Title: FT-990 Memory Problem Post by: W8UJX on January 17, 2014, 01:43:44 PM When I turn the memory select knob (MEM) on my FT-990 the channel number displayed will not increment or decrement correctly. It will move from 1,2 3, back to ,2,4,5,7, back to 5 etc. The jumps are random and occur whether I am advancing or decrementing the number.
I tried cleaning the switch with DeoxIT. No improvement. Any ideas? Thanks. Jerry, W8UJX Title: Re: FT-990 Memory Problem Post by: Steve - K4HX on January 17, 2014, 02:41:12 PM Check to see if it's an optical encoder. If it is, DeOxit is of no use.
