Kenwood Month/Year of Manufacture CalculatorLaurie - 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.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.
Let’s take a closer look:R Resistor - If an R is present, this indicates a resistor type spark plug. Resistor type spark plugs reduce the amount of radio frequency interference (RFI) that can cause ignition misfires and static on the radio.V Shell Design - This refers to the thread size and reach of the spark plug.15 Heat Range - The middle number indicates the heat range of the spark plug, the higher the number the hotter the heat range.YC Firing End Design - The letters after the heat rating indicates a special spark plug construction feature called the firing end design. The letters refer to the center electrode material, projection dimension and ground material.4 Gap Designation - The number after the heat rating indicates the wide gap designation.
Please note, the wide gaps are required to meet federal and California requirements.Find the Design of Your Spark PlugTime to replace your spark plug?
