Manufacture
Collectors and restorers of ham radio equipment have long had an almost
obsessive interest in their serial numbers. This includes me!
At least Yaesu produced a numbering scheme which could be relatively easily
decoded to allow future owners of the equipment to know fairly accurately
when that equipment was manufactured. This is much more difficult to do
though not impossible if you own equipment made by some of the other manu-
factureres such as Trio/Kenwood, Icom, etc.
Below is a table showing brief details about the radios in my collection
