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

[Ken N9VV]

I for one would vote *YES* for a single board type of Rx/Tx if it 
were possibly cost effective.

Many of the kits that are made by http://www.qrpkits.com are 
single board designs with some thru hole parts. The SMT parts are 
commercially installed. This has the dual benefit of (a) making 
sure the kit can actually be constructed by a klutzy Ham like me; 
and (b) attracting a much broader range of builders who can put it 
into a box with a few connectors and controls. The larger audience 
means economies of scale for TAPR (or whomever designs this kind 
of a rig).

The AOJPxyz kits are just way beyond the capabilities of many of 
us plain-vanilla hams. I am afraid many of us are afraid that the 
TAPR boards might be exotic engineering trophies rather than 
practical workable ham rigs. A new design might go a long way to 
strengthen the SDR future.
