[Moon] QSO or not?

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.

   >05:19:16 DH7FB frank gerard, so the received "ro" came fm another stn maybe
