Homebrew Adventures with JT65


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.
