That’s
right. It’s a case of massive over protection to the point of ridiculous.
I’m sure you could transmit on 107.7Mhz with 1 watt inside a plane and it
wouldn’t affect the planes communications equipment.
I
notice now that the PDF document on this page is in fact one from 2001.
It’s not a recent release which I thought it was. The LPFM band was
limited to 106.7 to 107.3 at some stage around that time, and then increased to
107.7 in 2002 or something like that. So perhaps we are panicking for no
reason at this stage. It could be that they are only now doing the
technical work that was proposed in this document, and our frequencies could be
safe after all. Who knows.

Great.
That's us out. Ironically last I heard, RSM listen to us in the office.
Does
the GURL for short range devices specifically prohibit broadcasting? (I should
just look it up).
From
my calculations, you could safely broadcast at 16W at our frequency (107.7FM)
without risk (from the graphs) at a distance of 8km from the flight path...
In
Wellington there should be no problem at all because the ILS is operating on
109.9FM. Miles away from the top of the FM band.
In
fact, looking at the table, most places are even better. The only area that is
close is Whenuapai and there peobably isn't much demand for frequency use there
is there?
