Hi Walter,

I have just finished putting up a 6m square loop to measure the field strength
of the signal on 136.00.  If your signal is the same one as mine, mine bears
015 +/- 10 degrees from me which logically puts it in the NW corner of Spain.
With me there is absolutely no night day variation and the field strength
calculates out at 2uV/m if I have got all my arithmetic and physics right.
Putting guessed values into Reg's groundwave3 programme puts the
distance at 300km.  More data on my web pages and would value your
opinion.

I shall get out my loop and take a bearing but it's extremely weak here.
If it's a Navy station in Spain I would have expected a far stronger signal.
Also, not aware of any LF sites in NW Spain. The only US Navy tx site
near you is Rota (Cadiz) but I don't think it does LF.

If you put yout signal on 135920/5 perhaps my data logger may pick it up.

ant so probably only a few puny microwatts radiated.
