O.K. I have done a test on my power supply a Mega-Watt switching 33amp for use on my base station to power alone a RM Italy KL-503 running behind a Cobra 148GTL Malaysia "Brand new old stock a real find" Anyway I am getting readings of nearly 500 watts with forward swing on several different meters all reading the same I know something doesn't sound right so I wanted to see if I could get even more watts possibly my power supply was inadequate so I hooked up my linear alone to a portable jump start box and then checked my watt meter with the KL-503 on max setting 225 watt max reading now OK so maybe the jump box might be weak it is a couple of years old so I have a fairly new truck battery being stored right now fully charged a top of the line battery with 1000 cca about the max in batteries so I again hook up the KL-503 alone to the battery and I get the same exact watt reading again 225 watts on max setting. Now I tend to believe the 225 watt reading but how is this possible that I get such a higher watt meter reading from my power supply I don't believe I am getting more power but why do the meters show this 500 watt reading when linear is powered by the power supply?
