I have had recent experience with 3 different 50x1s with the same problem. Even right out of the box, no extra programming at all, reception blocked unless squelch is set to 0. One radio worked for a short time but then required 0 squelch. We combed through the menus to see if anything was obviously set wrong. One thing seems a little confusing, and that is Menus 18 and 19. There is an "off" choice for Optional Signaling- menu 18, but no "off" choice for 19. Out of the box, QT is set in 19, which indicates a required tone. I'm away from the radio now, but could setting Menu 19 to "OR" and 18 to "OFF" work? We'll give that a try when we're able. A comment from BTech would be helpful here, hint hint...
