Very cool. I like his description of how he found parts for this transmitter:
The power amplifier tubes needed ventilation as well as shielding; that was always a challenge because I had no good source of perforated metal. The black sheet with the round holes actually came from the cover of a car air filter that I found in the trash.
There is a lot more interesting stuff on Nathan Zelde 4Z4GE's site:
