Question about Radio Communications
Works perfectly while receiving until after half hour or so then high frequency buzzing noise interferences with audio?
There is a problem with something breaking down in power supply side. It could be a filter capacitor or a semiconductor.

SOURCE: Radio scanner not receiving
The Realistic Pro-2025 relies on a quartz lock-loop signal synthesizer to receive signals, the synthesizer might of gone bad, chalk it up to old age. The Realistic PRO (Progressive Receiving Occilator) models are not around anymore, they went obsolete years ago. It's nice that you have one, they are worth some money on eBay. However I'm afraid it will cost you more money to fix the synthesizer than the radio is actually worth. It would be best to use your Radio Shack PRO-49. Realistic is a division of Radio Shack founded by Tandy Corp, basically you've been using a Radio Shack scanner the whole time. So if you have any complaints, take it up with them, you won't find Realistic anymore.
Hope this helps!

SOURCE: NO SQUELCH
I have a Radio Shack Pro 97 Scanner that I received as a present 1-1/2 years ago. It was working just fine and then suddenly there was no squelch or volume. The keys make noise when pushed, but there is no sound for the squelch or volume. The scanner scans the frequencies but does not stop and play. I went on line and found that other people were having the same problems. I went back to the store that the unit was purchased from and received no help what so ever, they said it’ s off warranty and I was out of luck, nice way to do business??. I think that something that cost as much as this should not be junk after a short period of time. I hope you can help me with this problem I do like radio shack, but I can’t afford to buy items that don’t stand up.

The Realistic PRO-2052 is an old (vintage) scanner receiver with fixed
AM and FM modes on the bands it cover, as specified by the U.S. band
allocation. The PRO-2020 covers only the VHF and UHF frequencies and
modes AM and FM is not user selectable. Frequencies can be programmed
into any of the 20 memory channels
U.S. Coverage: (varies from state to state and other countries. We don't use 30-50 Mhz here in the Philippines for 2 way mobile communications, except for cordless phones)
30-50 Mhz Lower VHF at FM narrowband only (covers mobile, emergencies, businesses, etc. and
108-136 Mhz Aircraft band at AM narrowband only
138-174 Mhz Amateur and Commercial band at FM narrowband only (2 meter band)
410-512 MHz Amateur and Commercial band at FM narrowband only (70 cm band)
If you're trying to select AM or FM for a specified frequency, I'm afraid you can't do that as it is not selectable.
If you are trying to program AM Broadcast frequencies (mediumwave (MW) or FM Broadcast frequencies (FM radio stations), those were not covered by your PRO-2020's microprocessor. Even if you modify your scanner to receive those bands, you will not hear radio transmission properly since the receiver do not decode FM wideband, which is the standard mode for FM broadcast and Television band.

Try a master reset. You will lose all of your current programming but it resets the unit back to its original state when you purchased it. here are the directions from page 53 in your manual.
Resetting the Scanner
If the scanner's display locks up or stops operating
properly, you might need to reset the scanner.
Caution: This procedure clears all the information
you have stored in the scanner. Before you reset the
scanner, try turning it off and on to see if it begins
working properly. Reset the scanner only when you
are sure it is not working properly.
1. Turn off the scanner.
2. While holding down 2, 9, and Hold, turn on the
scanner. It takes about 3 seconds to initialize
and CLEAr appears.
