Sorry, can't help with your request but I just had to say what an
interesting little project.
I will remember many of the early BASIC programs for tracking satellites
which appeared in a variety of the amateur radio publications in the
80's. There was one in the AMSAT journal of that era as well (by Tom
Clark W3IWI I seem to recall). I spent much time typing in and debugging
that program on a several different platforms including the Commodore
PET, Radio Shack TRS80 and my Heathkit H8 and H11. I no longer have a
HP41CX but I do have several TI calculators including the TI84+ and
NSPIRE(s) and a HP48G. The TI84+ and the TI83+ it replaced are
programmable in a dialect of BASIC and can interface with through a
simple port and have more processing power and ram that those old 8 bit
computers that I mentioned above. Now you've got me thinking that I
should give something like a try too.
Good luck with your project.
cheers, Graham ve3gtc

This will not advance the state of the art in space communication but the fact that I can command my arduino antenna rotor project from my 1983 calculator over an IL loop while recording the contacts on a old reel-to-reel would satisfy my hidden luddite tendencies.
