Thanks so much, Stefan! Yes, sorry but I turned off the TX prematurely (I was going out to work). Maybe I will try again tonight on the same QRG (or another: any suggestion?). I also could increase the symbol duration, so I'd have a better chance in a DX report.

All the best

Hello Riccardo,

Here is your decode from here. I just tried the 7 UTC message. Of course no problem but it looks like it stopped a bit early.
Good luck and let's hope for some more professors.

Jay and Stefan,

 

I attempted my first over the air EbNaut decodes last night using two separate receive systems.  All appeared well but find that both instances of SL did not save the entire wave file for each receive period but truncated it to about 165K.  Will play with that today as have not experienced that in previous end-to-end sessions in the shack.

 

Well done and thanks for putting the EbNaut signal on the air, Stefan.  Thanks for posting yours, Jay, as it confirms I should have been able to copy all.  Look forward to another opportunity.

 

73,

Copy of your message below. The message is not blacked out since it was already available on Marcus's automated decoder. Nice to see rank 0. Will be looking for Marcus next!

PS: The message is transmitted from a SpecLab instance. So you need to consider the +0.3 second time offset, which is relevant at that symbol length. Furthermore there is some uncertainty if the transmission starts at the exact second. It could happen that it starts 1 second to late. We will see what happens.
