Is there a site where one can FTP the lastest (most up to date) element
tables? Can they be FTP'ed direct from NASA?

I worked the shuttle with a 1/4wave vertical and a ft470 handheld
running into a 70w linear with GaAsFET preamp. The antenna is mounted on
the gutter and I am surrounded by large trees and buildings :-(. However
I rxed the shuttle at full scale for most of the passes.
There is one major difference between our operating enviroments, In my
The most I would have to compete against on a pass would be about 15
stations.
In fact when I worked Martin KC5AXA a few days ago there was only my
self and one other station!.
The only need for high power is to be on top of the dog pile.

The most current orbital elements from the NORAD two-line element sets are
carried on the Celestial BBS, (513) 427-0674, and are updated daily (when
possible). Documentation and tracking software are also available on this
system. As a service to the satellite user community, the most current
elements for the current shuttle mission are provided below. The Celestial
BBS may be accessed 24 hours/day at 300, 1200, 2400, 4800, or 9600 bps using
8 data bits, 1 stop bit, no parity.
Element sets (also updated daily), shuttle elements, and some documentation
and software are also available via anonymous ftp from archive.afit.af.mil
(129.92.1.66) in the directory pub/space.

This kind of equipment will work in the US too -- I made a packet
contact with the shuttle this morning with 50 watts and a scanner
(discone) antenna on the roof.

I don't quite understand the above statement. The shuttle has quite
a view (usually) on the ground. How come only 15 stations?
