Hello Bill,
Thanks for watching and the pictures!

Best reception from DK7FC occurred on his last transmission
(0400-0500 enhancement) - looks like there was still propagation
when you pulled the plug Stefan.
Actually i was transmitting my call once again until 6:15 UTC so it
seems that propagation was totally down after 5 UTC in VE.
Which stations did you receive on your QTH so far? Since how many
years are you participating on LF?
Hmmm, let's see... What year were you born Stefan? :-)
I started with Ray Petit's Coherent CW back in the mid '70's on the
Lowfer band. So I guess I've had the bug for about 37 years. My
call then was VE3OBE. Also around at that time were Mark Mallory,
Max Carter, Lyle Koehler, Herb Balfour and many other avid
LF-ers. It's hard to remember exactly which year I started. My QST
article on DSP was published in Jan '82, then there was a QEX article
about using a digital technique instead of hardware "integrate and
dump" filters to copy Coherent CW. I haven't kept many QSL cards but
just had a quick look: found one from Rick, VE3OXX who received my
"IQ" beacon (187.5 Khz) on July 13, 1993. I still have a QSL from
Bill Cantrell dated January 1st 2000 for my reception of his "TX
space" beacon (QTH Haslet, TX) on 189.700 Khz. It might interest you
that Bill was using an atomic clock (Rb oscillator) for frequency
stability and I was using a GPS-stabilized frequency standard at the
Rx end and the mode was BPSK MS100 (100 msec per bit). Lest you
think we're breaking new ground with this trans-Atlantic QRSS stuff,
let me assure you it has all been done many times before! For
example: in February 2004 I was able to pull a complete callsign from
CT1DRP out of the noise on 135.9245 Khz. Brian was sending his
*long* callsign using FSK with ASCII encoding, one minute per bit
with the start of each bit synchronized to the start of each UTC
minute and I used GPS timing at the Rx end. As I recall, Andy G4JNT
also copied his transmission at that time. Not to forget Larry
Kayser VA3LK and Laurie Mayhead G3AQC who completed a 2-way TA LF
contact in February 2001. The QSO took time :-) If some particle
actually travels faster than light, now that would be real news!
73,
