The Pro-2052 radio scanner from Radio Shack....  Ever since I purchased my unit I noticed that there was little support on the internet as far as modifications go and detailed information on its internal workings.

   So here it is, my web page on the Pro-2052.... Although I will still be working on different things for this scanner I can't always respond to all inquires asking for specific modifications let alone guarantee that I can accomplish a requested modification. What you find here is what I or

other people have accomplished so far. The information provided below such as the service manual is there for a reason. If I don't have time nor the experience to help you out with a modification then it will be left in your hands. Sorry, that's the way it goes sometimes. But don't hesitate to email me about your questions, comments, concerns or modifications as I may be able to help you and also have your mods/info posted for everyone to know about. In fact, when you request a mod that I can't do or don't have the time to accomplish it will be put it in the Wish List. Putting it there may grab the attention of others who will do it themselves and be kind enough to send in the instructions!! If you do happen to have modifications and want to create instructions you may want to use these photographic scans of the PCB board to help aid you in creating an easy-to-follow pictorial diagram.

Come join George's discussion board
specifically about the Pro-2052.
Thanks George!!

If you own the Pro-94 you can now program it using a computer. Doing so requires the same method as the Pro-2052 when directly accessing the EEPROM but unlike the Pro-2052 the EEPROM in the Pro-94 is much easier to access. You can download the details here.

I use this to run and create a list of  talk groups. It is more of a control window, I do not believe it uploads or downloads. My one hint to the novice, make sure you get the port and cables working correctly before putting a lot of effort into testing the software otherwise you may end up blaming the software for what actually is a hardware problem.

MDTmonprog.zip - FREEWARE (MS Windows) - Decodes 4800bps Mobile Data Transmitters, using the line input on a soundcard or a serial port data slicer, that various services use for remote computer links. Note: The soundcard is more reliable for decoding. Also, be sure to use the FM discriminator output. WARNING!! Decoding of Police Department computers is unlawful!!
(Audio sample - MDT)

PDW110f.zip - FREEWARE (MS Windows) - Decodes POCSAG & FLEX pagers, ACARS packets from airplanes, MOBITEX data terminals and ERMES using the line input on a soundcard or a serial port data slicer. Note: The soundcard is more reliable for decoding. Also, when decoding ACARS be sure to use the AM discriminator output for reliable decoding. When decoding the other protocols use the FM discriminator output.

SpeechInverter.zip - FREEWARE (MS WIndows) - Inverts scrambled audio that sounds like Donald Duck using the line input on a soundcard in full duplex mode. Note: Best used with the line output modification.
(Audio sample - Speech Inversion)

Trunker - FREEWARE (MS-DOS) - Decodes Motorola trunking data using a serial port data slicer. This is great for finding frequencies allocated to a trunking system. Better details can be found at http://www.trunkedradio.net along with a schematic for a serial port data slicer.
(Audio Sample - Mtrunk)

Etrunker - FREEWARE (MS-DOS) - Decodes EDACS trunking data using a serial port data slicer. This is great for finding frequencies allocated to a trunking system. Better details can be found at http://www.trunkedradio.net along with a schematic for a serial port data slicer.
(Audio Sample - Etrunk)

WinAPRS 60 meg - SHAREWARE (MS Windows) - Decodes Automatic Position Reporting System data by using the soundcard and plots it on a map. This system is mainly used by Ham Radio operators to send out their location using GPS data. They also send out weather data, text messaging and other such information. To use this software with the soundcard you must install AGWPE which is freeware. For more details on using AGWPE read some documentation on it. Note: Be sure to use the FM discriminator output. Also, the most widely used frequency in the United States for APRS is 144.3900 MHz FM.
(Audio Sample - APRS)

ATCS Monitor - FREEWARE (MS Windows) - Decodes Advanced Train Control System data to monitor railroad track switching and other related tasks using the line input on a soundcard or serial port data slicer. Note: The soundcard is more reliable for decoding. Also, be sure to use the FM discriminator output.
(Audio Sample - ATCS)

WinTone - SHAREWARE (MS Windows) - Decodes DTMF, CTCSS and other such tones using the line input on a soundcard. Note: Best used with the line output modification.
(Audio Sample - DMTF)

ScanREC - FREEWARE (MS Windows) - VOX recorder. It automaticlly records audio using the line input on a soundcard. Note: This is best used with the line output modification.

WARNING!! Use of the software listed above is done so at your own risk! The decoding of certain radio signals that you do not have lawful access to can result in fines and/or jail time. You have been warned!!

WXsat -FREEWARE (MS Windows) - Decodes signals in the APT format from NOAA, Meteor, Okean, Resurs, Meteosat and GOES Satellites (AM) using a Soundcard. WXSat can also decode FM-Fax for facsimile signals transmitting via shortwave. Note: Since the Pro-2052 does not provide the available bandwidth needed for reception of these signals all results will not be 100%. However, you can receive enough of a picture to get an idea as to how fun this is!! Be sure to use the FM discriminator output. The satellites you can tune into with the Pro-2052 will be the NOAA type. To track the satellites and to know when they will be passing over your area download SatScape which is freeware. Once SatScape is configured you can find out what frequencies to tune into by clicking on the satellite. Although you can pick up the NOAA satellites with a simple dipole antenna it is recommended that you use something much better. I have personally used a Radio Shack discone antenna about 35 feet in the air with decent results but this is not being recommended to use. For more information visit http://www.hffax.de
