Thank you! ...Wow...very interesting reading, Roger. Thank you! By coincidence, my current project is a portable 20m CW transceiver intended to be powered by a candle-heated TEG. <br /><br />In the past weeks I've worked across to Europe with the prototype XCVR running 80-90mW and a supply voltage of 1.40Vdc (although not yet candle-powered). The transmitter produces 10mW at a supply voltage of 0.87Vdc. Peter, DL3PB, has been "lighting the way" for me with his candle heated TEG experiments. <br /><br />I intend to carry this radio on my walk across Austria next month. If I don't get the candle power working in time for the trip I'll simply use one "D" cell flashlight battery. Still, I've got my heart set on working "DX by candlelight." <br /><br />Rog, I hope to work you (you too Bert!) next month as OE/AA1TJ. <br /><br />Cheers,<br />MikeMichael, AA1TJhttps://www.blogger.com/profile/11538000826572081873noreply@blogger.comtag:blogger.com,1999:blog-9071048343455395511.post-5779315727618272472011-05-05T21:41:00.152+01:002011-05-05T21:41:00.152+01:00Hello Roger, Thank you for the interesting website...Hello Roger, Thank you for the interesting websites. I read interesting website of Dick with its oscillator with J-FETs and a transformer. Dick has also other interesting things on his web-site if you click on "back to the index".<br />73, BertBert, PA1Bhttps://www.blogger.com/profile/14064917598289627232noreply@blogger.com
