While on the way back from Chicago today I disconnected my 6300 and replaced it with my recently purchased my Grant XL to see how it performed. Boy what a difference there was between my RCI 6300 and Grant XL. I just recently had the RCI aligned and tuned up but...I could not believe how much better the Grant performed in recieving and noice reduction. I am now a believer in the Grant XL. I am selling the 6300 and am going to hook up either my Gray 300 or older Gray 100 with the Grant. You all were right. The Uniden Grant rocks!!!
