Default AMBrc Problems

Our AMBrc system is having problems with high noise levels, up to over 100 sometimes. We have put it on a UPS and isolation transfomer with out any better results. Has any had this problem and how did they solve it? We race in a metal building with a cement floor.

Would moving the AMBrc further from any electrical equipment work, or what other ideas might you all have.

Thanks for any advice

Only wires near the loop are the coax, which feeds to the AMBrc. Everything is as neat as can be, but not a bad idea, I will look close at the wire routing.

check also...is it running near other power lines? possibly hidden in walls or underground or possibly? could also be an older fluorescent ballast if indoors. Also check coax connections to AMB, if these are faulty in ANY way they could be causing noise. also small cuts in the receiver wire.

Ok, redid the loop and new coax. Thought the problem was solved till it became night time, then the noise level went up to 60 or so. There was no change other then it becoming dark.

Default AMBrc Problems

volav;

Ok, what happens at Night? It gets Dark. So what do you need to be able to see, Lights!

You are getting interference from the Lighting. If your equipment is very close to a Light Pole, try moving it further away. Otherwise a bad Transformer in the light pole can cause interference and even glitching of the cars.

Also, are you using Coaxial Cable, or Shielded Wire?

Normally Shielded wire only has the shield connected at one end. If you ground both ends, it will be ineffective.

You might have power lines that run under the floor. If you have the blueprints form the building, look to see where they ran the power to the building under the slab. Since it only happens at night, is it might be after outside lights kick on. You could also try moving the loop to another location and see if you still have the problem.
