[Boatanchors] AM Amplifier

[Jim Wiley]

I have been watching this thread  for a bit, and one thing is becoming 
clear:

All too many users are attempting to operate AM without proper 
monitoring equipment.  There is absolutely no substitute  for a monitor 
scope that samples the outgoing RF.   There are many instruments that 
can do the job.  The Heathkit monitor scopes will do this.  There are 
many other examples, too many to list here.

Find a ARRL or " Radio handbook" from the late 50's or mid 60's and look 
up "modulation"  and you will see how a properly modulated AM rig's RF 
envelope should look.  You will see that the resting (unmodulated) 
carrier level is about 25 percent of the peak power.  For example, when 
working with a nominal 100 watt output rig, adjust the rig for about 25 
watts with no modulation, which will give 100 watts on voice peaks. 
Anything more will give rise to distorted audio and a lousy signal.
