It was a software switch on Sound Preferences. My Thinkpad has hardware switch and volume control on the keyboard, so I didn't think about the software mute! This looks like it wasn't off long, but actually it has been a couple of days -- I just didn't notice it right away! Still working on a permanent server at our courthouse EOC. It will be W5SFA or W5SFA-1? on 10.148, psk250. Maybe next week. 73, Gil WB5RFQ -- Gilbert A Franke 361 442 6008 (cell) 130 N Harris Bellville TX 77418
