For some reason, one of my 940's is deaf on 160/80/20/17. It transmits fine on all bands and hears fine on all the other bands except those mentioned above. I have not pulled it apart yet. Anyone encountered something like this before? Any thoughts where I should look first??? cheers, Paul - VA7NT ex VE7CQK - email: [email protected] "Those who hear not the music. . . think the dancers mad."
