You know, if one could get accurate delays from a number of locations,
one could triangulate its location - just thinking. :-)

Hello,
I'm receiving, maybe from less than a month, a new station on 10 MHz
which claims it is an "experimental time signals station".
The weird thing is that they transmit music between the minute time
marks, heavily interfering with the other standard stations which
share this frequency. Currently I receive there WWV, the Italian
official standard frequency and time station IBF and its Brazilian
counterpart PPR (BTW PPR broadcasts local time instead of UTC). They
transmit continuously 24 hours a day.
Every 15 minutes a female voice says that this is an experimental
time station, gives a web page and its locator. While I agree that
anybody could run an standard frequency and time station, given
official license from their local authorities (and after
international coordination, I suppose), I think this is a truly
"pirate" station because among their weird "programming" , I also
notice:
- Their carrier is currently - 4 Hz off.
- The second ticks are offset enough to be perceived by ear with
respect to known standards.
The transmission is in USB with full carrier (I don't have the
designation on hand). The format is:
- The whole sequence begins at multiples of 15 minutes.
- At second 52 they transmit something like a 2 second burst in FSK
(It can be a fake signal without any useful information).
- At second 54 begins 1 sec ticks.
- Tick at second 59 is omitted, then only the tick for sec 0 is
transmitted.
- After the 0 sec tick a male voice announces the hour and minute.
The voice has an intonation like a news or sports speaker.
- A female voice makes an announcement about being an experimental
time station, gives a web page and its locator.
. The ticks are discontinued and replace by music.
- The first music in a 15 minute cycle is from Peer Gynt, it is
replaced with other music the next minutes.
- The next minutes lack the female voice announcement until next
cycle begins.
All speaking is done in Italian language.
If I copied the locator correctly, the transmitter location is near
Pisa, Italy.
Did anybody noticed this transmission? I receive it in Madrid, Spain.

Ignacio, EB4APL
