucas County P25 system that made me return my 96. I had all the same nonsense...monkey chatter, motor boating....impossible to enjoy.

I have posted something like this in the Uniden Forum. I've been messing around with my pro 96 for the last few days. What I started doing is I leave the squelch fully open (when stopped on a channel you'll hear that annoying sound). I'm sure it still has the problem on simulcast, but it doesn't get all garbled up like it did before. The only thing is, if you are listening to anything conventional make sure to use the proper pl or dpl tones so it wont stop on that channel.

So far, it seems to be doing great, especially inside the buildings. The only negative I have is that it seems to take longer to scan the banks and it will pick up the weaker signals. But if anyone else wants to give it a try, let me know how it works for you.

The CQPSK simulcast systems are not P.O.S. systems, they work great for the users. The problem is the digital processors in the scanners. It sounds like GRE has put better digital processors in the psr500 and 600. The bad thing is I don't think a firmware update will help that much on the pro96 and 2096, it's just not as good of a digital processor.

Old Problem I found in 2005

I got rid of mine for the DPL issue. RS serviced the radio, I did firmware upgrades and I attempted every tweak known.

I Replaced the radio with a BCd996T. No DPL issues since and I can pick up Private Calls as a group on APCO Motorola systems. I did like the trunking audio on the 2096 and the radio was a bit more sensative but the intermittant DPL conversations drove me nuts (usually high pitched voiced or sirens in backround clipped the message.
