I'm going to run the U3 in WSPR15 at 100% starting at 1645z as I continue driving around looking at relative FS. About .5w ERP... 474.2 dial freq with carrier up around 475.822. I will go to WSPR2 mid-afternoon and expect to call CQ this evening on CW starting around 0200z... details on that later. 73! John XIQ
