- I just thought that I would add that I just picked up the Feb 93 issue
- of Popular Electronics today and it has an article about building amps
- with the MAR series. "Antenna Amplifiers That You Can Build" by
- Joseph J. Carr, pages 43 to 46. Of couse, it's all (C)1992 by Popular
- Electronics, so I can't reproduce the diagrams here. :)
