Kenwood Month/Year of Manufacture Calculator

Laurie - G6ISY developed the method of calculating the manufacture date.You can find his original work in the files section on the Yahoo group for the TS-2000. http://groups.yahoo.com/group/KenwoodTS-2000/
The file name is: "SerialNumber to Date.txt" How to work out the age of your radio.
Utilizing his information I wrote this javascript to do the calculation. This should work for anything made since 1999.
Below are some example dates and at the bottom of the page is an explanation of the date formats.

You can put more than 3 characters in but the program just ignores them.

 

TS-2000's (Including the X model) in the serial number range 810xxxx - A98xxxx (dates January 2007 - August 2009) were produced with defective filters.
Kenwood has been replacing these bad filters for free. Contact Kenwood National Service Centers for more information.

Kenwood serial numbers issued from 1999 come in 2 formats.

The format used from 1999 until approximately August 2008 is numeric:
First digit is the year code, add 1998 to get year. If first digit is 0 add 10 to 1998.
Next 2 digits are the month code starting with 01 which is April (begining of Japanese tax year).
    Months 10,11 & 12 will be Jan, Feb, Mar of the next year so add 1 to the year.

The format adopted from approximately August 2008 is alphanumeric:
The first character is the decade A=2000, B=2010, C=2020.
The second character would be the year of the decade from 0 to 9.
The third character is the month. 1-Jan, 2-Feb, 3-Mar, ...., 9-Sep, A-Oct, B-Nov, C-Dec.
