Scott,

congrats to both stations.
As it is a rather northern path condx should even improve when nights beco=
me longer and QRN mower

Onderwerp: LF: JA/VE7 QSO Completed - FINALLY!

  Finally!  After months of trying, our gear, conditions and most of all
our XYL's patience all worked together to produce a QSO!

JA7NI (DFCW30) and VE7TIL (DFCW60) completed a trans-pacific QSO on
2200m this morning a first between Canada and Japan.  CN89dk to QM09fl
is 7162km.

Things started off with a surprise as NI copied TIL's beacon signal
30min before his sunrise.  What followed was a 'quick' exchange of calls
and NI's report was received by TIL.  Then a very long and deep fade
occurred.  This happened before to us and we lost each other and an
entire nights sleep...!  But that taught us a lesson and we adapted to
the deep fading on this path by creating a master slave relationship
between the stations and using QSK to full effect.  Master slave means
the station that is expecting a reply simply waits until he hears it
while the other station transmits until heard with pauses (QSK) to
listen...   NI waited patiently not knowing TIL had copied the calls and
his report.  Our procedure was for him to simply wait until he copied
something...  Three hours later RO appeared on NI's screen and during
one of my crawls out of the bunk I saw a dot during a pause in
transmission and stopped the transmitter.  A few minutes later there was
an R and TU but not in DFCW but rather QRSS as a malfunction at NI's end
had him scrambling, but he recovered with grace and the QSO was in the
bag...

This QSO caps off months of work by both operators in improving their
stations and beaconing on the path to learn its characteristics to make
a QSO possible.  What is clear to me is the trans-pacific path on 2200m
is a very viable communication path for amateur experimentation.  I'm
sure time will demonstrate this further as procedures and equipment
improve on both sides of the ocean.

I would like to particularly thank Yas, JA8SCD (the Tokyo Grabber) for
his help and translation services.  Without him this would have been
much more difficult.

More details including station equipment to follow in the next few days
as I get caught up on my sleep and family life :-)
