The argument that HD is better than analog is BS.

HD or IBOC is the system first to be dropped.
DRM has the same options and could work for ALL bands, AM (= MW) AND
LW, and SW.
IBOC for AMBCB takes far to much spectrum, and is useless, both in and
out the USA.
DRM can also do simulcasting, but now also takes to much bandwith.

Digital Radio is a nightmare by itself, having more than one system is
outragious.

But Digital Radio or DRM. wether simulcasting or digital only, will
never fly and does noy solve any problem.
Apart from technical disadvantages: ALL bands suffer from instabality
- night- day, summer winter ansd are vulnerable for noise blocking
digital reception at a certain level. The answer to that will be more
POWER and now also the digital signals will block their co-channel
outlets. And this will bring us back in the stone-age of AM, to many
stations, with to much power. CReating a real mess after dark.

An even better solution would be to increase AM bandwith by re-
allocate the entire band and use 20 kHz grid. in Europe 18 kHz. This
will leave the strong stations in better audio-quality and is
competable for existing receivers, even they wil have the advantage of
better audio, however not fully. New receivers will be adapted to the
new system. But you dont NEED to by a new receiver, and the wider
audio spectrum doest not cuase the level of interference (hiss) as
digital radio.

Digital radio should be on VHF/UHF, and there must be one system.
T-DAB is obsolute, here in Europe DAB + seems to be the future.

But this will take a very long time, so the idea is to use all
analogue capacity for a very long transition period.

BTW, WW2 is back in Europe, believe it or not.
During WW2 the Germans misused radio heavily for Nazi propaganda.
After the war in the Copenhague conference Germany was sanctioned for
this and got very limited AM channels. The answer from Germany was
FM!!
So Germany became worlds first FM country, the AM's were on and did
nothing but copying the FM-signals. Later many AM's were dropped. The
Germans did not know what to do with it, untill recently, and many
dark AM's has been fitred up again with ......DRM.
Causing terrible noise to other stations, co and adjacent channel.
The Krauts dont care, they dont use analogue AM, but neigbouring
countries AM reception is suffering. So WW2 lives on........
