Subject: [TenTec] Jupiter display noise?
Howdy,
Recently my 3 yr old Jupe has developed an annoying rapid motorboating
noise in the background audio.This noise starts at 18mhz and seems to peak
at 21.357mhz.At first I thought it was external to the set,but it occurs
in dummy load also.Depressing the menu button eliminates it completly and
it can be made to occur while in menu by moving the tuning knob to
highlite the menu items.The speed of this noise varies directly with knob
speed.Returning to normal operation reinitiates the noise(sort of like
"running rabbits"on a radar screen.)Anybody have any ideas what's causing
this?
