There are a couple of frequiencies for unlicensed low power am stations. You
can see them in use by real estate folks selling houses. There are no
commercial stations on the frequency.

In that case, simply modify the sign to "Tune to 560, it could save your
life" and use a discrete frequency low power transmitter.

I assume you mean to take up an unused local channel? Or to bargain for
time on a used one?

Both ideas make sense.

Yes, and at Disney World, etc. This is a very doable idea and may well
solve FCC/DoD issues.

When was the last time you listened to one of those frequencies? It won't
get the message out where it's needed.

I can't find the part of the FCC regs that provide these frequencies for
unlicensed stations. Can anybody share the chapter and verse?

It can be found under the section that allows a transmitter as long as it is
less than some number of milliwatts per meter.

If you really need the exact section, I will drag out the regs and get it
for you.

That is part 15 and it isn't just a couple of frequencies, it is any
frequency in the AM broadcast band (and the FM broadcast band, for that
matter).

Specifically, 15.219 allows operation on any frequency in the band so long
as (a) the input power to the final stage is less than 100 mW and (b) the
antenna "system" (radiating element, coax, and ground lead) is less than 3
meters long.

15.221 also allows operation with an unspecified power level into leaky coax
with a field strength limitation.

Power is not milliwatts per meter. Power is milliwatts. Field strength
(also an allowed measurement) is in volts per meter.

The OP said that there were a "couple of frequiencies(sic)for unlicensed low
power am(sic) stations." That implied that there were a couple of
frequencies that were unused in the AM band by commercial stations, and I
just wanted to have a reference to WHAT they were and WHERE in the regs they
were delineated.

In this case the milliwatts per meter refers to frequencies stated in
meters.

Volts per meter only applies to the E component, the magnetic component is
always stated in amps per meter.

I will get back to you on the specifics. I am pretty sure that my brain is
not suffering from a senior moment as to my recollection of the regs.

Truth is, I was thinking about reserved but not yet assigned AM/FM
frequencies.

Does this fall under LPFM/LPAM?
