But there's a couple of problems:
1) I'm starting to really build up a back log of radio projects now; and
2) I really should try and only focus on technical topics for my exams (which microcontrollers are not even slightly mentioned) as there's still a few items I need to re-visit to really embed.
Oh well, hopefully eventually I can play with these. Maybe once I start building some basic radios I can incorporate these. Maybe for a morse keyer, or a digital read out, or some kind of cool computer interface for either SDR or digital modes, we'll see.
