Welcome to the PA3CSG website!
Big RF amplifiers with cheap Russian valves, and serious filters for them.

Notable for the bit on slot antennas. (The three-band J-pole-with-slots combo is pretty neat, although I'm not entirely sure I'd want it on the roof!)
Extremely impressive homebrew radio gear. I particularly like his recased and modified MKARS80, and the linear amp he built to go with it.

Hm, thought I'd bookmarked this before -- lots of interesting satellite-related information, and GPS-disciplined oscillator and 9600bps packet modem projects.
