I didn't ask you about your fake imagined history that you shoe horn in
at every opportunity.

Call Bob DuTriel, the associate of Ron Rackley (the formost authority on
directional AM antennas in the US) in Florida and ask about me. I assisted
Bob while he rebuilt the WQII directional when I decided to reengineer the
station.

The minimum contour for FM stations to get significant listening is
the 64 dbu, roughly 1.5 mv/m. For AM in metros, it is about 10 mv/m.
Both AM and FM are measurements of the strength of the EMF from a
transmitter at some point of distance from it dBu used to be called
dBv but got confused with dBV, and was changed. It's a decibel
measurement of voltage.... as my equivalency shows.

dBuV is not the same thing as dBV. Care to try again.

I said that, historically, the tem was changed from dBv to dBu because folks
were confusing dBv and dBV... that was the origin of the "u" in dBu... which
bagan with a lower case "v."

While you are at it explain how 1.5 mV/m equates to either 64dBuV or
64dBV.

Equivalent field strength expressed in with a different scale. Even my
speedometer has two different scales, and they have equivalents all the way
along, just as a metric tape and a yardstick do.

My radio needs 10V/m to receive a station decently? My God no wonder you
didn't believe my posts on the signal strength of local stations. I'm
glad we finally figured that out.

I don't care what your $5 thousand dollar radio needs.

The fact is that after examining thousands and thousands of diary mentions
for at home and at work by ZIP code, it has been found in several different
studies that 80% of all FM listening takes place in the 70 dBu contour and
15% to 17% more takes place between the 70 and the 64 dBu contours. There is
nearly no listening outside the 64 dBu contour. So, most of us actually
running radio stations or involved in programming know that there is pretty
much no potential for listener growth outside the 64 dBu contour as it is
apparent from empirical evidence across a variety of markets and ratings
periods that listeners do not listen to relatively weak signals.

The same studies, on AM, showed that in and in the environs of the Top 100
metros, there is pretty much no listening outside the 10 mv/m contour. This
corresponds with more anecdotal evidence that shows that below 10 mv/m the
signals are so subject to man-made interference from everything from
computers to traffic light controllers that they are annoying to listen to.
In some metros the minimum level seems to match neatly the 15 mv/m contour
or points in between, probably indicating greater noise levels in the market
in general.

Again, it is not about whether a station can be received. It is about
whether listeners, in any significant quantity, are able to enjoyably listen
to a station. And it has been proven that a pretty intense signal is
necessary for a station to get audience in the rated metro areas (where
about 75% of the US population lives)

And, as I said before, the data, the methodology and the tabulations are
audited each year by a team of researchers named by the Media Research
Council, formed by the advertisers and agencies that use media research such
as Nielsen and Arbitron.

That sounds like the one I bought. It goes with me everywhere. And I
rarely have a signal outage....except for under bridges in rural areas.

Everywhere I go, I can listen to what I enjoy via satellite.



Glendale, CA, in hilly area... no signal at all.. La Quinta, CA to Palm
Desert (my bicycle route) spotty signal, dropouts at least twice in any 5
minute time in motion. Prescott, AZ, no signal at all in area I live. Waste
of $300-.

I had a DJ friend at an AOR station in Nashville back in the 70s when it
tried Dolby tell me that only the deep fringe listeners could benefit
from that and besides not being in the SMSA most of those hicks didn't
have the gear for it.


What is an SMSA? Arbitron only has TSA and MSA.

This evening, I locked on KNX in HD around Rialto on the 210 fwy, and
carried it to near Dodger Stadium without a dropout. Rialto has something
like a 3 mv/m signal for kNX whose 5 mv/m ends just a tad to the east of
Pomona and before Ontario.

Actually, I have the real ratings data and you do not.

Snip

What you have is your overactive imagination not facts.

I am going to keep you busy finding out how wrong you are. Call Owen
Charlebois, at Arbitron, and ask who I am. Owen is President, Operations and
Technology, for Arbitron. He was formerly head of the BBM in Canada.

That would only be a couple of blocks around the 50K station antenna
with Eduardo's 10V/meter contour. Whatever that means.

You don't know what a 10 mv/m contour is?

Really. I"m not familiar with Ca reception, but I have a colleague in
Prescott who listens to the same XM channels I do, on the same radio, a
first generation MyFi.

You guys throw a lot of listnership away if you're requiring 1.5mV/m.. since
even cheap POS radios have FM sensitivity down in the low hundreds of
microvolts, and good ones (home and car stereos) are good down to 5-15
microvolts.. you're almost a full order of magnitude higher than the average
car stereo... (order of magnitude = 1x10E3)

I had an XM Eno (it went the way of the dumpster) and in the Hassayampa area
of Prescott, there is no signal anywhere. I am pretty convinced at this
point that the portables need to be near terrestrial repeaters and can't
really see the satellites.
