The answer is NO. Some Older scanner models, built before 1994, were able to be frequency "modified, or Restored" to hear the older obsolete "analog" cell signals. All the Current New scanner models sold in the USA, by law, have the cellular Frequencies Permenently Deleted from their Internal chips, They aren't "hidden" in there, so they can't be "restored or modified", & these older modified, or "export" models were receving only the now obsolete "analog" phone signals. ( Older Scanners that could be "modified", were actually being "UN-modified", as they were built with these frequencies, & then "blocked").

Also, Remember, since ALL newer cellphones are iDEN, CDMA, LTE or GSM "Digital", even these older, or export model cellular frequency-capable scanners simply can't "hear" any of the current Digital cellphones, even if tuned to their frequencies.

Hope that helps.

Go to to download a PDF version of the user manual. No, you can't pickup cell phones. Be careful it is illeagle to listen to cell phones or encrypted communications.

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.

Want to no how to program scanner to pick up phone calls. radioshack-pro/95 dual-trunking.

Sorry, but it can't be done, for at least two reasons. Cellular bands are out of the tuning range of your scanner, and it cannot be modified to receive the cellular frequencies. Virtually all cellular signals are now digital, and the PRO-95 is an analog-only scanner.

Will this unit pick up cell phone and cordless phone conversations?

Sorry, but you are out of luck on both counts. It's against federal law to manufacture a scanner that will receive cellular phone calls, and modern scanners cannot be modified to do so. Plus that, virtually all cell phone conversations are now digital, and your scanner processes analog signals only. Most cordless phones operate at frequencies above 2GHz, and the BC60XLT maximum is just 512MHz.

You cannot pick up cell phone conversations on your scanner. Federal law prohibits the manufacture and sale of scanners capable of receiving cellular bands, and modern scanners cannot be modified to include those frequencies Sorry. . . .

How to pick up cell phone frequencies on scanner.

I had a scanner with 800mhz .. programed it to scan from 900.000
to 800.000 .. between those freqs. ..found several calls ... from cell phones .. but that was not what I was looking for ... I just ran into it by accident.

Police Officers ...from all agencies .. monitor cell phones .. all the time so if it illegal for citizens to do it , it should be for them also but I under the impression judges turn a blind eye to that fact.

To get celluar frequencies on bc350c 800mhz 100 channel scanner.


You can no longer listen to cell phones with police scanners as all cell phones are now digital. Years ago when cell phones were using the 800mhz band it was possible. But only with select older models of scanners such as the BC-200XLT and after an internal modification to allow tuning of 860-880 mhz range. I do believe there is equipment out there that can listen to digital cell phones but its very expensive ($10,000) and only for law enforcement use. Hope this answers your question.
