[Elecraft] Power output on higher bands

I've noticed some weirdness with transmitting on higher bands on my
elecraft.
Down on 40, and 80, its great. When I transmit the RF meetings goes
almost all the way the up. My w2 responds and shows a good output as well.
However on 20, 15, 17, the RF meter won't even get over 50, it shows
maybe 1 or 2 bars at peak. Now my SWR on 20 is 1.6 so I assume that it
will put out less power but not that big of a loss. I also get a "hi
Curr" on 20 when i hold down the xmit/tune button and transmit that way,
even though I am putting 14.5 v into the k3. It shows 12.6v during
transmit. I do show the meter as showing it drawing almost 23 amp
during transmit on 20, the rest of the bands are about 14amp. Again
these readings are measured when i hold down the XMIT button.
On 10m i get a 1:1 swr match, and it does the same thing, barely no RF
output. So I am not convinced its a SWR match thing.
Have I missed a setting somewhere? Somewhere that I have to turn this
up. I have the PWR turned up to 110.
Anyone have any ideas?
