Just make up a loop and use a compass to get a bearing from a few places. That
should place it close enough a local member could do the same by driving around
and nail it.
I did that to find a CODAR transmitter.

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
