[AMPS] Re: [CW] calling cq / fone ops

[Kenneth D. Grimm]

So long as you are mindful of the duty cycle, there is no reason at all
not to run an AM signal through your linear amplifier.  I did it for
years with a pair of 4-400As being driven by a Viking Ranger.  With a
lot of air cooling them, they made a fairly big noise on the band.  If
you run RTTY through your amp and it hasn't melted, then AM should be no
problem.  Be prepared, however, for the AMers to look down their noses
at a low level modulated rig.  You really should dig out that old iron
and build up something state-of-the-art...like a couple of 813s
modulated by a pair of 811As.  :*)

p.s.  Don't forget the 866s or 872s.  Watching them was half the fun!
