Different metering systems will have different attack and release times. Most won’t be able to follow the voice envelope accurately.
It is best to use steady state carrier when measuring power. 500 watts of carrier is the same as 500 watts PEP. If your transceiver drives the amp to 500 watts output with 20 watts, then the correct drive power for SSB is also 20 watts. The K3S feature of PWR PER BAND is excellent in this regard. 73 Bob, K4TAX Sent from my iPhone > On Feb 7, 2020, at 2:24 AM, Craig Buck <[email protected]> wrote: > > A man with two watches never knows what time it is > >> On Fri, Feb 7, 2020, 1:12 AM Paul Braiman via Elecraft < >> [email protected]> wrote: >> >> Putting my brand new KPA-500 through its paces and I’m noticing a >> significant difference between the peak power displayed on the amp, and the >> peak power displayed on a Telepost LP-700 station monitor.
