My favorite topic in college, my focus in my MSc... What about it. Saddens me sometimes thatI never really turned into a career..

At least I dabble with it in my freetime  

 I've been jumping back into HAN radio. Seems there's opportunity for open source to improve the radio arts.  

 I don't know much about it, I know how it theoretically works. I have a SDR lying around that could be used as lab rat.. 

What's on your mind?  

 Open source radio dev. Specifically the VARA modem or some version of it.
