[AMPS] AL-80B Amps

[Steve]

It just boggles my mind the kind of comments we see popping up on the
this reflector. I hope you have an elmer at the radio club and I hope
your elmer has read the ARRL handbook. I think that reading and
understanding the handbook should be mandatory to obtain an amateur
license. The handbook is not perfect but it gives you a good start down
the road.
