Todd Gale, VE7BPO, is a true HOMEBREW HERO. His QRP POPS website<\/a> has been a source of inspiration and information for many years. Todd wrote in yesterday on the trivialization of regens and what we should do about it. Thanks Todd! <\/b> <\/p>\n

Dear Bill:<\/b><\/div>\n

<\/b><\/div>\n
With due respect, I challenge the statement that many feel regenerative receivers are trivial. I submit that most of us know that regens offer good sensitivity + selectivity despite their few parts, however, we ourselves, may trivialize the regen by our lack of literature reviews, experiments, imagination and attempts to improve its downfalls.<\/b><\/div>\n

<\/b><\/div>\n
Where are the bench experiments and inspired discussion that address issues like designing circuitry to reduce overload and blocking while still maintaining high sensitivity when needed, hum + noise reduction, AF filtration, or ways to reduce RF pollution into the RF lab environment? <\/b><\/div>\n

<\/b><\/div>\n
Much work on regens and of course, its amazing sister, the super-regen dots the literature. People did make many experiments to explore topics like vario-couplers, litz wire coils with low applied power regen detectors, sensitivity analysis, noise analysis and frequency domain calculations. <\/b><\/div>\n
We now tend to see or present \u00fcber basic regenerative receivers complete with LM386. Yet, still we authors somehow feel people might not respect the regen? Really?<\/b><\/div>\n

<\/b><\/div>\n
Another factor: as my regen grows in complexity, shouldn\u2019t I just make a zero IF radio (now just as simple with a dongle or two I\/Q mixers going into sound card), or perhaps make a simple superhet with some computer crystals for the IF filter?<\/b><\/div>\n

<\/b><\/div>\n
Regenerative receivers remain cool. Perhaps putting both hands on the controls plus the antenna coupling are just part of the regen experience and like a standard versus automatic transmission, offers more visceral listener engagement? <\/b><\/div>\n

<\/b><\/div>\n
No doubt, nostalgia and love for simplicity color the regen experience. Now is the time to make a regen \u2014 If you listen carefully \u2014 inside many big cities the crashing sound you hear is yet another SW tower coming down. <\/b><\/div>\n

<\/b><\/div>\n
Hats off to you Bill and also to Dave, AA7EE for his stellar blog presentation.<\/b><\/div>\n
