Re: [HCDX] [dxld] AIR to turn digital for world audience

[Glenn Hauser <wghauser@xxxxxxxxx>]

Boy, have they been snowed by the DRMists. AIR can`t even put a reliable analog
signal out to 20 megameters, e.g. North America, and doesn`t even try as far as
official target areas where the Western Hemisphere is not on their map. So how
are they going to make it ``crystal-clear`` with DRM? Not without relay
stations, they won`t, and they have never in history even attempted to use SW
relays abroad, unlike countless other international broadcasters who in effect
now have a worldwide network at their disposal and may use close one-hop
transmitter sites from the targets if they wish to. Furthermore, altho there is
a hybrid DRM/analog mode available for SW use, no one is using it. It`s one or
the other, and there must be a reason for that (Glenn Hauser, OK, DX LISTENING
