If the data were complete and kept reasonably up-to-date (new launches added
and dead birds removed within a few days), this would be EXCELLENT. I'm all
for it. Would be nice to throw a script together to update the Predict DB and
sat list automatically on each startup...

Hi Gary,
Let me put in a blatant plug but you might add to the list:

for LNA's, and downconveters with low frequency IF for use with SDR's
(and other VHF/microwave goodies)

Joseph,
I for one would like to see RSS available. It is rapidly becoming my
favorite way to keep track of areas of interest in something like real time.

Hi folks,
I just noticed a problem with my Yaesu FT-736R rig. Everything seems to work
fine in FM mode (both FM and FM-N), but when I switch the receiver to any
other mode (SSB or CW) the S-meter immediately jumps to about S9+50 - not
quite pegged - and I hear a full-quieting-but-no-audio sort of sound from the
speaker. This happens on any band - 2m, 70cm, or 23cm, and anywhere in the
band. If I tune to an active repeater and switch to SSB, I can tell that the
FM signal is still there, but being swamped by something.
It's got to be an internal problem, but where to start? Any ideas?
Greg KO6TH
