Thread: transmitting on both bands?

  1. #1

    Default transmitting on both bands?


    New to the ham world, just have a quick question which I can't seem to find an answer to online and can't work out why it's happening.

    I have a dual band Wouxun KG-UV9K which I've been playing with.

    When 144.500mhz is set (a) and 433.500mhz is set (b) as the alternative frequency. If I transmit on (a) 144.5 the signal bar pops up on both bands and it appears I'm transmitting on both frequencies. It doesn't do this if I change to any other 2m/70cm frequency and it does do it if I switched bands and send on (b) 433.500. I hope that makes sense!!

    Apologies if this is a simple question but I've gone through the manual, tried Google and nothing seems to come up.

    Any help is greatly appreciated!

    Hi OM James,

    It appears that the 'Cross-band Repeater' function has been enabled. Selecting f MHz on 'a' and 3f Mhz on 'b' or vice versa should be avoided, since the radio could lock up on hearing the weak third harmonic of the transmitted VHF signal.
