Best rig for the price today.
CB's today pretty much give you mediocre performance, compared to their older counterparts. I had the stripped down version of this rig, the Pro510XL (Still do.), but the squelch went on it, but it was a talker and a listener. Now, I use it as a bench test rig. The Pro520XL has that added RF gain feature, which is nice to have. Out of the box the rig does 90% modulation (Because of the limiter set in it.), which is better than what 75% of the rigs out there can do. Also this rig has one of the best receive AGC setting. You can almost be next to someone keying up and they won't sound fuzzy distorted from signal overload. Also, having the ability to turn off the ANL is nice when you're parked in a quiet area and want to hear those weak, distant stations. The S/RF meter isn't bad to get use to, one LED = 1-3lbs, two LED's = 4-6lbs, three LED's = 7-9lbs, and all four LED's = +10lbs and over. We'll see how this rig holds up the test of time in my truck, but so far it's a performer.
