    I have a 991a and for some reason the audio doesn't work on 70cm and 2m. HF audio is fine but not on those 2 bands. I've tried plugging in headphones and still nothing. I can see signals coming in and can hear them on my HT but not on the 991a.

    Any idea what might be wrong? I'm just using a gp-1 antenna directly connected to the radio...signal looks strong on the waterfall but no audio at all.

    Look in the F Menu settings if you acidentally don't have the tone/dcs switched on in recieve.
    Then the receiver is waiting for a digital tone to open the receiver, if that is not there it won't open audio.
    Check with going through the menu and see if pushing SQL OFF gives audio.
    IF so, put TONE/DCS on offf for receive.
    Normal squelch will work then.

    Thank you! Turning off the tone seems to have worked. It was on ctss before and it works when its off and when it is on d.enc

    Bummer, that, isn't it? I spent something like 15 minutes at the weekend wondering exactly the same before I checked what should have been obvious!
