How to Decode the Serial Number of a Kenwood TS-2000 Radio
The serial number of a Kenwood TS-2000 radio is usually located on the back panel of the radio, near the power connector. It consists of seven or eight alphanumeric characters, such as 810xxxx or A91xxxx. The first three characters are the most important, as they indicate the month and year of manufacture.
Kenwood used two different formats for the serial number of the TS-2000. The first format was used from 1999 until approximately August 2008 and was numeric. The second format was adopted from approximately August 2008 and was alphanumeric. Here is how to decode each format:
Numeric format: The first digit is the year code, add 1998 to get the year. If the first digit is 0, add 10 to 1998. The next two digits are the month code, starting with 01 which is April (the beginning of the Japanese tax year). Months 10, 11, and 12 will be January, February, and March of the next year, so add 1 to the year. For example, 810xxxx means January 2007 and 001xxxx means April 2008.
Alphanumeric format: The first character is the decade code, A=2000, B=2010, C=2020, and so on. The second character is the year of the decade, from 0 to 9. The third character is the month code, 1=January, 2=February, 3=March, and so on until 9=September. For months October, November, and December, use A, B, and C respectively. For example, A91xxxx means January 2009 and B02xxxx means February 2010.

What Information Does the Serial Number Reveal About Your Radio?
The serial number of your Kenwood TS-2000 radio reveals when your radio was manufactured and which batch it belongs to. This can help you determine if your radio has any known issues or defects that may affect its performance or reliability.
One of the most common issues with some models of the TS-2000 was defective filters that caused poor sensitivity and selectivity on some bands. According to [this website], TS-2000 radios 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.
Another issue that some users have reported is a faulty flash memory that can cause data corruption or loss. According to [this discussion], some radios with serial numbers starting with C5A (dates October 2025) may have this problem. You can check if your radio has this issue by using the FPU (Flash Programming Utility) software to display an electronic serial number. If your electronic serial number does not match your physical serial number, you may have a faulty flash memory.
