So here we are, more natural disasters & AM Radio saves the day again.
I even heard while listening to the ABC yesterday afternoon, them saying (paraphrasing), there are difficulties with some transmitters in the South Coast areas, due to transmitters mostly being located on top of hills in difficult to access bushland areas & power loses & bushfires are affecting them.
Funny thing is they kept mentioning that the mobile networks & internet were also down or having difficulties, but then would say if you can’t get us on the radio, you can always listen on the ABC app for emergency information.
LOL, like that’s a reliable or even available option if you’re in or near the danger zone, & I’m guessing most people would want to save their phone battery for if they need to make an emergency phone call, seeing as the power’s out & they can’t recharge it.
Almost every natural disaster we have the same issues with FM & TV.
AM is always the backup & usually gets called into use.
AM TX sites are almost always accessible during a bushfire, & in little danger of burning down, due to only a grass fire racing across the TX site. Even in a flood the AM site can be accessed using a boat, & if it’s in a known flood area the TX building & antenna (mast) base is built up high above the flood line, so the likely hood of it being damaged is low.
As most of you know I work in Broadcast TV & Radio, & we have self imposed restrictions on accessing our TX site during bushfires, storms, etc. even if they’re not enforced by emergency services.
As you probably saw in another post elsewhere in the forum, we had no access to our Kurrajong Heights (Sydney West) site for well over a week due to road closures & bushfire risk, had we have lost the site altogether, it may have been days or more than a week before we could regain access to even start looking at the rebuild.
Don’t think it’s just regional areas in danger either, Mt Dandenong wasn’t maned on Monday due to the bushfire risk, & had a bushfire occurred at Mt Dandenong & damaged the site or caused a major fault, the entire Melbourne area could be without TV & FM radio for as long as it takes to again get access to the site to make repairs. Adelaide, Perth & even Brisbane are in the same situation.
Everyone’s wanting to turn off their AM’s & convert to FM, but what are they going to do (as a business if nothing else), when a bushfire burns down their FM TX site & they can’t broadcast anything for perhaps weeks, until they can even get a low power temp setup operational?
The ABC at minimum should be forced to provide full overlapping (by minimum 2 TX sites) coverage of the countryside (within reason) & as per historical coverage, with AM transmitters of 10, 20 or 50kW power out, for specifically the reason of emergency broadcasting coverage to get information out to the masses, & as a result, all radios sold in Australia should have AM reception capabilities, unless or until DRM using the MW band & MW TX sites is implemented moving radio into the digital world.
