    I had a JAPANESE FM/AM Panasonic RX-MDX7 Boom Box. Does any one know some
    tricks to make ( or modification ) it to work in USA channels / frequency

    Thanks in advance,
  2. Doubt it's possible, but you would need to look at the unit's
    service manual to know for sure.

    Your best bet is probably to just get a US-specific replacement.
  3. I don't know about AM, but the FM band is the same; should work fine.
    Have you tried it? (At least the stuff I have worked fine in Japan and in
    the US.)

  5. I thought the FM band in Japan was a smaller segment and/or started
    lower in the spectrum than in North America.

    Channel spacing, on both the AM and FM bands vary from country to country.
    So in some countries (and I don't know if it applies to Japan) the spacing
    on AM is 9KHz apart. Likewise FM has a different spacing. It means
    virtually nothing with an analog tuner, but with digitally tuned radios,
    it can mean most stations can't be tuned in. Also, the spacing difference
    may not be noticeable on FM. In North America, FM channels are 200KHz
    apart, but the spacing elsewhere is different. But if the radio tunes
    every 100KHz, like one I had, one will not notice if you are in North
    America or elsewhere, but that smaller increment works on both schemes.
