[Premium-Rx] RF-590A Display

[Ahmet Gundes]

Hi everybody,
Many postings on the RF590A Display related problems and
fixes.
Did anyone ever notice any noise during reception, like a
heterodyne,
especially with strong signals ?  If so, this is caused by
the display high
voltage driver unit and the noise leaks into the entire
system via -15V
bus.  I was able to fix it.  If interested I can give
details.
