RFX75 Fan!

[longhaireddwb]

I have installed one of these RFX75 units and my radio is swinging big time. Now I picked up a small computer fan. 1 1/2 - 2 inches dia. I have it installed on the top of the RFX75 unit but when I try to wire it into the radio I'm picking up noise ether in the RX or the TX from the fan.

Where can I hook this up so it don't cause noise?

Where are the power wires coming from to feed the fan?

If it's not a brushless fan you might consider one.

 

[Robb]

Yeah; brushless would probably be better.

brushless fans? I'll check into that. As far as where I'm hooked up. I've tried about every spot on the board and the power switch and the power connecter and I always get noise somewhere. I'm about to just go without the damn fan!

Wait a minute! I'll move the ground! Maybe that will help!

All connections on the board are above ground and should be avoided.
