If it has been there for a long time either something changed in the

The guy did ok on the first part explaining how power factor works but fell
down when it comes to the "save money" part.
The utilities do not charge you extra or give you a break if you do or don't
have any power factor correction. Unless you are an industrial customer.

The meter reads P-P just like the scope. I generally set dev with the meter and

they don't.

You might be able to get the paging company to swap out the transmitter

Very nice explanation of the issue.

There is something wrong with your SM, then, as it should not show a
deviation of 15 kHz on a signal that is 15 kHz P-P unless it's only
deviating in one direction from the carrier.
The +/- 4 kHz sounds about right. But, it should be centered around the
carrier frequency of 157.740 (Or, on 157.
I have noticed the carrier appears to jump between +4 and -4 Khz of center.
The transmitter is about 75 yards from me. It's running 225 watts according to
the tech.
The interference is pretty strong. It competes with my base station on low
power. I'm 25 miles from the repeater.

Before you said 15 kHz P-P (IOW bandwidth). Now you're saying 15 kHz
deviation. 15 kHz deviation would be way too high.

The utility I used to work for did a lot of testing on the "get free
electricity" devices over the years. None worked unless the customer had PF
issues, even then, it didn't do much. That simple spinning disk electric meter
is surprisingly accurate and hard to fool.

Tim,
Digital paging (mostly POCSAG coding these days) is FSK and will
easily occupy 15KHz of bandwidth.
On a Service Monitor deviation screen you will see a square wave
pattern that looks like it is overdeviated unless you are very close
to the transmitter in question. Read on and you will

The deviation is 15 kHz, or you're seeing 15 kHz of bandwidth on the

Might also be worth putting the Spectrum Analyzer on your input to see
