The immediate population is not a problem, but the fact that only 3% of all hams are 20 years of age or less may prove troublesome in the next 20 years of so. I also thought that the age distribution was a pressing problem until I got a copy of the callsign database and actually calculated the numbers. The second issue, a 'aliasing' due the the shift from a 5 year to 10 year license term is also of dubious value. In scanning through the Region 0 data (I don't keep the whole thing on-line), I found that only 97% of the licenses listed in 1988 had been issued or renewed since the change in license terms in 1983. Of the remaining 3%, 2/3 of those were due to expire in the period 1989 - 1992 -- the remaining 1% due to expire in 1988. Anyway, the maximum loss possible due to silent keys, etc is only on the order of 3%. On the other hand, there was a piece that made the rounds on packet, WorldRadio, etc, to the effect that since the number of hams has been growing at a faster rate than the population as a whole there is no problem. That type of analysis is faulty in assuming that society as a whole has remained at the same level of technology. I think that ham radio has definitely declined in importance due to technological advances across the board. rick, N0LOX
