I have had a strange thing happen with my O2. I have been impressed with the
sensitivity of the receivers, unlike my Pro. However, in the last day or two
the main receiver seems to have gone very deaf. However, with the pre-amp on I
receive signals strongly. It is currently 9:30pm on Friday evening and I am
listening to JARTS on 20 RTTY. With no pre-amp I can barely hear AH7C and
there is no indication of band activity on the band scope. With the pre-amp
on AH7C is registering S9 and there are a whole bunch of copyeable RTTY
signals showing strongly in the band scope. In the past the pre-amp seemed to
give me about an S unit or so of increase on the S meter. Now, it is the
difference between nothing and S9. The sub receiver appears to be hearing
about the same as the main with the pre-amp, but of course I cannot see its
signals on the band scope.
Has anyone else experienced these symptoms? Is it possible I could have had a
static discharge on one of my wire antennas zap the main RX front end and not
bother the pre-amp if it was turned off? I haven't normally used it. I am
listening with the AGC set to the minimum of .37uv.
My first thought was that the higher bands are completely dead at the bottom
of the cycle, but since I am hearing so well with the pre-amp on there appears
to be something else at play.
Any thoughts anyone - before I contact Ten Tec?
