RoHS *Shudder* - Well, that is at least with respect to the solder. Bah. Awful stuff. It’s bad enough to flow onto the pins of a TIP120 in mid air, never mind soldering SMD's or through-hole via multiple PCB levels.
I've heard of people build kits (HF Transceivers, btw) with leaded solder and lead-free solder before, the one which used leaded solder got his kit to work first time. The one who used lead-free had at least two bad joints and he's still tracing faults, as far as I’m aware...
Anyway, that’s just my tip for anyone who does build one...

EDIT: Déjà vu, I wonder if this project might follow the same course as the Minimig...
