My six dollar DDS board hasn’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). 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’s Ugly Weekender RX). The transmitter is just a two diode singly balanced modulator followed by the RF chain from Peter Parker’s Beach 40 Rig. QSOs seem imminent.

Glad to see you have the JT bug Bill. I love this mode. Current record for me is Chicago -> South Africa with about 400mw using a random long wire tuned on 40meters. Incredible mode and I cannot wait to hear how you do with it! W9PDS
You probably already know this mode requires accurate time. I run NTP on my Win7 machine, but used Dimension 4 on my XP. Also, we usually use JT65 with a computer controlled rig, so you’ll be doing some manual operations. You want to check out JT-Alert. It is a super handy application that runs with JT65, and makes operating much more fun. Enjoy; I hope to see you on the air! 73, Steve W1KF
