Hi All, Audio gain knob on the front panel doesn't completely reduce the volume to zero. It works fine in normal use, I can balance the level of audio easily. But when I want to leave the radio in RX but turn volume down to zero to concentrate on something else then I can still hear it. Which is distracting. I have the latest firmware installed, The problem is both with internal loudspeaker and headphones. I can hear the RX audio as well as button press beeps. Looking inside at the front panel circuit board, the potentiometer appears to be cleanly flow-soldered on. I was hoping/expecting a bad solder joint here but it looks and measures fine. I've read through the technical supplement to see if I can find an alignment for this but can't see it there. Anyone able to help? Thanks, Paul PS Let me know if this is the wrong forum!
