ok dave, guess your kc tracker had the relays built-in mine had the 
relay drivers but i had to create the relay interface.  i believe you 
are correct on the yaesu rotors, i didn't use the yaesu rotor so i 
had to create a way for the rotor data to be feed to the kc 
tracker.  i also remember qt4 and several others for the 
satellites.  i had a program called silicon emphersis or something 
like that smile.  it didn't after 2000 so that was the end of that 
program.  there was a program called the second op written by kl7grf 
and it had a satellite tracking section in it.  that was also a dos 
app.  ok dave, guess we beat this horse to death grin, take care, c u
