How close is the Orbit rotator to the Alliance U-110? Norm's Rotor Service has new-in-box U-110 units. 73, Jim KQ6EA

Hi Tony and the list
I also use the excellent InstanTrack software. Runs fine on an ancient laptop discarded by my
employer.
Didn't know about the option to use the
parallel"printer" port on old PC's.
Is that the way to do rotator control and Doppler
at the same time.
Serial port to the CAT port on the radio - doing
this already
Parallel port to the rotator control box - would
like to do this
What would the command line look like in the .cfg
file
Hi John,
Yes, you can do doppler and rotor control at the same time on a typical old laptop by using the serial port for CAT and the LPT port for rotor control.
InstantTrack can work with any software that supports the Kansas City Tracker interface. You can download the parallel port driver software for FODTRACK and the WB5IPM Controller from the AMSAT Software archive for free at:

There are probably a few other as well.
My own favorite is the iRotor driver for the Orbit 360 rotors but of course I may be a bit biased! The software and article about building the interface can be downloaded from here:

Sadly, Orbit360s have become harder to find these days but perhaps there are other cheap TV antenna rotators that could be used.
