Hi, For those who own a Z-11 or AT-11MP autotuner by LDG, there is a new processor available that adds 200 memories to the tuner along with a couple other enhancements. http://www.ldgelectronics.com/mem_upgrade.html This may be old news, but I just ran across it and thought I would pass it on since many on this list use LDG tuners... 73 Tim NZ8J
