FM 89.9 Norfolk Island was unexpectedly heard in
Brisbane during the witching hours and early morning of November 28th,
2009. It has not been heard since.

Unusual weather in the
troposphere enabled this reception to occur. Colloquially, this
phenomenon is referred to as tropo ducting. For more details on tropo
ducting, please visit the learning resources referenced elsewhere on
this site. Luckily for Australians, tropo occurs all year round, but
seems to be more prevalent on days where warmer than average
temperatures exist. It seems no coincidence that unseasonal bushfires
were occurring throughout coastal New South Wales on the day of this
reception. Please be sure to visit my detailed tropo page with analysis of the
synoptic, evaporative and temperature conditions for this day,
including colour charts.

Norfolk Island is situated
off Kempsey, NSW.
Entirely
surrounded by the Pacific Ocean, Norfolk is a renowned tourist
destination for history buffs. It is reputed to have been home to some
of the most terrifying and brutal convict experiences in colonial
Australia.

Norfolk also offers
spectacular scenery, and is best described as an island paradise these
days. To protect the pristine environment, the living population has
been capped, so I don't think you can migrate there, as tempting as it
seems!

This is
the first documented reception of a Norfolk Island broadcast FM station
heard via tropo in Australia. The station was heard on two consecutive
days. It was audible for over 4 hours on both days. For low-powered ham
operators using 144 MHz (the 2 Metre band) in Brisbane, Kempsey and
Sydney, this tropo path to Norfolk Island is quite established over
summer. As no permanent ham operators live on the island, there are no
indicators as to when tropo between Australia & Norfolk Island
exists.

At night time, FM
89.9 Norfolk
Island relays the Remote Western Australian Spirit
Network
uninterrupted (that is, including ads). Hearing Western Australian ads
can be a little confusing for those unaware listeners! Daytime
programming is predominantly locally hosted. News is sourced from the
Australian Broadcasting Corporation, Radio New Zealand and other
sources. The station also simulcasts on AM. The old callsign is VL2NI.
