Ken,
As for the exchange during a QSO, normally just the first 4 digits.
For microwaves use all 6 as the bearings are more critical with dishes
that might have a 3 degree beam width or less. I have all 6 printed on
my QSL. If you are using one of the logging programs for contesting (WL
or free N1MM) or otherwise and enter the 6 digits for both stations and
it will give you the distance in miles or km, bearing and reverse
bearing (his bearing to you). Using all 6 gets you within about a 2.5
mile square on each end. Using 4 and it figures to the center of the
grids. The program is also available free otherwise from N0UK. For
instance in the 10 GHz cumulative contest the QSOs points for each QSO
are the distance between the two stations in km. Using all 6 gets you
within about 2.5 miles. Another feature of the 10 GHz contest is if one
station moves 10 miles, you can work again so you have some stations
sitting on top of Pikes Peak or Mt Evans and rovers tearing up and down
north south roads in Eastern CO stopping every 10 miles to work the
mountain toppers. It is possible to get over 200 points per QSO. There
may be only 10 to 15 different stations but you can make over 250 QSOs
in the contest.My home designator is DM69em. If I put KD0AGV in N1MM in
a VHF contest window and enter DM78qr for your grid, it shows me the
distance is 170 miles, bearing 108 degrees and reverse of 288 for your
heading to me. I could have chosen km in N1MM like is used everywhere
else but Burma and the USA and it is easy to change back and forth.
I don't know a really good source of how to DX on 6m but EA6VQ's web
site is good
> http://vhfdx.net/
It really helps to use one of the online spotting sites like ON4KST,
EA6VQ or VE7CC. EA6VQ has a lot of info on his site and explains a lot
about using the digital JT65M mode used for weak signal or EME. JT65M
was developed by Joe Taylor, K1JT (a Nobel prize physicist at Princeton)
and not only did he develop it, he is also a regular user in VHF
contests. It is to the point where a modest station on 2m can make EME
contacts with 150w and a single yagi. There is another version for
working off meteor trail and it is all free ware. It is similar to using
PSK on HF. If you can do PSK or RTTY, you have the equipment already. As
for what is going on at this moment on VHF in the world, go to the real
time maps on EA6VQ and select 6m or 2m and Europe, North America or
world. It is neat to see your call show up on the map after a QSO gets
spotted. It will also show a line to the other station and his call if
the map isn't too busy.
