A well-controlled applicator is the DeoxIT D100L-25C Needle
Dispenser. It will allow a fraction of a drop to be applied to any
surface.

Intermittency issues are not unusual with these radios and radios
of this age. Time for a connector cleaning to restore life for
another 10 to 20 years. Please just clean the connectors and
DO NOT spray anything into the radio.

Thank you all for the quick answers!
This evening when back home, I was ready to open covers and take
a look inside the Orion, but before doing that, I switched it on
and, with my surprise, the noise heard from the speaker was
different. So, after having set the correct display contrast, I
tried to listen to the 20m band it was busy! Then, I tried change
the band, mode, transmission... the Orion seems fully alive
again! Nothing has been changed from yesterday, but today it
works. Since I don't believe in miracles, I wonder what went on?
I'll check it in every function, but it seems fine.

Enzo,
My Orion-II had exactly the same symptoms, on a couple of
occasions. The master resets helped for a while, then the same
problem came back. Looking at the DC power cable connector, it
was fine. So, I opened it up.
The first thing I did was to replace ALL the electrolytic
capacitors on the A9 power supply board with high-quality 105C
capacitors. I then checked both batteries (CPU & AT), and
replaced them. The last thing I did was to DeOxit ALL connectors
in the radio (quite a job). It has never had a problem since.

Hallo everyone,
I'm a happy owner of a Orion since 2005. Today, while it was
transmitting my home energy was suddenly interrupted. After
switching the RTX on, it started behaving in a strange way:
both VFO seems ok but no band reception; only the buttons
around the display are active, the others don't work; no
transmission. I performed a Master Reset and then a Ram Clear
(followed by a master reset). Now it switch on, the volume goes
up an down, some noise comes out from the speaker, but the 20m
are silent, only electronic noise.
Is there any clue to bring it alive again?
Thanks and 73 de IK3SWB, Enzo.
