    Default Yaesu - Year of Manufacture?

    Is there any chance of determining what year an FT-1000D with the serial number of 0F040138 was manufactured? Seems like it could be 1990 or 2000. The FT-1000/D radios were made between 1989 and 2003 according to information I have read on the Yaesu Museum site. I suppose I could call Yaesu, but thought I'd ask here first. Thanks.

    Default yaesu serial numbers

    Simple breakdown of the Yaesu code is below:

    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

    Position 1 = last digit of the year in which the radio was produced
    Position 2 = month made
    Pos 3 &/or 4 = lot number(s)
    Pos 5<-8 = sequence in that lot

    I'm not sure you read through and understood the actual inquiry in my post. I completely understand the breakdown of the serial number structure and digit placements.

    My problem is with a serial number FIRST DIGIT of ZERO - which could signify either the year 1990 or the year 2000 (big difference to me). This radio was made in both of those years. I thought I explained the above pretty clearly the first time.

    So perhaps I will call Yaesu and see if they can make a determination.

    Thanks anyway.

    You might get lucky and find dates on some components that would narrow down the decade.

    That's what I would do. Pop the cover and look at a few chips. They will usually be date coded with YYWW, a 4 digit number, like 8821 or 9716. Sometimes the coding is a little different, but the first two digits are usually the year.

    If you find two or more components with the same year coding, you can be assured that the radio was manufactured during or after that year. Rarely are really old parts used, so the coding will almost always be in the year of manufacture, or possibly the year or two before.

    This picture shows a chip with date code 9341:

    Tom and (JEM), thanks so much for the suggestion. Great idea, and I'll give the inside of the thing a good visual inspection anyway. (It's a radio that is still on the way).
