    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.

Radio Shack just released an upgrade for the Pro-96 which aims to:

Improve digital decoding of weak or distorted digital signals
The enhancements that were made to the digital decoder to provide improved
digital performance on systems like the Detroit Project 25 system also provide
noticeable decoding improvement on all supported digital system types in areas
with weak digital signals, or digital signals that are distorted due to
multipath or simulcast .
I’ve read at least one side-by-side comparison of the newly-flashed Pro-96 vs, a BCD396T which was described as “phenomenal” in favor of the Pro-96.

From the Radio Shack scanners forum:

“Not even close... A good 1/3rd of the transmissions I heard on the "new" Pro96 had either nothing at all on the 396, or the talkgroup would flash but nothing heard. Another third both received but the 396 was more chop than audio. The last third they were both the same….I just finished testing extensively in Monroe Co and the side-by-side was phenomenally in favor of the Pro96. Also spent an hour in Flint and it rocked there too...”
Anything similar on-deck from Uniden for the BCD396T and BCD996T? It sure might help on the 5 site P25 simulcast system I listen to regularly.

UPMan should be aware of this by now and will probably pass this on. I wouldn't expect anything (if at all) for a few months.

I'm happy that GRE has addressed concerns about the PRO-96 and CQPSK for some in the Detroit area and some in Ohio. I've updated my PRO-96 DSP to 1.3, but live in an area that does not use CQPSK. To me it's not worth the extra encrypted noise I get from the PRO-96 from encrypted talkgroups that the 396 and 996 block out, with the exception of the first 2 microseconds of an encrypted comm.

So far, I've not heard anything on the 96 that the 396 or 996 is missing between comms with the exception of scanning other systems. If I need to listen to just specific talkgroups I can hold on a particular system or scan specific talkgroups. The digital voice sounds just fine with the current settings I'm using in the 396 with no noticable difference to the patched PRO-96 DSP, but as always YMMV. +;-)

However, the PRO-96 will do something the Uniden's can't. You can run PRO96COM to visually display activity on a P25 system without modifing the radio for baseband audio out.

"Some" in Detroit? Check your atlas again - Detroit isn't just a small burb ;> It also affects Cincinnati, Flint, Monroe, Australia, and many more.

"The digital voice sounds just fine with the current settings I'm using in the 396 with no noticable difference to the patched PRO-96 DSP, but as always YMMV"

Of course it does - you aren't listening to CQPSK. This is a patch to fix CQPSK, and now the Pro96 is clearly the leader in those areas.

Can't argue with that, Rob. You've obvously done your homework and can support your opinion. Enjoy!

Dave, the update also addresses weak distorted signals on all supported digital system types. So if you are getting good reception you won't notice any difference. I still need to get a dedicated 800mz mobile antenna for my apartment. The 800mhz antenna from RS barely brings in the signal and i'll have to say that with the upgrade I am hearing more transmissions. My 396t sits quiet. If I walk outside the reception improves dramatically and the 396t and Pro-96 act the same. I am monitoring a MOT Type II P25 anolog mixed system.

Where do you see that John? As Lou Magg pointed out, I don't see any oficial release from Radio Shack included with the installation instructions, or otherwise, that tells us what the 1.3 DSP improves, unless you and Rob know something we don't.

Now it looks to me, from the previous posts, like it does more than just CQPSK, but I can't really tell the difference with even a marginal signal this morning.

I'd like to see something official from Radio Shack/GRE on what the update exactly is other than what someone thinks it does.

So far, I have yet to see anything that needs improvement from Uniden on the P25 digital voice because of the PRO-96 DSP 1.3 patch, but I don't live near any of those areas that Rob has tested in (like Cincinnati or Australia).

From my view, the many reports of remarkable improvements with CQPSK scattered around the world is sufficient to convince me that this is the reason for the upgrade. Now, if that is its purpose, can GRE/RS prevent improvements in other P25 decoding with this upgrade? I think not.

How about the RS file that describes the patch? Which says exactly what I said?

There is no RS file in the 1.3 DSP upgrade, only the one in the 1.2 upgrade, unless you have something else?

Never mind, I'm done.

And this is found where, and why didn't you just post this to begin with?? It really belongs in the original thread in the Radio Shack forum, anyway.
