Kenwood Month/Year of Manufacture Calculator

Laurie - G6ISY developed the method of calculating the manufacture date. The file name is: "SerialNumber to Date.txt" How to work out the age of your radio.

Utilizing his information I found this fantastic javascript written by someone else (Tim?) to do the calculation and 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.

Good Filters	Defective Filters		Good Filters
301xxxxx = April 2001 311xxxxx = February 2002 313xxxxx = April 2002 809xxxxx = December 2006	810xxxxx = January 2007 910xxxxx = January 2008 001xxxxx = April 2008 004xxxxx = July 2008	A88xxxx = August 2008 A8Bxxxx = November 2008 A91xxxx = January 2009 A98xxxx = August 2009	A99xxxx = September 2009 B02xxxx = February 2010 C5Axxxx = October 2025 Z9Cxxxx = December 2259

Put the first 3 characters of your serial number into the box below and then click the Submit button.

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 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.
