Re: Signal generator terminology query
You don't really need a signal generator of any type to work on old radios, though a basic one does make realignment easier. For FM work you ideally need a wobbulator (sweep generator) and a scope, though again you can usually get by without.
Many forum members here have a *lot* of high end workshop kit, but this has usually been acquired over many years and often 'liberated' from day jobs in electronics.
