I do know on the display screen on the second line two letters (DG) WOULD APPEAR.Now the letters (VC) APPEAR...This may have nothing to do with my problem..I am lost I did Initalize and reprogram + a new (same kind) antenna...I am getting discouraged with my failing attempt to find the problem. i would like to adjust the zeromatic function currently I think it is off,...I am sorry for the long post...I AM DESPERATE ....In Advance Thank You for all the help...

Are you saying that the digital system you were listening to is now analog? DG means the scanner is decoding a digital signal and VC means the scanner is receiving an analog signal. More than likely nothing happened to the scanner something might of happened with the system you are monitoring or some type of interference has been introduced around where you are listening.

I have always experience this with the Hamilton County system. One thing to watch for is the location you are recieving from. If you are scanning from a stationary location, I would lock in on one site. I monitor Catooosa county, and if I recieve from Lookout mountain, digital breaks up alot. The system supports both digital and analog. Eastridge is still analog. The 800MHz ant. helped alot. I do however still get the crackling from Hamilton County and chattanooga PD. Note too that the Multi Site function made this worse for what I am monitoring, only because the Ringgold site is a Sub-site.

I was looking at the global PSR-500 Expert Settings Spreadsheet: PSR-500 Expert Settings

And then I ran across the GRE document: "RSP-500/600 "CPU F1.2" and "DSP U1.2" Firmware has been released" Firmware Update which says:
- Changed default "EndtoneMot" value from 250 to 80. The value 80 is used to correct squelch tails at the end of voice transmissions on narrowband EDACS systems

I think this means that the "spreadsheet" should be updated to reflect the firmware update.

That spreadsheet hasn't been updated in years.

While messing with the ARC500 program,afterwards the owner tag changed from the scancat tag (originally programmed by r/s) to "welcome psr500" even though the unit is a PRO-197. No big deal here,just an oddity.

Awsome unit so far! I'll be "dinkin" with this thing alot,lol!

It's default Global Settings Opening Message in ARC500. Change it to your name, phone and ARC file name or whatever...

Has anyone figured out what the "Noise Thresh" option does? And if original setting is 20 what does everyone else have it set at? And has anyone come up with any tweaks for digital decoding as in the audio/signal breaking up. Just curious...

Have you looked at the Easier to Read Manual?

Easier to Read Pro-106/197/PSR500/600 Digital Scanner Manual

xusmarine1979 · #29 (**permalink**) 09-01-2010, 07:21 AM

Yes I have. Have I missed where it explains what the option does?

Default value is 20. Mine is set to 45. Using scan ner menu, go to Noise Thresh: Then press FUNC SEL for description of it's use and range,

Ok. So what does it do? Does it open up the squelch for digital to help with the decoding? I've adjusted it and really haven't noticed much of a difference and just put it back to 20. It's the only setting I'm not real familiar with.

Receiver noise threshold.
"External noise appearing at the front end of a receiver, plus the noise added by the receiver itself, determines a noise threshold that has to be exceeded by the minimum discernible signal."

Scanner location may be a factor also.

So if in a noisy environment the setting needs to be set in a certain direction?

fmon · #34 (**permalink**) 09-01-2010, 10:53 AM

The value range is 1-128, could be default might be too low. I use 45 on these two 197"s at this pc plus a bedroom 197. 50 is set for mobile 600 and portable 500. I just checked a trip file for the latter two and they are also 50.

I'll give that a try. Thanks.

Here is the description from the link I sent:

Sounds like the number of noisy 'bits' that the scanner will allow prior to retuning or adjusting with the DSP. I have better results with a lower value.

The default value is 20.

Thanks Dan. I just wasn't sure exactly what it does though. Whether it simply opens it up more to decode or closes a bit to keep noise from decoding a false signal. I hope I'm describing this correctly.

Hi Jon, I can't provide any better description than the quote from the Easier to Read manual that I provided above. I have done quite a bit of searching and came up empty.

Yeah, I'm pretty much in the same boat. We'll keep trying.

Thank you Frank. i have been trying to find the best settings for digital decode on the local Moto II simulcast system. My optimum setting for decoding caused my PSR-500 to occasionally switch to a non-active channel and the audio was a warbling screech. After a few seconds the scanner would resume normal scanning. After reading your post, I turned the noise threshold up instead of down. So far everything sounds good. I was tweaking threshold in the wrong direction..
