Re: AGC Circuit for uBITX Featured in July 2019 QST Magazine
¿ªÔÆÌåÓýAs I recall, the JackAl AGC circuit is just the Hycas AGC circuit lifted from QST December 2007.? Al added a couple of things like a switch to turn it off.? The FETs are nothing special.? A 201 and a 102 will work fine. ? ? From: [email protected] [mailto:[email protected]] On Behalf Of Rob French (KC4UPR) ? I'm looking at possibly lifting just the AGC circuit out of the JackAl design, and seeing if I can stock it out of my junk box.? But... the only JFET's I have are MPF102, J201, 2N5486, and 2N4393... will any of those work?? Other than the MPF102, the rest were all originally purchased for audio work, so I can totally imagine them not being suitable. -- ¡_. _._ |
