I *think* I have been chased by a QRO++. But I am sure that Jerry wasn't QRO, and for some bizarre reason I can't decode him and vice versa. I suppose this is the inevitable consequence of playing with new protocols.
JT9-1, like all the JT protocols, looks exciting for QRP DX hunters. Minimal bandwidth, and really QRP operation.
But I have nothing in my log to prove it!!
