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!
