My serial number tag just lays on the shelf below the radio
It's a lower serial number than yours, so no help there.
Perhaps we can estimate how many total ANAN owners there are. There are not quite 1700 members of the Yahoo Group. Figure only two thirds of them actually have radios. And there are 530 members here, but most of those are also members of the Yahoo Group.
Conservatively, let's just guess that there are twice as many ANAN owners as there probably are ANAN-radio-owning members of they Yahoo Group. So that's maybe 2400 ANAN radios in total circulation. Not a huge number. It's anyone's guess how many of those are 8000's. I suspect it's less than 500, maybe a lot less.
