Thread: VX-7r Volume prombems with UHF Uniden radios.

  1. #1

    Default VX-7r Volume prombems with UHF Uniden radios.


    I have a VX-7r Yeasu radio that is being used to communicate with a Australian UHF Uniden radio.

    The frequencies are in the 476.425 - 477.300 Mhz range.

    When communicating around thise frequencies, the volume on my VX-7r radio is very bad. I have the volume on max but can hardly hear it..

    If I tune it to a commercial radio station with music playing, the sound is really grate... what can the problem be?

    Hope someone out here have an idea..

    Before anyone mentions about the legality of those frequencies, I will assume you have a reason why you are allowed to TX, or are just listening.

    The reason regarding the reception could be a number of reasons, and others may have more ideas, but will list my own thoughts:-
    • Antenna, mainly designed for Amateur Radio Frequenices[/*:m:3kawwgpj]
    • Transmission you are listening to maybe in different FM to your setup (ie Narrow or Normal FM)[/*:m:3kawwgpj]
    • Could be an AM signal (Don't quote me on this, but just listing as possible idea)[/*:m:3kawwgpj]
    • Too far from Transmitting station[/*:m:3kawwgpj]

    So a few ideas, others may have more ideas.

    Hope this helps.
