After asking for some help finding the 6th Edition of the Radio Communication Handbook on GQRP list I also exchanged a few emails with a few others others and Mike G3TSO the designer of one of the has sent me a lot of information. So will look at building a variation on this design.
In addition I have started to look at the older Kitten II that was covered in SPRAT (from G3ROO) as well.
I also have the board layouts and many of the components for the Multipig+ rig as well.
The modular nature of all these constructions are of interest.
