Hello Eddie. Yes and the problem was coming for the first time about 3 weeks ago. You can see an example in the join file. All the stations spotted 3 days ago was active using WSPR on the 40 m band.
In complement informations about my last mail : Last month, 5 stations had this problem. and now 4 of them resolved it. GOSLN said he put a wrong transmitting frequency (0.001500) in the window dial
