VK3HN's AM Pulse Width Modulated Homebrew Transmitter

I'm still working on trying to match the excellent results Paul achieved with his AM receiver.  Then this morning I wake up to a Hack-A-Day article describing his even more impressive achievement with his AM transmitter.  

There was one line from the Hack-A-Day article that made me think of Pete Juliano: 

Younger hackers will note the Arduino Nano at the heart of the project, running the VFO and handling all the relevant transmit/receive switching. We can only imagine how welcome modern microcontrollers must have been to old hands at amateur radio, making synthesizing all manner of wild frequencies a cinch.


And once again this story about Paul's AM operations has made me jealous of the obviously great AM homebrew culture that exists in Australia. 

FB Paul!
