=>Then again, if he still has the First Class, it must be a special
=>issuance, since they were done away with in 1982 in favor of the 
=>General Radiotelephone license (the old Second Class). 
=>
=>Whatever that means?  What gaining a commercial license means is that
=>like ham radio, you took the time to study a lot of archane theory,
=>mathematics, rules, and regulations.  You also had to take this test
=>in parts (1, then 2, then 3, then 4) over the course of time, and,
=>on the back of previous licenses, had to have the endoresement of 
=>previous employers as to whether your service was satisfactory or  
not.
=>
=>What the license gave you, in terms of priviledges, was the ability
=>to earn a living by: 1) fixing commercial radio gear (business, cb,
=>etc.) 2) working as a transmitter engineer or chief engineer of a
=>broadcast station (radio or tv), and meant that you at least had
=>something of a professional attitude.  
=>
=>In 1982, to the consternation of many in the industry, the FCC, in
=>its bureaucratic wisdom, combined the 2nd and 1st into the "General"
=>radiotelephone license...the first disappeared, as did the 3rd class.
=>
=>BTW, the licenses were only good for 5 years at a stretch, you had to
=>renew them (with endorsements...) at that time...

Why don't you quit arguing about it al him how to do it.  If you want
to talk about policy then start snother thread.
