Although I was following this thread and posting to it, I have missed what
the current tranmission mode is--when I loged them years ago, I copied
Baudot FSK with ID.  But now here in Virginia south of Washington DC on
about 139 and 129 late at night, I hear a weak carrier with a "noise" burst
about every 10 seconds or so (no timed).  This is using my rooftop 1/2
meter E-field probe. I finally dug out my notes from my summer 1999
Netherlands trip with LF/VLF (I appologize to those to whom I promised to
do this earlier but currently I have "time problems".)  I see that I heard
the same signals when I was in Utrecht, south of Amsterdam.  While there, I
took bearing using my home-made ferrite loops (raising the curiousity of
early morning visitors to the same park).  The bearing there were
approximately consistent with DCF49 on 129.1 kHz and the ITU listed Burg
DBF39 site on 139.1 kHz.  However, on that trip I could only resolve
frequencies to the nearest kHz.  Anyway, what are the current
characteristics being heard in Euorpe for the 129.1 and 139.1 transmitters??

Additional, while in Europe, I heard data bursts on 144.6 and 131.7647.
According to ITU, there are various tranmsitters in the Netherlands/Belgium
on these freqs.  Anyone know what these are?
