There are so many very cool aspects of this project: I love the phasing receiver arrangement -- it uses the same basic concept that allows my old HT-37 to generate SSB (I struggled to understand it as a kid, and finally succeeded!). The use of the mobile phone as an audio spectrum analyzer is wonderful. The N3ZI signal generator looks a lot like the DDS project I was working on (I should have bought N3ZI's! ). I've been seeing these square pattern PC boards in many projects lately -- I may try this in my next project. And of course, it is very cool to see a circuit designed in Poland being put to use by a fellow radio amateur in Australia -- a good example of the International Brotherhood of Electronic Wizards!
Here is the page for the SP5AHT rig that inspired Peter:
It is in Polish, but Google should translate it, and, in any case, we all speak Schematic!
