I finally got the little 30 meter DSB\/Direct Conversion transceiver that I built in Rome working on PSK-31 and JT-65. It features a VXO circuit from George Dobbs, an AF amplifier designed by Roger Hayward, and an RF amp chain designed by Peter Parker. It produces about 1 watt of RF. At first I was manually switching the rig from transmit to receive, but this got old real fast, so I built a little VOX circuit &#8212; the AF from the sound card does the switching. Last night I fired it up on PSK-31 and stations were calling me (including one fellow in Cuba). Then I went to JT-65 and had a complete QSO with KT1B. Another this morning with K0ASK.<\/strong> <strong> It is kind of fun to combine the simple (this rig) with the complex (the computer and these digi modes). I find that I can work both JT65 and PSK 31 while keeping the VXO at 10.139 MHz. <\/strong><\/p>\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>It&#8217;s ugly but it gets you there.
