The DRM standard in part uses proprietary code licensed by several

I don't know what you are talking about here. This software is being
sold and is not free. If there is a free DRM radio decoder I did not
know about it. I don't understand how this could be because some of the
encoding/decoding algorithms are not free. Please point to the free DRM
decoding software.

You are missing about every point in the thread. The DRM Troll started
out saying that the DRM SW was imminent because consumer radios existed.
There is one that I can find no thanks to the Troll. I don't know if
this one radio is actually being sold since it is described as a
"concept radio." He kept posting links of the same radios that are not
SW radios but are AMBCB or FM. The radios that did receive SW need a
computer to operate or they were very expensive professional rack mount
units. Basically the radios that need a computer are science experiments
for early adopters. There is no analog equivalent DRM SW radio being
manufactured today as far as I can tell.

Of course there could be a DRM SW equivalent tomorrow. Of course any
company with the resources could spend the money to produce ASIC's to do
the job. It is just that they haven't done it yet contrary to what the
DRM Troll is espousing.

A DRM radio needs to perform many functions compared to what an MP3
player needs to do. Additional functions over what an analog radio
requires so even if a well financed company decided to build a high
order of integration with several ASIC's a DRM radio would still draw
much more power than a analog radio. Standard batteries many not be able
to handle the power requirements and when DRM SW portables show up they
will probably use lithium ion rechargeable batteries.

There is nothing magical about DRM technology. Everything used by the
DRM scheme is used someplace else. Nothing new here and that might be
part of the problem of a technology not well matched to the SW
propagation environment.
