Hi, Your current also seems high. Here is what I get on the 3 bands I use the most:
RX voltage reads 14.1V current 0.85A TX RTTY power set to 100W: 10m 100W 13.7V 14.5A 15m 102W 13.6V 15.5A 20m 105W 13,6V 17.5A Power is measured by LP-100A (factory calibrated) into precision dummy load, voltage and current from the K3 display. The power supply is a 25/30A switcher branded Kenwood KPS-15 although I suspect they did not make it. I have modified it with 4 APP connectors (it's ugly but on the back so I can't see it). The cable to the K3 is a #12 cable, much shorter than the one supplied with the K3 and no fuses or other stuff inline. The APP connectors are soldered. I guess I am fine, no reason to get out that deoxit yet and I never mess with anything that works FB. I suspect the K3 voltmeter reads about 200-300mV high as I read 14.83V out of the supply with a DVM in receive. But the deltas should be accurate.
