This may be way out there. Has anyone looked that the electronics inside of one of these positioners and come up with a way to run the motor with an external power supply?

I was wondering because of lessons learned how power inserters can help power hungry lnbf's and increase the life of receivers/wall wart supplies.

I'm doing tons of reading of setting up ku along side of c band on my 12 footer.
Seems there are many pros and cons. So a dedicated steerable ku dish setup looks better.
The more I thought about it, if there was a way to more closely resemble moving the dish like a c band diseqc controller does it would let me get the required motor voltage/current at the stab and let diseqc do the move commands.

My idea was if you could supply ready motor power and when a diseqc command from the receiver was received to move the dish, use the power instead of what comes over coax from however many feet away.
A schematic of one would tell me in a few minutes.

It would be a cool way to repurpose one of the old solar fence chargers I have lying around here.

Just asking is all. Thanks!

You may find info on what you are looking for here. :)

Naughty Mods I: DG-380 Separate Drive Power

wiring the impossible (Post 3)
 
From my recollection a STAB usually doesn't take more than about 300mA. So I don't know how much current your receiver can supply, and if there really is a problem?

Otherwise: see STAB 90 Dish Motor Needs More Power!
and the links in there. (The above links by FTA4PA are also there. ;) )

Schematics of one type of board of the HH100/HH120 motors is in this topic:
STAB HH100 onderdeeltje doorgebrand
BTW The italian link in the first post does what you want, IIRC. (The STABs have solid state relais...) :)

I've noticed recently though, that there is another (smaller) board for the HH100 and HH120. Don't have any specs/schematics on that.

So, nice time to test your language skills (dutch, italian) again? ;)

If you have adequate signal from the LNBF and can spare a few dBs, install a splitter between the STB and the motor. Run one leg to the LNBF and the other leg through a 18Vdc power inserter then to the STAB 120. The motor will always see 18Vdc and provide maximum speed no matter if the STB is on a vertical or horizontal tp.

Please note, some inserters don't pass 22KHz/DiSEqC.
