Last evening my Thunderbolt was losing satellites until
none were reported usable. At the same time the
K5FX Thunderbolt was down to one or no usable birds.
This afternoon I dug out my other thunderbolt, the first
one I got. That one had a defective OCXO which I replaced
with a 49422. That couldn't get any usable birds either.
Now things are back to normal. K5FX is happy and so
are both of my Thunderbolts.
So -- What happened? Anyone else notice something
out of the ordinary? Someone practicing GPS jamming?
BTW Is there a spot on the Thunderbolt where I can
sample the RF or IF to feed a spectrum analyzer? The signal
coming down the coax is too weak to see on my
analyzers.
The local problem appears to be a corroded F Connector.
