[Yaesu] Serial Number Information - FT-847 and FT-100D

[Jim Gerke]

The Yaesu serial numbers can be decoded as follows:

The first character (a number) indicates the year of manufacture.

The second character (a letter) indicates the month of manufacture.
Subtract two (2) from the letter's position in the alphabet to determine
the month.

The next two characters (numbers) seem to indicate lot number in some
cases, or are part of the manufacturing sequence number (see next) in
others.

The last four characters (numbers) are the manufacturing sequence number
of that radio.

So, for example, a serial number of 2H015678 would indicate that the
radio was built in 2002 (the 2), in the month of June (H is the eighth
letter of the alphabet, 8 minus 2 = 6, the sixth month is June), was
part of lot number 01, and was unit number 5,678 built in that lot. 

Obviously, the year digit could mean 1982 or 1992 in addition to 2002.
Apparently the assumption is made that anyone interested in decoding a
serial number is capable of determining which ten year period the radio
was built during.
