I made a short list for those of you not familiar with the call signs and keypad positions.
A-alpha
B-bravo
C-charlie
D-delta
E-echo
F-foxtrot
G-golf
H-hotel
I-india
J-juliet
K-kilo
L-lima
M-mike
N-november
O-oscar
P-papa
I haven't seen any maps larger to need the rest.
example_ If contact was made at bravo-2, keypad or KP-9 we know there exactly in the trees there. Remember that your
keyboard pad is not like a telephone pad. 1,2&3 start at the bottom not the top. Hope this helps!
