Hi Alan, 

It is lookin better with your corrected TLE.

Our ground software uses a combination of pyorbital and ephem libraries in python. All of the ephem software works with the new TLE, but we're having an odd issue with the TLE with pyorbital. 

I'm not sure if you're familiar with python or the library, but the error is below: 

 self.orbit = int(self._line2[63:68])
ValueError: invalid literal for int() with base 10: '4   0'

But it seems to be having issues with the second line at the last segment, highlighted below:  

RadFxSat-2
1 99995U  00000   21017.85640046  .00000000  00000-0  10000-4 0    03
2 99995  60.6849  134.0000 0012810 280.8458  55.7744 15.21152014   05

Every other TLE we've tried seems to work just fine, even for other satellites and ISS. So any advice or help is greatly appreciated.

Sincerely,
Rizwan Merchant

Let me know if they work for you.  Also, make certain that both data lines are the same length when you put them into the file for your tracking program.  Sometimes due to the font and standards conversion, extra spaces get added.
