First, thanks for Soldersmoke and all you do for us QRP hackers around the world. I'm a big fan!
I've detected you are getting sucked into the world of microcontrollers of late. I know you are not really that excited about SDR but this is a radio that combines Arduino, the currently popular SI5351 and a Softrock to make a very functional SDR. I started this project last year which uses the fabulous Teensy 3.1 and companion audio shield. I recently packaged it all up and it looks like a QRP radio now. Still doesn't transmit but as I like to say thats "just a small matter of software".
There are several posts about it on my blog. The most recent:
There's a link to a video and a link to the code in that post.
Rock on Bill!

Wow Rich that is really beautiful.  Amazing!   I am also sending this to Pete Juliano, but I was at first hesitant about this because I feared that your combination of Si5351 and TFT display might be TOO exciting for him. Deep breaths Pete...  
73 and Thanks,  Bill

Hi Rich & Bill,
Wow –really exciting project Rich! Congratulations and Bravo!
This is so exciting, for all hams, as this just shows the power of the available low cost technology that is now on the market. Your project is really tempting as I have a V6.2 15M softrock sitting in a box (somewhere). I was somewhat put off with the Power SDR as the opposite sideband rejection is not too good –it is clear you have cracked that nut.
Thanks for sharing Rich and yes Bill I am taking very deep breaths.
