The Complete Bozo's Guide to HF JT65A
The first HF terrestrial use of JT65 appears to have been a JT65B QSO on August 14 2006 between Victor UA0LGY and Tetsu JE5FLM. The recent explosion of HF activity began after VE3FGU , and several of his friends, started experimenting with the JT65B on March 23 , 2007 and JT65A on March 24. 2007.
On March 28th, several members of the digitalradio reflector (http://groups.yahoo.com/group/digitalradio/ ) noted some unknown digital signals on 20M and on March 30th concluded that they were JT65A signals . The experiments of Mike VE3FGU, Tetsu JE5FLM, David WD4KPD, Marshall W9RVG, Seli TF3AO, and others, quickly exploded in to the hottest HF mode for weak signal DXing and experimentation.
