AJAK and ASC1 noise

[hank123]

I keep running a few tics off from time to time and after speaking with Brian I know its because of the noise from the motor.
Where do I need to install the 50v capacitor?
Brian also talked about moving the board around but I have no idea where else I could put it.

Thanks

Mine looks like this. I have my own reed switch plate but not really different than the original. I put a terminal block on the switch plate to get the switch wires away from the motor as much as possible.

If you have a cap with long enough leads you can just stick one lead under each motor wire terminal screw in the terminal block.
Yea just like that

I was referring to how the reed switch sensor terminals are located closest to the motor and the motor terminals are furtherest away. Some folks swap the wiring of the two motor wire terminals with the two sensor terminals and route the sensor leads away from the motor.

The capacitor leads can be mounted between the two motor terminals.

Edit: yes, just like that!

Wow Magic Static that is clean!
My gear wiring looks different then yours Magic.

KE4EST between the white and red wire?

Correct, stick something like a .01?F capacitor with at least 50V rating, between the White and Red larger wires on the left of your pic.

Cool deal thank you. I should be able to get this done this weekend I'll update when it's done

That's the reed switch. I have made an improved sensor for my AJAK
In this thread I discover how to do that. http://www.satelliteguys.us/xen/threads/10-cm-perf-on-ajak-h180.311276/

What would be better to use?
And yes Radio Hack still carries some stuff.

 

[KE4EST]

I would use the Ceramic discs, but either should be ok.

 

[hank123]

This work ok?

 

[KE4EST]

Yes

While you have the motor open, swap the M1/M2 terminal wire with the S1/S2 terminal wires. You might not even need the capacitor if the sensor wires aren't running against and the terminals not next to the motor housing.

Also, connect the S1/S2 distribution wire shield drain inside at the controller to the GND terminal and disconnect the shield drain wire from the HH motor housing terminal. Connect a wire from the HH ground wire terminal to the dish ground and bond to the structure ground to prevent voltage potential. It is better to ground the distribution bundle's shield drain wire(s) only on one side. The structure side ground connection will usually provide better results.

I have been meaning to ground it. I'll get me a grounding rod this week and drive it in next to the pole.
I do think your right by doing this it may fix most of the problem.

Thanks guys for your hellp.

Remember to bond to the structure ground. Without a bonding wire, driving a second ground can create more problems than solving.

3-4 foot galvanized rod a foot away from the pole, copper wire, galvanized clamp, I would hope would work fine.

To connect from the dish ground rod to the house ground rod?
