[amsat-bb] Fox Delta ST2 interface problem

[Douglas Phelps]

I use a Fox Delta Interface, with Sat PC 32< with no problems.  The degree readout never changes even 1 degree.  Since mine works, it must be something in your hardware.  I would check the Azmuth and Elevation Pots and use a contact cleaner on them.  I would then check to make sure mu cables are not intermittent.  Mine has worked perfectly for 3 years so I think the problem has to be one of the above.

Also possible is a cold solder joint, in the Fox Delta, where the Pot lines connect.
