[NLRS] RF read water meters

[plefever at cpinternet.com]

Jim,

I live in Burnsville and they came through a few years ago
and retrofitted all the meters in the city with RF read
modules.

I was home the day the tech came to install the module. They
sure love it when you move the water softener and clean and
vacuum the area around the meter and provide a work light
for them! I had the same question for the tech and I asked
him what frequency the meter was on. He stated that I was
the 2nd person to ask that and he asked if I were a ham too.
At first he was hesitant to tell me but he saw the bench
with the scope and spectrum analyzer on it and he said he
thought I could probably figure it so he just told me the
exact number. I don't recall the frequency but like Gary's
it was in the 900 Mhz range.

I don't think the module on the meter talks unless its
polled so I don't think you will hear anything from it. I
don't have anything on 900 Mhz personally so I have no
actual experience though.
