[hpsdr] single board rigs *YES* please...

[Bill Tracey]

Specifically,what about the current AJO boards is beyond the 
capabilities of the canonical ham today?    Should the canonical ham 
be the target for an HPSDR like project - or are we more looking for 
the bleeding edge ham?  Should we be trying to drag today's canonical 
ham into the future?

One of the reasons for going with the Atlas setup  was to be able to 
have basic building blacks we can mix and match -- and in fact 
we're  getting there -- we have a controller/ PC connection board 
(Ozy) and an audio A/D  and D/A board (Janus) for use with existing 
front ends ala Soft Rock  and SDR 1000.  Penny and Mercury will give 
us wideband direct sampling xmitter and receivers -- should be 
exciting.   At the same time I've got some basic blocks to experiment with.

The board we're missing is a DDS + xSD/xSE + filters to go into Atlas 
and feed Janus.  That too is a disappointment for me.    I did ask 
the audience in my talk at the DCC this weekend what they needed to 
experiment more with Ozy and Janus -- most of the responses were on 
the order of "We need  OZY for Dummies".  If there are folks 
interested in working on doing such a course  step on up - I'll be 
willing to help.

The thing I do not like on a single board setup is that it is very 
hard to experiment with a single board.  With the building lock 
approach one can experiment with different technologies without 
having to redo the entire radio from scratch.  Too me, this 
experimenter friendliness is a prime goal of the HPSDR 
project.  Guess the question is are we building one radio, or a set 
of components that can be put together to make a radio.

Cheers,
