It appears the market of mobile SDR radios is beginning to be tapped:
Elecraft's new KX3: http://www.elecraft.com/KX3/kx3.htm
This is an SDR HF/6m radio at heart, and the closest any commercial
product has come to a fullblown SDR HT for HF/6m (will have a 2m option
as well.)
It's an SDR HT with an traditional-style front face. This is what the
Elecraft's customers appear to have wanted, with a standard VFO, etc.
Has computer hookup capabilities, etc.
The firmware however is probably going to be closed source as I believe the
rest of their firmware is.However, an open-source SDR mobile radio that's
*easily* accessible to any ham would be of enormous benefit.
-------------
on the open source side, I'm sure there is some incredible talent over in
GNUradio that might be able to help out or pull from.

Awesome Bruce!
*cheers*
have you looked at some of the second-tier, "new-line" Amateur companies? I
would not be surprised at all if the corporate culture found in some of the
companies would welcome something like this. There are a lot of small Amateur
companies that have existing Commercial & Amateur lines, manufacturing and part
sources laid out already.
The key would be packaging the idea in a mutually beneficial way, without
compromising quality and consistency of the dream.
Alinco, TenTec, Elecraft and others like them might be fertile grounds for this
project and Venture money too. Leveraging existing supply chains and
manufacturing infrastructure would smooth the road to adoption significantly,
with a name-brand to boot. Even someone like Tokyo Hipower, who doesn't
necessarily have transceiver experience but does have the
technical and supply chain expertise may be approachable.
The key would be how it's presented and to whom. What do you think?

I have started to shop around to my venture capitalist friends a business plan
to produce open platform SDR HTs and mobiles. I'm not particularly interested
in waiting for the old-line Amateur companies to get involved.
The plan is to produce a mobile first, because we know we can fit everything in
the form factor today. The radio design presently looks a lot like USRP with a
multi-band receiver front-end
and transmitter, a speaker amplifier and microphone preamp, a Linux system as
the built-in "host" and application platform, and a touch-screen as the user
interface.
There will be two versions of the system and its software.
The commercial version will be FCC certified for its bands, will be
closed-source, and will use cryptographic locks to assure the integrity of the
software.
The amateur version will be open platform, and will be hard-coded to lock out
some receiver frequencies in order to comply with the US FCC requirements for
commercially-produced Amateur equipment (which come from ECPA 1986).
The system will be capable of operating spread-spectrum or narrow-band. There
will be no hard-coded modulations, packet formats, codecs, etc.
It's my opinion that this is the only serious radio architecture for the near
future. We're at the point that it's becoming less expensive to produce SDR
than conventional radio.
Smartphones show where we should be as far as user interface and applications.
Thanks
Bruce
