I have checked several sources, and they all show that the PRO-16A is a 16-channel VHF/UHF CRYSTAL scanner. Remove the bottom cover and you should see the crystal sockets.

Can a realistic pro 55 model 20 124 be programmed to different frequencies?

Hello, your scanner appears to be a 10 channel crystal controlled scanner. I'm estimating it to be around 30-40 years old. I think there is a couple companies still making custom crystals but you have to find the freq's #'s to give them. Here is the freq. range it will pick up. Frequency range RX 30-50 / 144-174 / 450-512 MHz I personally would take the money spent for crystals and apply it towards a newer scanner that is programmable so no crystals needed. Here's a link to some more info;

Looking for a manual for a Realistic Patrolman Pro 40 UHF/VHF Scanner. I don't even know what kind of power supply it needs.. LOL

Hi, that unit looks to be a mobile scanner and if I'm seeing right then you would need a Base power supply that could supply 12volt to it. Course you could also use a computer power supply and find the 12 volt line out on it. Here is the link to some spec's for it. Looks also to be crystal controlled so it cannot be reprogrammed. Good luck.

How to program a crystal realistic pro-54 scanner

If it is indeed a crystal controlled scanner then there is no programming involved. You have to remove a crystal and reinstall a different one with the freq. you need. There is a few places online that will still build you a new crystal/crystals. Won't be cheap, personally I'd spend the money for a new scanner. The old ones have went a little out of tune with heat and age.

How do i program this thing! I know it is almost antique.its a realistic pro-54 patrolman scanner.Do i need to take it and have crystals changed?can i do it myself?please help!!!

The Pro54 is a Radio Shack VHF/UHF crystal scanner. There is no "programming" done to this radio as it is crystal controlled.

Crystals are user changeable and are relatively inexpensive at about $8 each. Availability is declining. You can find suppliers on the internet - one such is You'll need to know the frequency of the service you wish to monitor, make sure it is in either the VHF or UHF band supported by the scanner and finally obtain & install the crystals for those frequencies into the scanner.

The down side is if you move, most if not all the crystals installed will not be in use in the new area - making them worthless to you. You would have to find an interested buyer (probably in your old own) for those specific frequencies to recover some of your original investment.

I hope this helps and good luck! Please rate my reply - thanks.

This is not my product I have a Rca four band scanner (old) model # 16S400 need a manual for programming freq

The RCA 16S400 is not a programmable scanner. Rather, it's an old (70's) crystal-based scanner that requires one crystal for each frequency. It covers the VHF-low, VHF-high, and UHF bands, and utilizes Regency type crystals. You can do a Google or Yahoo search for the crystals, but eBay is probably the best, and lowest priced source.

Need a manual to program radio freq for a RCA four band veractor tuned scanner, this is not a gps but a radio scanner model # 16S400

Please excuse me if I've already answered your question -- it sounds familiar. The RCA 16S400 is a 70's-vintage crystal based scanner that covers the VHF-Low, VHF-High, and UHF bands using frequency-specific crystals. It is not programmable, but rather requires one crystal for each frequency to be scanned/tuned. It uses Regency-type crystals which can usually be found on eBay at reasonable prices.
