[QUOTE="SST12, post: 605424, member: 234978"] Hi All After retiring my trusty old AD3000 I wanted to use my old 1.2 Mtr Channel Master dish and polar mount with my new TM6900 Combo, So I had to find a suitable actuator to drive my dish but didn’t want a V box plugged in and on show under my new Sony Bravia. I decided to try a Superjack DiSEqC DG100 actuator, which was supposed to be ok driving a 1.2 mtr dish, I had loads of problems with it ignoring commands and not moving properly. I have come up with a solution, by stripping the PCB out of the actuator fitting it in to a box with a power supply to feed the motor instead of the receiver trying to power the dish; this was fitted and powered from my garage near to my dish. So now the PCB’s motor output is only driving 2 relays through an arrangement of diodes, the motor supply is a simple mains transformer and rectifier switched on by the relays so is only energised when a movement command is received, this has allowed me to refit my 18 inch heavy duty Superjack actuator back on the dish and is running faultless because there is no load on the receivers power supply now. Bellow is some photos of the install and a circuit diagram. [/QUOTE]
