Hi Domenico,
thanks again for this great experiment. I guess we
were both amazed that it worked so well on MF!
Tonight I am decoding your messages again, and
I'm joining in on odd quarters (21:15, 21:45 etc), using the same format (8K19A,
16 char, 0.5 s).
Best 73,

Subject: LF: COHERENT BPSK ON MF
Hello LF and MF,
I want to report another
successful coherent BPSK QSO between me IZ7SLZ and Markus DF6NM using EbNaut ,
this time on MF.
QSO took place yesterday night 2015-11-15 .
We have exchanged messages of 22 characters in coherent BPSK with UT
synchronous symbols, using a symbol period of 0.3 seconds and 8K19A as scheme
coding. Frequency used was 478480.00 Hz for both stations.
We use low
power for this qso: from my side only 7 W out with an ERP of about 70
milliW. Markus reports his power : "RF power about 30 Watts, antenna
height only ~ 3 m above roof. Probably 0.1 to 0.2 W ERP".
You can see
reported symbol / carrier EbN0 and also the messages exchanged, in the
attached screen-shots taken at both ends.
Some test trasmissions from my
side are planned for tonight.
Ebnaut messages of 16 characters / 0.5 s will
be sent on 478480.00 Hz every 30 min starting from 19.00 until
21.30.
73, Domenico (iz7slz)
