This is the same drum Wayne Green W2NSD/1 used to beat. It's not QUITE as loud as it seems.
Some years ago I had occasion to deal with a group of Japanese engineers visiting our company. I got to talking to one of them. Found our he was a ham. That's cool except... he had not been on the air since he was in Grade School! And he may have been typical:
From "Japanese Radio Statistics" at http://www.speroni.com/MPT/Information.html
"The Japanese MPT issues two separate licenses to Amateurs - an Operator License, and a Station License. There are four Operator Classes: 1st, 2nd, 3rd, and 4th which are roughly equivalent to the U.S. Extra, General, Tech Plus, and Technician licenses. Operator permits are for life, and the MPT has no way of tracking status of licensees, so the data published really states the cumulative total of Operator licenses that have ever been issued. As a result there are approximately four times as many amateurs with operating licenses in Japan as in the U.S., with a population less than half."
How may inactive hams do WE have with "only" a ten year ticket? Lots. Imagine a lifetime one.
