A new hobby is probably the last thing i need to get into right now, with all the PhD work I've been procrastinating on.
That's never stopped me before though.
I've had a passing interest in amateur radio for a while now and ever since I pushed it as a Barcamp topic a few years ago, I've had a few people "encouraging" me to get my license.
So now I'm finally going to do it and enter the world of amateur radio. This should be interesting and fun.
