You're comparing the effect of voltage droop due to a 10W load on a 120V 
(or 240V, for Euros) AC feed with the temperature cycling plus voltage 
droop due to a 1000W+ HVAC unit?

(Was your RG-8 in a separate climate enclosure? Or might you be 
including source/sink changes in your measurement?)

Not only is 10W on a AC power feed pretty insignificant, but unless 
you're receiving a separate circuit from the substation, the building 
(or neighbor's) HVAC cycling will have more effect.

All other comments have been unique to the performance of individual 
devices, not the propagation of PPS through a lab.
