With the thought in mind about novices recrystalling cb's as a phone rig. It took alot of research on my part to learn how to do that. I finally figured that out. Not because i was just curious, but 5 of my neighbors gave me cb's because they no longer wanted them and couldnt understand that i was not a cb operator.  I could find few hams interested in helping me develop the skills i needed. I hope to find the right crystals now to convert them and give them to new hams as the cycle revs up again.

Another  step in that direction occurred years ago with "Novice 
Enhancement", when the FCC granted Novices and Technicians access to 10m 
phone, but restricted it to SSB.  A Novice (now Technicians) cannot legally 
build up a simple, low power AM transmitter and use it to get on the air on 
phone for the first time. He can't even re-crystal an old crystal-controlled 
CB rig, or reset the synthesiser in a more modern one. It is highly unlikely 
that a new Novice or Tech would undertake the project of building a homebrew 
SSB transmitter.  Instead, he must buy a plastic radio, setting him 
immediately on the path of appliance operation.

I recall my very first attempt at phone, a "cathode modulator" that used a 
6Y6 tube and carbon mic, that plugged into the key jack of my single 807 CW 
transmitter.  I didn't really know much about modulation and how to properly 
tune and load the thing, so my modulation was probably no more than about 
20%, but I was able to get on the air and make my voice heard.  I must have 
had a half dozen contacts with that rig before I built up a simple plate 
modulator with a pair of 1625s.

In Canada and UK they now have an entry level class called a "Foundation" 
licence. Licensees in that class are not even allowed to build or modify any 
kind of a transmitter.  They must start off using plastic appliances from 
the outset. There has been a lot of clamour in recent years, since the 
elimination of the old Novice class,  to re-establish some kind of entry 
level licence other than the Technician in the US.  I am afraid that if such 
a ticket were ever created, it  also contain a similar  restriction against 
homebrewing.

Things improved slightly with the phone band expansion and elimination of 
the old Novice sub-bands. Technicians can now operate CW (restricted to the 
former Novice power level, IIRC) in the General class CW bands. So 
conceivably, a new Tech could start out on HF with a homebrew CW rig even 
though the code test was not part of his exam.  This may encourage a few 
Techs or prospective Techs to learn CW, since that is one way they can 
operate in the lower HF bands before taking the General class exam. But last 
time I  looked over the Technician question pool, there weren't a lot of 
questions about that type of operation.  The exam was oriented  more towards 
VHF/UHF and repeaters.
