[Lowfer] 472-479 kHz

[Douglas D. Williams]

So what do you gentlemen think about the WRC-12 MF amateur radio
allocation? If I understand correctly, it seems that any nation not wishing
the allocation can simply "opt out". Do you think the FCC will?

7 kHz isn't very much spectrum, so I imagine all that will be allowed is CW
and narrowband digital modes.

1 watt EIRP doesn't sound like much, but it is still far more power than
allowed in the part 15 "Lowfer" band (1 watt INPUT). Even though the
frequency is higher, most amateurs are still only going to
manage very physically short (for the wavelength) antenna.

Speaking of the EIRP limit, I wonder how most amateurs will adhere to that
rule? Knowing how much power you are putting INTO the antenna is a simple
matter of a wattmeter. Knowing just how efficient your antenna is at
radiating that power seems a bit more complicated.

How do the European nations handle the 136 kHz allocation they have? Do
they have an EIRP limit or a simple Input power limit?
