3 transistor SSB transceiver

http://www.intio.or.jp/jf10zl/3trssb.htm

The website of Kazuhiro Sunamura JF1OZL is magic and contains some superb ideas for QRP enthusiasts. Every time I return to this site I find something to enjoy and to inspire me. Take for instance the 3 transistor 6m transceiver he describes: it is wonderful. Kazuhiro San, if you read this THANK YOU for your great ideas.

A crystal set transceiver?

JF1OZL has some fascinating ideas on his inspiring website. Typical of his wacky ideas is his 20uW TX for 7MHz powered only by the human voice bellowing into a mic. I wonder if a crystal set transceiver is possible using either the rectified human voice (as per JF1OZL) or rectified received RF to power a micropower TX working alongside the crystal set RX? Even a 0.5uW TX could cover miles on VHF line of sight with a beam and generating this sort of power should be possible through rectification of MW and lower HF broadcast stations.

JF1OZL - still the best!

http://www.intio.or.jp/jf10zl/ is a magic site if you are keen on simple QRP homebrew radios. Kazuhiro Sunamura has such a creative talent and I just love his hand-drawn schematics and layouts. He has a unique ability to turn a few components into a fantastic QRP SSB, DSB, AM or CW transceiver. Not to be missed!
