Morse Code or CW has become rare among professionals (in the West). But there is a busy net of small Japanese Fishery Stations literally pounding the brass. One of them is Kagoshima Radio, JFX. They are not daily heard in Europe, but a combination of receiver Winradio Sigma, active antenna MD300DX (2×2.5 m, vertical) and SDRC V3 software did the trick even under this grim summer propagation. See screenshot above, from 24 hours’ recording of 25 MHz HF. All channels clearly readable – as far as the expressive handwriting (see detailed screenshot at the bottom) of their CW allows for … Yeah: CQ CQ DE JFX JFX QRU QSX 6 / 8 /12 MHz K

Reports of the death of Murmansk FAX had been slightly exaggerated … After having searched for it in vain in 1Q/17, it now popped up on 6.328,5 kHz from former 6.445,5 kHz with an irregular schedule, namely at 03:30 UTC at one day and 04:50 UTC another day.
Just fair quality of both, conditions and transmitter, made it very difficult to read the text in the upper part of this weather chart in Cyrillic, with just: Прогноз … 21 час [Prognosis … 21 hour …]. Receiver AirSPy & SpyVerter, decoder Wavecom W-Code.
Also received on June 1st, 2017, but starting at 03:30 UTC – same area, first half of the transmission heavily distorted by an RTTY signal, see below:
Iceberg Prognosis has been received on scheduled 8.444,1 kHz at 20:00 UTC on June 8th, 2017; see below:
Not a trace on/near also listed 7908,8 kHz. It seems that otherwise commendable NOAA publication Worldwide Marine Radiofacsimile Broadcast Schedules is outdated regarding this station.
“HF for the pros is stone-dead, isn’t it?” This rather verdict than question is often heard even by hams. If you are telling them how busy the bands really are (as they cannot read about that in their magazines), they are doubting: “But you need professional equipment plus decoding software, worth my Mercedes Benz?”, they are upset by the answer: “Absolutely bullshit. A software-defined radio at 500 US-$ plus some free software will produce thousands of logs!”
Still don’t believe that? Well, here is the first thousand, caught just in the first half of June, 2016. Received with an FDM-S2 receiver at a quadloop of 20 m of circumference. I mostly concentrated on fixed (rather than: mobile) stations and of modes which can be decoded with free software – if they are not even outright SSB or CW.
You can download this log: Logs_EXCEL from where it may easily be opened not only by EXCEL, but also e.g. free LibreOffice.
If I find time, even more logs from the same HF recordings will be added.
I am greatly indebted to the busy and resourceful friends of UDXF for their work, thanks.
