>Setting a power control calibrated for CW and expecting that level to be accurate for PSK31 or any other arbitrary digital modulation is complete folly and utter hubris.
I also read another post that the K3 watt meter is an average power responding device and there in lies a problem of setting power for an arbitrary waveform that will not create IM products. In the old days we could use a monitor scope to make sure we weren't clipping. An interesting thought about a future K3 band scope is to provide a station monitor mode... I also wonder why the internal K3 wattmeter does not have a peak detecting mode and set the PEP power to the requested level. That doesn't take care of directional coupler errors but I suspect it would drop the complaint level down 6 dB. K3 output power vs. requested power has been a continuous theme on the reflector. What is wrong about setting and displaying peak envelope power or at least have the ability to switch to a peak detecting mode? It seems to me that if we are worried about IM products when approaching PA clipping levels that PEP is what we should be monitoring for any transmitted waveform.
