Congratulations to you both, the tough part is
over, it's only going to get easier now. I'm sorry now I didn't stay
up to watch and listen to this historic event.

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 :-)
