Hi Joe,

that's great news - yes we are surely keen to look for our signals in your recordings.

Dom's and my 29 minute transmissions started on the hour, so the best files would be the ones centered near hh:15. Ric's transmission was somewhat shorter. From your list, I'd probably select the ones ending in xx:10, which are 

12172210.txt,
12172310.txt,
12180010.txt,
12180110.txt,
12180210.txt,
12180310.txt,
12180410.txt,
12180510.txt,
12180610.txt.

Did you still employ the DDS pilot injection to guide us to the right frequency? Last time the pilot was more than 50 dB above the noise, which may have reduced carrier-EbN0 readout and affected decoding. For future sessions, I'd recommend to reduce the pilot level by about 20 dB.  

We'd also need to know the result from your samplerate calibration (1200x.xx Hz). This was displayed during the calibration - if you hadn't noted it at the time you can still read it from the audio correction table or from mconfig.ini.

Was the PC clock steered by NTP or some other means?

Best 73,
Markus

Hi Domenico and Markus,

Here is a list of EbNaut files. I can upload a few of them
if you would like. Let's hope SR and FO were properly engaged!
There is a compiled ebnaut on this unix box that I should be using too.
