    hi fella, im running a realistic pro 2032 for digi reception if thats any help, people forget that even though its a digital signal the carrier is still analog so there for the content is made up of tones in pulse form ( or to coin a fraze "a data packet" ) so all you have to do is connect audio out eg.. the speaker or tape out or headphone socket or in very modern receivers the discriminator output to a comuputer then after checking that your output from the scanner is working on both audio channels (stereo i mean) you can check this biy plugging your headphones in and if the sound is in the middle of your head then thats it, if its too one side or the other then you need to either buy or make an adapter from 3.5 mono to 3.5 stereo. what your looking for is that the audio out from the scanner is in the middle of your head (by the way dont try to fluff this connection, it shoudnt do any harm but it will badly affect the decoding accuracy)..... now conect the other end of the adapter lead to either the audio in or the microphone socket on the back of the pc (try to avoid using the microphone input on the front as this too can cuase inaccuracies in decoding. then look for software to decode what want to listen to on line (eg PDWv3.1 is a good one for pager reception and the vast majority of pager traffic seems to be available uk wide on 153.025 mhz) then follow the instructions with the software and after a bit of messing about youl get the ballance just right. as far as voice digi signals go there usualy tetra brand which is still reasonably new and so far the decode sofware is on the market yet and its usually police or government on this one so decoding it could easily bring boots to your door. theres plenty other interesting stuff out there to keep you occupied. my email is "GI3ZX@HOTMAIL.CO.UK" if your stuck give me a shout. ps the pdw software is free at source, if you want the link email me and il send it to you. jon

Hi garden stuff ok here we go.......people forget that digi is just pulsed tones on an analog transmission so to simplify it .......voice that you hear in digi is generally tetra and is used by police and some emergency services... my advice dont go there as at some point using it could bring shiny black boots to your door... on the plus side there are a wide range of frequencies that carry pager activity and theres sevseral pieces of software some of which are free or rely on donations to keep going. eg im running a realistic 2032 receiver for pager frequency linked to the computer via an audio cable and decoding it with PDWv3.1 sofware,uses very little processor power and birings me hours of entertainment and general nosyness... saves me gossiping with the nieghbours. heres my email address GI3ZX@HOTMAIL.CO.UK if you want i can give you the finer details of how to set it up. in the meen time tune into 153.025 and if you can hear a regular 2 tone broken up by what sounds like someone munching on musicle concrete your half way there. good luck have fun

Hi, i think i can help you, You will need to know about digital and analog signals.
I can guide you, but since im not there, you have to do it yourself.
To convert signals from Analog to Digital you need an (ADC).
Well it is really complex, you can read more about it here.
im sorry i wont give you a step by step solution, but as you can see other 4 experts have tried to solve this. This is complex mate, so if you really want to chnge it, go to that link and it will tell you how.

*I personaly think analog scanners are ok, and if you want a digital, its easier to buy a digital one, rather than converting it*

How to enter codes on uniden bc60xlt handheld?


Hi, first, you can only listen to analog radios on this scanner, so if you local or state public servants went to digital, you are out of luck. You can still receive National Weather Service, most railroads, ham radio operators and any small town police and fire that have remained on analog VHF and UHF. Do a Google search and you can get the instruction book for the radio. As far as channels, search for Radio Reference dot com and search for your state and county. That will list the channels to enter into your radio. Good luck and have fun.

Do I need to upgrade my Uniden Bear-Car BC 60XLT-1 30 channel programmalbe handheld scanner from analog to digital? We cannot listen to the NASCAR radios any more? We were told we needed to go digital?


NASCAR radios are not digital & besides, your scanner can't be upgraded. Try programming your local NOAA weather frequency. If you can't hear it, your scanner is not functioning properly & it's doubtful that it would be worth the cost of repairing it.

Uniden bc340crs from analog to digital


Hi Sharon -

You're not going to listen to digital transmissions on this scanner, as it will receive only analog transmissions. The only "digital" this radio offers is the display.

This is not a throw away however - this radio gets great reviews, If you live in an area that uses trunked / talk groups / digital encoding - sadly - this won't cut it. The radios that can decode those signals cost several times the cost of this scanner brand new.

Scanner monitoring is a growing hobby and there's a lot of info and help. You'll need to invest a few hours reading and asking questions to help guide you to the radio that will let you use it the way you want. One such site is ScannerMaster. Check it out & good luck!

Sorry, but the answers to your questions are no and no. Modern scanners are what they are, and they cannot be modified to monitor any secure (encrypted), digital, or cell phone communications. There is no magic fix to convert an analog scanner to digital. If you want to listen in to digital communications you'll need to purchase a digital-capable scanner, but that will still leave you without cell phone coverage or the ability to listen in to whatever secure transmissions you're referring to.

Getting a bearcat 370 scanner for christmas. we have digital and analog frequencies in our county police, will this take both?


The BC370CRS is a straight analog scanner. It will not do digital, and it will not do trunking. I use mine for fire, EMS, and aircraft. Unlike most of today's scanners, it has good coverage of both civil AND military aircraft bands. If you want a preview, you can download and print the scanner's manual, at no cost, here:

What channels for scanner


You will have to find out if your local safety systems are analog, digital, analog trunking or digital trunking, then buy the appropriate scanner. Radio Shack can at least let you know that much before you buy a unit. If they have digital trunking, only 1 or 2 models will work, and reception is quite limited.
You can also go to www. RadioReference dot Com and select Florida and your county and find out the info there. okay?

We have a uniden scanner and want to know if it can be changed from analog to digital? We are in sticker shock right now.


If it's an analogue tuner then it cannot be "converted" to digital since it is not a digital system to begin with, but you may be able to purchase an add-on digital remote tuning unit / box from a Uniden stockist.

I need to know how to program channels into it


HI again, the 248 is only a 50 channel, do you need this info for the 860? If so, I answered in your other post, but here it is again.

Hi tina33, I have an 860 scanner,and this is how I do it. If there is no freq's in there yet, start on channel 1 and punch in the freq- hit E and it will enter it into the first channel. Hit manual to go to ch 2 and repeat. If you need freq's for your area, go here and search out your state and county and it'll give you a list of freq's for your county.You do not have to add the weather channels as their in there already, just hit the weather button. I use an external antenna on mine as it extends the range and allows me to pick up the cars as well.

If you need a book for your scanner, you can get one here, just print1.gif it out.

Change from analog to digital


There are digital scanners available, but their use may be limited, depending on what you want to listen to.

A lot of scanning enthusiasts have spent a lot of money, only to discover their new digital scanner is useless.

Many emergency services are on digital BUT, they are also encrypted, so even with a digital scanner, encrypted transmissions cannot be heard.

Before parting with your cash... do some research on what digital signals can be heard in your area, keeping in mind that although some digital services are currently transmitted 'in the clear' there may be plans to encrypt them later.

Hope this helps.
