RFI from Blue Sky MPPT controller. Choke or ?
Hi to the ham radio and other rfi tech types:
My mppt controller is creating a lot of rfi. Very noisy on AM broadcast band and all the HF bands through 10 meters on SSB or CW
The noise increases with current. None at night. I am thinking of wrapping a few turns of the wires from the panels around (through) a toroid cored or the square snap on choke cores I used to see at Radio Shack. Or would a couple of these work as well or better?
I have enough slack and room to work right at the controller input. Can't shield the controller for fear of allowing it to overheat.
Thoughts? suggestions?
Thanks
