>I'm a newbie and I tried the demo version of SatSpy 2.  It worked great
for me.  I'm impressed also because I work with a team of programmers
(i'm the tech writer) and I know how much time it takes to create a
windows program like SatSpy.  OTOH, SatSpy is the only tracking program
that I've used.<

SatSpy has a very nice graphical interface, actually the best I have come
across. But the program isn't without problems, most of which I have discussed
with the author. Here are a few:

- In countries with date/time conventions different from the US, strange
  effects can happen;
- The checksum algorithm is different from what is generally accepted, due to
  the way the plus (+) sign is accounted for;
- The program doesn't accept TLE files with only one satellite.
- If a TLE file contains satellites with different names but the same COSPAR
  identifier, the program will only accept the FIRST entry.

The program will disable itself after the 30-day evaluation period. In the
interest of the author, I will not disclose here how that's being done and
how it can be circumvented.

If the few bugs mentioned above and perhaps some others not yet discovered
were corrected, it would certainly be one of the finest programs available
for satellite tracking.
