HP41 code to compute satellite position from TLE/keplers?

[twdeckard]

Excellent suggestion, I skimmed thru it quickly and didn't find it.

Its specifically a program called ORBIT 1, or ORBIT two for the -cx. It was the calculator version of a BASIC program for predicting satellite look at angles from keplers you get from NORAD.

I am interested in the HP version because if you are going to try to send morse code to an antique amateur radio satellite you might as well plot its position with your '41!

Also, I only need approximate azimuth/elevation and would like to investigate the simplifications they used over the more elaborate models available in any flavor of source code desired.

I sent a note to the amateur satellite radio association to see if they have it in the archives.
