1/2 hour between grid switches, stops grid circling in mass. This means
staying in a grid for atleast 1/2 hour. I try to stay one or 2 myself.
Distance modifier calculating.
If you are in dn 13 and work dn 14 it would be one for the distance modifier
X the grid classification. If you worked dn 17 it would be four x the grid
classification. if it was dn 27 it would be five x grid classification.
Basicly subtract the one grid from the other but subtract the 10's first then
the
ones next dn 27 - dn 13 would be (2-1) + (7-3) or just count them on a map
without going diagnaly, like a rook on a chess board. Do not count your own
square. ( 10 is the limit). Also when you change Prefixes ie cn to Dn the lower
number must be considered 10+ the number. IE CM 99 next to Cn 90 is (9-9) +
(10-9)
= 1
The easiest is to count it on a grid map, free from Icom on the internet. I
imagine software would come along if the contest works. You can write down the
grid and do the math later after the contest.
I hope it would be easy after a while, IE cn84 to CN 96 is up 2 and over one
therefore it has a distance modifier of three.
The guy in cn 96 will say he's down 2 and over one he must be 3.
