I think we've already established that he doesn't care how the radio is
made, and how the RF is generated.. What is going out over the air is the
issue.   

I think putting proprietary protocols, codecs, or modulation schemes on the
air is against the spirit of Amateur Radio and should not be allowed.  If
you want the software or hardware to be closed source, fine, but the
transports should not be.. save that for the internet and consumer devices.

Much like the other VoIP offerings we've embraced as transports for Amateur
voice over the internet, it looks like the on-air transports are heading the
same way.  I guess no one has ever heard of SIP/RTP, IAX2, Asterisk, SER,
etc.  There are plenty of open protocols and codecs that can be used,
adapted, improved, or hey, can be CREATED for use in Amateur communications.

I think it's almost hysterical that Kenwood comes out with a few radios that
essentially lock-in the APRS protocol until a successor arrives and there's
a huge outcry, and then Icom comes with the proprietary lawyer-protected
D-STAR system and it's the best thing since slice bread.  Don't talk bad
about the D-STAR.

Times change.

35 years ago the majority of clothes in the United States were hand sewn at 
home.    People used to stuff their own sausages.   I grew up in a town on 
I-75 (of all places) that had no fast food restaurants - not even on the 
freeway exits.   Full service gas stations were on every corner.   Pizza 
used to taste good, now it's a piece of cardboard and slime you buy at 
Costco.   I remember going to the Heathkit store...and people used to 
repair toasters.

What's your point?

Imagine trying to build an HT with similar packaging and feature sets as
what you can buy today.  It's about as practical as asking your
wife/daughter/girlfriend to sew you a new shirt.
