Dear Jimmy,
It is an honour to me that you think I make no mistakes. However unlike you and some others I am not perfect. The answer to the noise you´re making below is rather simple. I made a typing error. This can happen, independant from the mode of the QSO or NO-QSO.
I am currently on business travel and will have access to the paper log only this weekend when I am back home. I will then correct the log on my website.
I have never ever had problems with decoding single tones messages but every little mistake seems to serve as a wonderful platformfoor those interested to intrigue against WSJT and DS in particular. BTW I also made a typing error with Jan DL9KR´s 70 cm CW qso which I printed as 10z instead of 11z.
I hope this clarification comes early enough for Peter SM2CEW´s "The world ist a disk" blog, before he starts using my typing error again as an argument against JT65 DS in toto.
Of course if it had been a cw QSO and I had made this typing error, nobody would have written an email o the reflector.

>ON4KST logger:

>operation, you gave a lot of stations a new DXCC
>05:24:05 DH7FB frank gerard, yes in next time we will also do this
>05:19:50 PE1BTX Gerard 4X12/QRO Frank, could be, pse look my EME log
>http://www.pe1btx.nl/EME%20initials%20all%20bands.htm
>05:19:16 DH7FB frank gerard, so the received "ro" came fm another stn maybe
>05:16:17 PE1BTX Gerard 4X12/QRO Yep, NC for me, but already wkd ZB2IQ back in
>1983 on ES, and confirmed
>05:13:57 PE1BTX Gerard 4X12/QRO Found my QSO complete in the log, but never
>send RO to him on 21st, so not complete for me, did not even had a decent decode
>on 21st, very strange
