I would have thought easy to measure the load/no load voltages....
Is that also measured 14.0-14.2V at the equipment DC input or is that to assume no or some voltage drop on feeder cables from the PSU etc? Quick calculation for 22A of feeder say a 1m twin 6mm2 cable will show c 0.23V drop over a meter (smaller cable bigger voltage drop and vica versa) so if 14.2V at PSU and 22A (100W) 'should' be about 14V at kit if using large enough feeder cable ... just asking.
Also as qrp bit of an oxymoron talking about 30A psu, unless it is for the lighting and AC maybe hihi.

All Elecraft 100-W amplifiers are designed for optimal performance at about 14 V (as measured at the DC jack on key-down). This includes the K3's and K2's internal 100-W amps as well as the KXPA100. They will certainly run from lower voltages -- down to about 10.5 to 11 V -- but for home use, we recommend setting the DC supply to 14.0-14.2 V. They'll run from as high as 15 V, though again, around 14 V optimizes power output, IMD levels, and efficiency. >> >>73, >>Wayne >>N6KR
