Peter Parker's amazing 8 transistor DSB rig (featured in an equally amazing YouTube video -- see earlier blog post) has sparked a worldwide resurgence of QRP minimalism. There is now a lot more activity on the "Minimalist QRP Transceivers" Yahoo group (be there or be square). Steve "Snort Rosin" Smith WB6TNL is minimalist mentoring to the max -- with his help it looks like more VK3YE transceivers will soon be on the air. Steve was kind enough to take the info from Peter's video and turn it into a .pdf schematic (see above). It is in the file section at the Minimalist QRP Transceivers group. I was, of course, pleased to see the inclusion of a robust 7 element low pass filter.
Michigan Mighty Mites are also tickling the ether. I may pull out my single MPF-102 Yingling 80 meter rig. You can join the Minimalist group here: http://groups.yahoo.com/group/Minimalist_QRP_Transceivers/

Hi Bill,
ReplyDeleteIt was my pleasure to be able to contribute to the project. I've been corresponding with Phil Storr VK5SRP and asked him to double check my drawings. Sure enough, he found an error! Check the earbud jack and you'll see that not only did I short across the earbuds but there is no ground return on the jack.
Another beautiful design is spotto on ham radio India and it performs much professional.......
ReplyDeleteGood rig!
