[Yaesu] Serial Number and year of Manufacture.

[Graham Shortreed]

I know that this has been discussed before, but I want to confirm my suspicion.  I know that the 1st number in the serial number is the year of manufacture (correct?).  What I need to know is what years the rig was made.  I'm going to be looking for a 990, and want to get the latest production and make sure that I get ver 1.3 ROM.

73 to all and thanks for your input.
