Particularly a TS-790A. I have serial number #0100410. Can anyone help with info on this? I've been looking high &amp; low but nothing on the NET. Thanks.

Awhile back on Eham, I asked a similar question. To which I received:
&quot;Most Kenwood serial numbers work this way. The first digit of the serial number is 2+ last digit of the year of mfr. The next two digit are the month, with 01 representing April (although there is some debate about this). The remaining numbers are sequential.&quot;
Does this applies to the TS-790A? I can't confirm. If it does, first determine what block of years the 790 was made, if any rig is made more than 10 years, The first # would seem to repeat? -- So, you could have two answers. Anyway, according to Rigpix, for the 790, the first year it was made was 1988 (which seems to fit your rig)--example; 2+8 (from 1988) = &quot;0&quot;, your first digit. Next &quot;10&quot;, your next two digits, would be January (starting from 01 April). Is it really Jan. 1988 that your rig was made? I don't recall the 790 being around in 1998, so it might be a good guess. Thanks to W2AEW for the original Eham post, I hope it was O.K. to repeat. Also, I hope this helps you out. 73, Doug.

Just wanted to add one small clarification, to help. 2+8 (from 1988) does not = 10 or 1. This would be 1989. Also, remember that the full serial number is definetly not sequential. I see this confusion all the time with Kenwood stuff on Ebay. A so called 5 million #, although promoted to be, is not better than a 0 #. For example, it may be 1983 (5) compared to 1988 (0). A FIVE year difference. The 5 # though will sell at a much higher premium, GO FIGURE! 73, Doug

1st digit minus 2 is the year.

So,

Kenwood Serial number

XYYZZZZ

Year = X-2 (last digit of year)
month = yy
order on line = zzzz

I never encountered the second digit 01 being April until I saw it here.

You can always post on Kenwood@mailman.qth.net to verify and have them go ballistic because of the question being asked 100 times so far this year. HAR!
