what can cause a ka false?

[jdreynss]

Hey guys, I know that everything under the sun can cause k and x band false, but what could cause a ka band false?

Cobra radar detectors.

RMR "detectors".

I have read somewhere that credit card machines being used in places like convienient stores use satalite communications. They use frequencies in the Ka Band, but I don't remeber the specific frequency. If my memory serves me correct, I think they are also using frequencies in the Ku Band as well, although not an issue for us.

Also, I read this a long time ago. Might have been talking about companies applying for the use of satalite communications for credit card machines. If anyone can expand, please do.

A very strong K band can put out an image that will make your RD think it has found Ka band.

Even high-end detectors can mistake K for Ka when it is strong enough. ==

My neighbor's Direct Tv dish, which sits on the ground, gives me a Ka alert; but it is a very weak signal.

I've pointed a bushnell at my STi within a couple of inches and the STi went off on Ka.
