Thanks Paul.  I had forgotten about nasawash.
But it did not help with these sets because it requires a valid checksum 
and these have no checksum byte at all.  Of course adding an arbitrary 
byte for the checksum does not help.

How about one that reads in tle's without regard to checksums and 
creates AMSAT format. Then creates TLEs from the AMSAT format. Perhaps 
that would clean them up. . .

Or something that reads a TLE and creates a valid checksum'd output. . .
