How does 79.084 dBu compares to 9 mV/m? What is this dBu term? Please
explain what this means other than it being some line on a map. What
does this measurement mean for my radio reception?


I have no idea what it means for your radio reception.


The equivalent, by the way, comes from the handy conversion calculators the
FCC has on its website. Most of us in radio use mV/m for Am and dBu for FM
to plot contours.... and that is the way the FCC accepts applications.
Jeeze, I even cited a sample FCC filing map showing this.


For the average listener, the precise location of contours is irrelevant.
Either they get a station "well" or they don't. It's been proven with
boatloads of data that AM listeners are seldom found beyond the 10 mV/M
calculated contour of a station and beyond the 64 dBu contour for an FM.
when the signal is weaker than that, it appears that listeners don't find
listening to be pleasurable so they don't use stations with weaker signals.


I wish I could make young people throw away their ipods, their FM
radios, and just about everything else they're interested in so that
they would develop an interest in the amazing hgh and the programming
on your radio stations. However, that's just not realistic. You have
to face facts. You have to make some major changes, and a digital
paintjob ain't gonna do it. You're in a pickle!- Hide quoted text -

To Make AM/MW "HD" {IBOC} Radio 'Work' the
AM/MW Band Needs A New Band Plan :
- - - OTHERWISE DON'T DO IT [.]

# 1 - Designate all FM Radio Licensees as "Local" Radio
Service* Programming with-in an Expanded70 dBu Contour.
* The Key Word being Service to the "Local" Community;
NOT Marketing to the Consumers.

# 2 - Expand the FM Band into one of the soon to be
"Un-Used" VHF TV Channels.

# 3 - Migrate 50% to 67% of the current AM/MW Radio
Stations to the new Expanded FM Radio Band.

# 4 - Re-Define the AM/MW Band to 25 kHz Channel
"Spacing" with IBOC "HD" Radio at 10% ERP.
* Old Band Plan : 1700 - 540 = 1160 / 10 = 116 Channels
* New Band Plan : 1700 - 540 = 1160 / 25 = 46 Channels

# 5 - Transition to All "HD" Digital Radio within 5-Years
with all Analog Transmission ending by the end of 5-Years.

# 6 - Designate all AM/MW Radio Licensees as "Regional"
Radio Service* Programming with an Expanded 50 mv/m Contour.
* The Key Word being Service to the "Regional" Area
{State/States}; NOT Marketing to the Consumers.


that's the plan ~ RHF
