Three simple AM transmitter plans for Part 15 broadcasting

Back in the not-so-distant past the primary mode of transmitter diaspora was electronics magazines articles by circuit gurus like Rudolph Graf, William Sheets and Doug DeMaw.
     If you missed an issue with a great circuit, you could always order reprints for $2.00.
     The bad, and somewhat ironic, news is that the publishers of electronics magazines couldn't adapt to the new electronic publishing environment brought about by the medium we are using now and all those stories publications have perished.
     The good news is that an enterprising person has resurrected all of those dead issues in a delightful site called American Radio History
     Having been an avid reader of our dearly departed physical media, your faithful editor was able to take you back in time to bring back some great little Part 15 AM transmitter projects featured in that chosen medium of yesteryear.         
     So with that in mind, please to be enjoying three low power AM transmitter circuits from 80s and 90s electronics magazines.
     Parts lists included but you'll likely need to do some substitutions - more's the fun!

Doug Demaw's "Mini Broadcaster," with five 2N2222 transistors in this intermediate level project, Monitoring Times, December 1996

Doug Demaw's "Transmitter Basics," featuring a low parts count for this intermediate level project, Monitoring Times, October 1988

Joseph Smolski's "Build a 1930's transmitter," A tube powered mini-transmitter with fewer than 20 components for this beginner level project, Popular Electronics, November 1991
     
     So grab some of the new lead-free solder, heat up the iron and make some radio! Lots of articles on this very blog about antennas you can use to extend range.
