RTTY-HF-RTL-SDR

[xfactor99]

Hi,


finaly today I got my first RTTY HF reception.
Transmitting from Hamburg in Germany to Alicante in Spain

Here the result:

   

They offer weather for the Atlantik, North-Sea, Baltic and East/West Mediteranean

The Programm/Times and frequencies you can find here:

I used:
Pi 4
OP2
RTL-SDR- wide with HF connected to my Backstay-Antenna
GQRX (Installed with OP2 SDR-VHF Installer)
FLDIGI installd over command line


The steps were,
1: to get an FM-Radio station to play in GQRX
2: Tune in an HF-Signal like RTTY or Weatherfax in GQRX
3: Get FLDIGI to decode an Weatherfax from an audio (wav) file
4: Get the HF-Signal from GQRX into FLDIGI
5: Find the right Settings for RTTY-Mode on FLDIGI

At the end it was a lot of trying and testing and I´m still not verry shure how to reproduce ...

From this point it should be a short stepp to get Weatherfax decoded, also my harbour with all the
Masts and Mountain is not a good palce to receive.

Save sailing to all
