[Kenwood] TS-930 serial numbers

[Dan Violette]

The part date codes confuse me, but:

Every Kenwood I have seen subtracts 2 from the first number for year and then next two month.

So yours, January 1983.  The rest being sequential that month.

 Has anybody ever nailed down how to determine the production date of a
'930?
 
There is a sticker on each of the fans indicating manufacture on 29 May
1984. The highest production date that I have managed to find on any of the
ICs is 8421 (21st week of 1984, also in May of that year). 

My unit is s/n 501xxxx. This suggests that the date of production was
probably the first week of 1985. Makes sense. It couldn't have been
assembled before the parts were produced!

Ken, VE3FIT
