Hm..
My K3S set to 100W says it is putting out 80W on 6M.
An external power meter also reads ~80W.
I did a gain calibration and there was no change.
But, now you got me thinking.
My 50-Ohm load is +30 years old and I doubt is rated for 50MHz.

Did you check the specs? I don’t think it is supposed to put out full 110
Watts on 10 or 6 meters.

Have you run a Transmitter Gain Calibration from the K3 Utility
Application? If you do, be sure to use a good dummy load connected
direct to the radio with a known good short coax jumper.

Thanks Fred,
Guess I have some issues with my K3s then.
I think it's past warranty at this point.
I'll break out the K3 and try to get it

back for repair and figure how to get WSJT
going with the K3 while 6 is still open.

What is the expected output on 6 meters?
The K3 shows 110W
The P3 watt meter says 73.1W
The LP-100A says 60.1W

only outputs at 7 watts tops.
On all the lower bands it puts out 100
reliably.

Just because the Specification says 20 amps, that is the maximum current

You duplicated the line about the ATU:
ATU* matching range @ 100 W 10:1 (typ) 3:1 Allows monoband antennas to
be used on other bands
It's in the General and Transmitter sections.
Also, I would REALLY like to be able to plug a mouse into the P3, and
click my way around the SVGA screen
Per the manual 50% efficiency. So at 1500 watts output the. input would be abt
3Kw. A 20 amp ckt at 240 V would supply 4.8 Kw. Seems reasonable to have
adequate power for other equipment.

If you can find someone who previously added the KAT100 and KPA100 to an

I based that statement on the 20amp KPA1500 rating shown on page 28 of
their manual. Obviously this is incorrect or it is very inefficient, but
still a station can have multiple heavy duty rotators, computers, multiple

I do not understand the need for three wires plus ground. For a clothes dryer
