Hi All:
I have a strange problem with my OII. When I power it up it works as
advertised. Both the main and sub-receivers operate normally. After a short
time (minutes to an hour) the main receiver suddenly becomes almost deaf as
if someone had thrown 30 db of attenuation into the signal path. I can only
hear the strongest signals that I see on the band scope, and they sound very
weak. When this happens the S-meter goes to 0 and never moves even though
the band scope is showing that the signal is very powerful. Throughout all
this the sub-receiver continues to function normally.
While the main receiver was working I quickly fed it 1uV and 50uV at 14.060
from an Elecraft XG-1 signai source. The main receiver heard the 1uV well,
but showed no meter movement. with the 50uV the receiver showed S7-8. The
sub-receiver with its bar-graph signal strength display showed full scale.
When the main receiver went quiet the sub-receiver still showed full scale.
The main receiver could barely hear the 50uV, and couldn't hear the 1uV at
all.
This all happened while running 2.039. I have reloaded 2.039, done a master
reset, a battery reset, and even opended the rig and removed the battery.
The behavior also happens with 2.034.
Any ideas before she makes that trip to Tenn?
By the way while I was pulling the cover, I noticed a sticker on the back
showing a garbage can with an X through it. Glad they told me. I was already
half-way to the door to throw the Orion away.
