Hi and thanks for the answers so far,

To give a bit more detail...

I'm not using any antenna tuner in my K2, it's the basic K2 with SSB module
and battery pack, but for the power out measurements I'm using a DC PSU.
I've set the K2 to CW and keyed the microphone, with the Power turned full
clockwise...

The output reading is on the YS-60 is using the 20 watt scale. The dummy
load is true 50 Ohms, and this is what I get...

Band   Mhz            K2 LCD       YS-60
80m    3.500          15.2                18
40m    7.050          14.8                16.5
20m    14.200        14.8                14.5
17m    18.150        14.8                14.5
15m    21.200        14.8                12
10m    28.500        14.8                8

It seems like a lot of disparity on 10m, but I would have thought that even
if the winding on the 10m toroid were not perfectly spaced, it shoudn't be
that far off?
