How to decode Yaesu serial numbers

If you need to know exactly when your Yaesu radio was manufactured here is the way to decode Yaesu serial numbers:

Position 1 = year made

Position 2 = month made

C = January
D = February
E = March
F = April
G = May
H = June
I = July
J = August
K = September
L = October
M = November
N = December

Pos 3 &/or 4 = lot number(s)

Pos 5<-8 sequence in that lot

Position 1: last digit of the year in which the radio was produced

Position 2: Determine the position of the letter in the alphabet (C=3,D=4,E=5, etc) and then subtract 2. The result gives the month in which the radio was manufactured. Note that the letters will range from C (January) throughN (December). Thus, a radio with a serial number of 5H221234 would have been manufactured in 2005 (5), during the month of June (H=8, 8 minus 2 = 6, June is the 6th month), was part of lot 22, and was the 1234th radio in that lot.
