I made use of the additional shack time to test the feasibility Farhan-izing my old, not-so-beloved Heathkit SG-6 signal generator. I did a quick Manhattan build of the oscillator section from Farhan&#8217;s sig generator (link in yesterday&#8217;s post). Using an idea from an old 73 Magazine article on a similar project (thanks Clint!), I smashed the tube (appropriate, don&#8217;t you think?) and connected (using the glass stump!) Farhan&#8217;s oscillator directly to the pins that lead to the switchable coils and the variable cap of the SG-6. I just wanted to see if it would oscillate, and see if there was a big change in SG-6 dial calibration. <\/b><br \/> <b><br \/><\/b> <b>Wow, it worked great! It oscillates very nicely on all but the upper frequency band setting (20-50 MHz). I feel confident that I&#8217;ll get it to oscillate at least up to 30 MHz. Next I&#8217;ll build Farhan&#8217;s buffer and amplifier stages. The SG-6 had a switchable attenuator &#8212; I want to include that feature in the solid state version. I&#8217;ll have to give some thought to the audio modulation feature (nice for aligning AM receivers). <\/b><\/p>\n<div class=\"separator\" style=\"clear: both; text-align: center;\"> <a href=\"https:\/\/www.homebrewradio.us\/blog\/wp-content\/uploads\/2012\/11\/P1010101F.jpg\" imageanchor=\"1\" style=\"margin-left: 1em; margin-right: 1em;\"><img loading=\"lazy\" decoding=\"async\" border=\"0\" height=\"320\" src=\"https:\/\/www.homebrewradio.us\/blog\/wp-content\/uploads\/2012\/11\/P1010101F.jpg\" width=\"239\" \/><\/a><\/div>\n<p> Our book: &#8220;SolderSmoke &#8212; Global Adventures in Wireless Electronics&#8221; <a href=\"http:\/\/soldersmoke.com\/book.htm\">http:\/\/soldersmoke.com\/book.htm<\/a> Our coffee mugs, T-Shirts, bumper stickers: <a href=\"http:\/\/www.cafepress.com\/SolderSmoke\">http:\/\/www.cafepress.com\/SolderSmoke<\/a> Our Book Store: <a href=\"http:\/\/astore.amazon.com\/contracross-20\">http:\/\/astore.amazon.com\/contracross-20<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We have kind of half a holiday today &#8212; I have the day off, but the kids went to school.
