Probably not the squelch but the speaker on the VHF. These radios are famous for crapping out when getting wet.
Try listening to the weather radio VHF ch 01, 02, or 03. depending on your location and play with squelch.. Keep in mind they do make external speakers you can hook up.
We had the same problem with our Uniden Oceanus failing to communicate with our GPS. What the problem was, was that our VHF didn't recognize the NMEA sentences transmitted from our "ancient" GPS. We ended up buying a Standard Horizon cp180 chartplotter. PRESTO! Our DSC capability materialized.
Your 76CSx is newer than our Magellan was, so before you take on the task of a $400 chartplotter purchase, just make sure your BAUD rate is set to 4800. This adjustment alone could make your GPS work with your ICOM.
Many VHFs will not acknowledge any of the DSC functions if the unit is not receiving position data. If the unit is correctly wired to a GPS or chartplotter and you can verify that it is receiving position information, then you may have a faulty radio.
