[Yaesu] FT-1000 Serial Numbers

[Jim Gerke]

Don,

The following is the text of a post I made last November and should
answer your question (see last paragraph).

Here's the info on Yaesu serial number decoding. 

All characters in the s/n are numbers except for position 2 which is a
letter, C through N.

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,....., N=14) and then subtract 2. The result gives the month in
which the radio was manufactured. Note: a straight vertical line in this
position is a capital "i" (I), not the number one. 

Positions 3 & 4: The lot or run number.

Positions 5 through 8: The manufacturing sequence number of the radio.

Thus, a radio with a serial number of 5H123456 would have been
manufactured in 1995 (5), during the month of June (H=8, 8-2=6, June is
the 6th month), was part of lot 12, and was the 3,456th radio in that
lot.

One other thing I learned just recently...... The FT-1000/FT-1000D were
produced over a 12 year (or so) period. Thus, a 2 as the first digit
could mean that the radio was built in either 1992 or in 2002. To
distinguish between the two years, the letter "A" is appended (with a
rubber stamp) to the s/n sticker of the unit built in 2002 to indicate
that it's the second use of that s/n. 

As far as I know, the serial number of the unit does not appear anywhere
inside the radio.

Given that the Yaesu serial numbers start with a digit indicating the year, continue with a letter indicating the month, 2 digits for the lot, and 3 digits for the number within the lot.  How can you differentiate between an FT-1000 manufactured in 1990 and one manufactured in 2000?
