    I have the portable radios that use "number codes" for lack of a
    better term. They have a large number, such as a 3, and then a small
    privacy code number. I have some old walkie-talkies that broadcast on
    a set frequency (45.something), and I want to use them together. They
    are both FM radios.

    What website would have a conversion table? Five minutes of Googling
    didn't yeild any results. A quick response would be great. I tired
    using the scan function, but it didn't find it. Thanks in advance.
     
  2. Where are you?

    They probably are FRS (Family Radio Service) transcievers. In the
    America's they use 464 mHz, in Europe, Asia and Africa, they use
    446 mHz.

    The old "walkie talkies" are probably on 49mHz, a totaly different band.

    They could also be on 27 mHz (CB) or 29mHz (29.7-29.9). If you are in
    the U.K. and they are really old, they could be 900mHz CB, which was
    "deleted" to make way for GSM "mobiles" (cell phones).

    There's also some Hi-VHF walkie talkies with limited channels used
    in the construction industry. (I don't remember if they use colors
    or numbers for the channel designation). In the 150-160 MHz range.
    Not possible to operate with the 49 MHz stuff.

  4. Find the serial number tag. It usually has the manufacturer and model
    number attached. It may be inside the battery compartment.

    If it has the FCC ID number, go to:
    <https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm>
    and punch in the grantee code and product code. The grantee code is
    the first 3 digits of the FCC ID. The product code is the remaining
    digits. The resultant pages should give you a clue as to what the
    radio can do. If it's a commerical radio, you'll probably need to get
    a license to use it.

    I seriously doubt you will be able to use them together as it appears they
    operate on totally different bands.
