Pics available of the big girl yet?

Any Ambos on the forum? My Radar / Laser detector often goes off when an oncoming Ambo approaches. Coincidence?
Also, Metro and Regional Ambulances have ESA and ESB channels or just Metro?

g'day guys,

Hate to be that guy but im in the 6056 (Midland Area) and im wondering what the best frequencies are for the St John Ambos?

None

they have been digital encrypted for a while now.

Damnnn it, scanning is seeming more and more pointless, in no time DFES and AIR Band will all be digital, ugh

DFES, yeah sure that could happen same as any emergency service they are one of the last to go that way. Air band good luck with that, digital over distance is not exactly a great idea.

any reason? interference? soo im curiosu this is all new to me haha

For air band? Just my thoughts really imagine tens of thousand of aircraft that can't just swap a radio, then the tens of thousands of ground stations, navigation beacons etc.

The low frequency AM transmissions are best for long range usability, not about interference. One main drawback of digital is if the signal is only partially complete, the whole message can be unreadable. With analogue you can have a poor quality transmission and still understand it.

sorry in lame mans terms the same as a digital and analogue tv? so even if ts distorted you can still work out that its big bird of of seasme street where digital is more on and off?

Yes that's a great comparison.
