[HCDX] RF water meters
City of Enid has started replacing all water meters with newfangled ones which do not require a person to walk around and read each one individually each month --- instead they radio-in their readings on a frequent basis, with all kinds of useful info, like detecting leaks so customers can take action immediately.
But they also will have an antenna sticking out of the ground --- watch out, mowers! And there may be criminal penalties for tampering with them.
WTFK? Nobody bothers to tell us that. But I can see the noise floor going up noticeably all over the city, not just around traffic lights. Let alone the potential for direct interference on intentional or unintentional frequencies. I suspect this system is more than just transponders, but individual transmitters on every lot. OTOH, if they are not transponders, they would have to occupy a huge number of discrete frequencies to avoid interfering with each other.
Does anyone have experience, positive or negative, with these things elsewhere? (Glenn Hauser, Enid OK, DX LISTENING DIGEST)
