[amsat-bb] LVB tracker noise

[joe barkley]

I am using and LVB tracker to control my GS5400B AZ/EL system.
I mainly use it on EME and WSJT controlling it with NOVA. There has 
always been excessive noise
shown on the waterfall when I am on certain 144mhz frequencies. I can cut
power to the 5400 and it goes away so I am pretty sure it is either
the box itself or the USB connection. I have put toroids on the cable ends.
I have also tried different computers and it is the same. Any ideas on 
what I could do
to remedy this.  I can cut power to the rotor and all is fine. But the I 
have
to restart NOVA each time. I could live with it if I could just switch
the Rotor control off and on without restarted NOVA etc..

Thanks
Joe
