What are the Tones on 14.077 ?
Hi
I have been using Multipsk for a while, there are tones around 14.077 which sound like a slow MFSK. I have tried copying them without success using MFSK16,MFSK8, Domino etc. I seems slower than MFSK16/8. Any idears ? TIA |

The signals appear to be JT65A |

The signals appear to be JT65A Had the same problem here. Tried many different programs to decode but all of them failed. In QST there was a notice about JT65 being used on HF, and this link which helped me to have my first JT65 QSO within a few days: http://obriensweb.com/bozoguidejt65a.htm To see who's currently active in JT65 and on what frequency, check http://www.chris.org/cgi-bin/jt65talk 73, Markus |

Tried out JT65 tonight and just had a local repeatedly replying OVERDRIVE OVERDRIVE whilst I was running 20W from an FT1000MP a 100W rig, no ALC and low SWR ????. Still have a lot to learn. 73 |

TIA Those tones are from the FT65 mode that is used with the WSJT weak signal software. The calling frequency is 14076 or there about. W0TUP |
