I am a new 990 owner...
Has anyone experienced any problem with the am tuning when its tune to the lowest setting (520KHZ) and try to manually tune up or down?
With my unit, when it reaches 520, I cannot manually tune...only by entering a memory preset or direct entry.

Does anyone have the issue of losing tuner presets if the units is unplugged from the ac source for 5 minutes or more. Talking with Outlaw, they say the memory is in non-volatile memory and should not be loss...my unit loses it memory!

No problems loosing FM presets. I have not tried AM at all.
