Not sure if it's the radios, the users, or what, but fortunately it's not too common. Has a way of catching you off guard...
Quick question - curious if you're locking out encrypted TG's on your Uniden's? I'm debating because occasionally I'll hear stuff in the clear. But it's at the expense of slower scan speeds. Sometimes they can sit on these TG's for upwards of 5+ seconds, and that's a long time. I can do it either way, just curious what others with Uniden's might be doing.
