The VFO part was designed on Chiloe Island, the IF and receiver circuit took shape at Futaleufu, Rio Cisnes, Puerto Aysen and Coyhaique, while the difficult RF power amplifier work was done on the return trip via Bariloche in Argentina. <span style=\"background-color: yellow;\">So this is an international design!<\/span> Once back at home, for the first time in my life I did a thorough computer simulation of the whole thing. I hacked around the program for two weeks, and then my poor Atari had to spend another two weeks crunching numbers. It found some potential problems. I improved gain distribution, corrected mistakes, and then went straight to designing the printed circuit board, without doing any real-world test.<\/b><\/i><b> <\/b><\/div>\n<div> <b><br \/><\/b><\/div>\n<div> <b>Check it out: <\/b><\/div>\n<div> <b><br \/><\/b><\/div>\n<div> <b><a href=\"http:\/\/ludens.cl\/Radiacti\/Radiacti.html\">http:\/\/ludens.cl\/Radiacti\/Radiacti.html<\/a><\/b><\/div>\n<div> <b><br \/><\/b><\/div>\n<p> <i><b><br clear=\"all\" \/><\/b><\/i><u><\/u><sub><\/sub><sup><\/sup><strike><\/strike><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Greg VK1VXG sent me this link.
