[TenTec] Orion AM ALC

Jerry is right about power limits.  Under the  present rule  limiting PEP 
output, there is no point in running more than 100% positive  modulation, or 
much more than that anyway.  As for the 1950s "ultra  modulation" system, as 
I mentioned earlier we had one at W1MX and to my  knowledge we never got a 
splatter complaint.  I can't tell you, however,  how much over 100% we 
actually went -- probably not too much over, due to the  tubes (pair of 304THs 
modulating a pair of 304TLs), transformers and power  supply.  I just don't 
remember, because I operated mainly CW then as I do  now.  I used AM only to 
keep skeds.
