The Backward Music Station was on 6491 kHz.

Until now there were no November logs in the database. Five of the six scheduled transmissions were reported this month. Note that the station now uses its winter skeds.

0700 UTC ? 2100 UTC 7425 kHz
0720 UTC 13434 kHz 2120 UTC 5810 kHz

Packet numbers

Igor copied an unid packet network that sends off-line encrypted messages (5FGs). Ideas about their id anyone?

The network uses a number of frequencies: 7647, 8266, 8566, and 10050 kHz.

Callsigns noted so far: 0001, 0003, 0007, 0011, 0020, 0025, 0028, 0030, 0704, 0705, CASA, BUA

Slot machine

John Maky and Hugh Stegman in the USA, Takashi Yamaguchi in Japan, and John Batty in Australia, all report the mysterious 'Slot Machine'.

John Maky describes the signal as « a continuous pilot tone with 13 tones played over it, spaced in a 4/5/4 group, then repeated. The signal really sounds like a slot machine or computer game. When both freqs are up, it appears to be running in parallel. »

There are probably more stations in parallel on the same frequencies.

The signal appears on 4292, 6419, 6446, 8589, and 8705 kHz. Takashi comments: « very powerful on all frequencies. »

The transmissions seem to come from the East Asia as they follow the reception patterns of New Star BC on 8300 kHz when heard in the USA, while the signal can be heard all day long in Japan. John Batty confirms this with his log:

« At 0730z (local evening in QLD Australia) the signal was present on all 4 frequencies, strength 3, and when I checked again at 1330z, (2330 local) they were all still there, same strength. Throughout, signal strength and signal fading were the same as mainland Asian signals close by in the band (XSG3, XSD, Guangzhou etc). I had 5-second-cycle S3 to S1 fading on all 4 frequencies. Signals from New Zealand and Nandi Aeradio were both much weaker than the "mystery station". I would guess at an Asian location. »

John adds:

« Look at the way they fade in here ... Hope someone can put all the clues together. Baffles me, never heard a signal quite like it. »

Neither did I, John. Needless to says that any info about this puzzle is most welcome. You can download a MP3 sound sample from the N&O website. The MP3 was recorded by Takashi.

xxx7 stations

The unid station that operates on 3007-29007 kHz, is probably a point-to-point propagation logger. We are very interested to hear your comments, suggestions and logs. So far we only received reports from Europe.

A ptp propagation logger usually works with two stations. The first one sends a short burst and if the secondary station hears this, it responds by sending the burst back to the control station. The stations change frequency every ten seconds. The cycle starts on 3007 kHz at hh.07.02, the answer back follows after ca. 0.66 secs, or hh.07.03. At hh.07.10 they jump to 4007 kHz, where the burst is sent at hh.07.12 and the answer back at hh.07.13. At hh.07.20 up to 5007 kHz, etc., all the way up to 29007 kHz. The same cycle is repeated at hh.37.02, starting on 3007 kHz. The system doesn't look very complicated.

The station was discovered by Klaus, who heard it on 5007 and 15007 kHz. About a week later the station was noted on every xxx7 frequency from 3-29 MHz. Both Klaus and a dxer from Central Europe analysed the signals. The characteristics are as follows:

Modulation F1B
Speed 100 Baud
Shift 125 Hz
Bit pattern The station starts with a short steady signal, then transmits a 7 bits character three times and off air with a short steady signal. The 7 bits character has a 3:4 proportion code, all the same. The second station has the same code, but it has less energy at the receiving point.
Location According to the modulation, speed, shift and the code that is used, it might be of Russian or CIS origin.
