Hi Markus and LF,

i think that your previous email was not distributed.

Many thanks for the signal. FB copy here with a monster Eb/N0 without errors.
Decoded "DF6NM 73"
Time   Eb/N0
22.00   71.6 dB
23.00   71.6 dB

I will report the other transmission results  tomorrow and i will post the wav files in my small web-site.

73 and good weekend all !

Domenico, iz7slz

Hi Domenico,

here are the EbNaut parameters. I've already sent those through blacksheep, but unfortunately I usually do not get my own mails back so I don't know whether the reflector has really distributed them.

Best 73 + GL,
Markus

To obtain some extra sensitivity, I have now slowed down to 2 seconds per symbol, with transmissions starting 0.3 s after each full hour.

Frequency 137490 Hz,
8 characters, 8K19A,
2 second symbols (duration 21m52s)
Start times: 22:00, 23:00, etc. until 7:00 UT, plus 0.3 s transmit delay.

73, Markus
