Default Analog versus DSP

Make no mistake, the 7030+ is a fine radio, and there are members of
this group who will defend it until death. However it is not for
everyone due to it's lack of knobs and buttons and it's quirky menu
driven system and tiny display. It has a remote that is also very
tiny and cramped and requires you to line it up carefully to operate
as it is optically driven and not wireless driven. I would strongly
advise a hands on demo of it before purchasing or a two week return
policy. See my review of the 7030 at:

People think that digital is some mythical way of making something
better than analog. It's not. It is just another type of solution to an
engineering problem. Generally, the largest benefit is in recording and
playback. Everyone is aware of the benefits in this area, and this,
through the magic of BS marketing been extended to all other types of
problems such as HD and DRM modes of communication. Here the solution is
not any better BECAUSE it does not address the root cause of analog
radio propagation and reception in a way that provides a higher level of
service and reliability. Worse for these digital modes is that the costs
involved are higher for a similar level of service.

Sitting between the obvious improved benefits of audio digital recording
and playback and the utter failure of HD and DRM in radio communications
would be digital filtering in receivers due to the costs involved.
