I was hoping to use this rig to make at least a few PSK-31 contacts. But I started seeing these strange looking sigs in the waterfall. I found out they are JT65 (JT for Joe Taylor). So I downloaded the program JT65-HF. I got the receiver going very quickly (it is a 40675 dual gate MOSFET followed by the audio amplifier out of Roger Hayward&#8217;s Ugly Weekender RX). The transmitter is just a two diode singly balanced modulator followed by the RF chain from Peter Parker&#8217;s Beach 40 Rig. QSOs seem imminent. <\/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>My six dollar DDS board hasn&#8217;t arrived yet, so this weekend I worked on the re-build of the 30 meter Direct Conversion\/DSB transmitter that I built in Rome (originally for WSPR use).
