This forum always talks about events and real-time wind weather e.t.c. ...
Community radio station for coastal recreation districts dealing more with specifics e.g. "real-time transferred online reports of ocean and weather with GPS by user to the station website for update"
tis to "pilots and
NOTAM's" e.g. when an occluded front stall and lee waves occur in low level flying or a front with a newly formed Cumulonimbus.
Simply much more casual and user friendlywww.airservicesaustralia.com/wp-content/uploads/NOTAM-Group-Management-User-Guide1.pdfI've been at an old problem i get not good enough radio reception, but then Short-Wave never is until use of a long lateral antenna and most outback or remote locations only send -resend "radio national" (ABC radio for those that don't know) weather AM or FM (never mind DAB for now).
Good antennas are a problem to find or use but too then also are how they work and
what you are getting from the transmitters capability (distance for wattage).
Long ago with some metallurgy and minimal know how from a few simpler wave-mechanics articles
i reasonably solved the reception problem albeit somewhat "a bigger hammer".
HOWEVER, the real world of listening is an interesting one, there are many FM stereo broadcast community stations i find only use
100w transmission that is lost over 5km or at least its quality severely degraded.These FM stereo public broadcast stations for local news, events, environment and condition
are powered by sets that can often be bought for close on 1k aud each, and are much a packaged unit or set off the shelf (notwithstanding government licensing and other technical requirements such as the transmitter tower mast location
governed by the 1971 act of Australian height Audit)

(So saying brings me to an interesting little point, the 1w and 5w FM stereo public broadcast sets that can be bought on ebay at quite a cheap price or in bulk sets of them, these i can only presume are to keep megalomaniacs in line by notifying police by computer automatically at point of sale on the net).30 years ago as a teenager i was a presenter(on air announcer) at a community radio station and learned the
general good minimum for area broadcast outside of cities required 500w not a mere local district 100w.
More than this,
a technology called circular polarisation of the transmitter antenna was used to give better reception in cars and during bad weather as its audience in the remote outback would likely hear it it during transit more than in a home.
circular polarized: cdn.thomasnet.com/ccp/10014548/223252.pdfThe final piece of information,
circular polarized antennas have field area characteristics that are dependent on the design of the antenna elements shape shedding of the waves making it possible to choose a "North South affected" oval or elliptical field broadcast design of the area cast with the circular polarised antenna (manufacturer documentation dependent).

a short-wide chunk of area over a populous at one end such as ei.g. Hornsby with a longer thinner coastal strip half ocean and half land by point of antenna characteristics setup.
The point, radio stations serve their best as regular update of real time information that the user does not need to manipulate to gain access to the information (in a boat or on a paddle board yacht e.t.c.) because hearing (the easiest to co manage during a tasks threading, they do not need to stop their tasks and activities to access information) is easier than affecting what they actually see or need to manipulate, along with more "living social point" aside to computing, flags or flashing lights (those too often require pre known registered periodic intervals to manage activity cohesion).
