Re: LF: EbNaut DF6NM last night

[Domenico IZ7SLZ <iz7slz.domenico@gmail.com>]

Hello LF,

attached the results of EbNaut transmissions of IW4DXW and DF6NM last night.

Riccardo has reported an antenna mismatch tonight (due to the snow) that reduced its power output.

Stefan, thanks for the hint! Since 23 UT, Riccardo IX4DXW and myself are sending hourly EbNaut messages (8char, 2sec, 8K19A) on 137485.0006 and 137490.000 Hz respectively.

Best 73,
Markus (DF6NM)

Hi Markus,

It may be useful to put Vasily into the adress list :-)
Maybe he will get you.

Thanks a lot, Alex and Domenico!  Receiving your reports indeed makes me happy ;-)  

Good to see Ric back on again now. I'll also join in later tonight on 137490. Of course it would be very rewarding if distant receivers like VO1NA or UA0SNV were able to pick us up!

Joe, with the current scheme we may not even need the pilot injection: As soon as one of our carrier preambles or postambles becomes detectable, we can derive your exact RX frequency, and apply the correction also to all other TX stations in the same time slot.

All the best,
Markus (DF6NM)

Hello Alex, Markus, LF

DF6NM's Ebnaut signals have been decoded also here in South Italy as follow:

QTC: BE HAPPY

UTC      Eb/N0 [dB]   Eb/N0 (fm carrier)   BER         dF  [Hz]

00:00     14.3               18.5                    2.7%       0.0001

01:00      5.0                6.7                     25.6%      -0.0005 ??
02:00     71.6               23.5                   0%           0.0003

07:00     15.5               19.7                    1.4%       0.0003

No differences in the time offsets respect to the nominal declared.

Transmissions from DF6NM before 00:00 were not recordered due to other task in progress (sri Markus).

Wave files of these recordings have been uploaded now in the folder
