Mr. Jón Frímann;

When you talk about any unknown signals,
can you please tell the UTC date and time
and position at which the unknown
signal was received.

Most unknown I have received have turned out
to be mining operations. These will usually be
within 150 Statute miles from me. They will
normally happen during daylight weekdays
and between the hours of 1400 and 1700 locally.

They look like small regional quakes
between 2 and 3.5 in Richter magnitude.
Or so I am led to believe.

I have two (L or S)-P times that are dead givaways
they are like 7 seconds or 25 seconds.

Regards;
geoff
