[Elecraft] KXPA100 + KX3 High SWR at Power

[Paul Siken]

I've set up an 80m dipole along the top of the block fence in the backyard
at a height of about six feet.. The KXPA ATU is able to get a 1:3 SWR when
it tunes, but when I attempt to run CW at 50 watts the SWR is off the scale
(high). I have to reduce output power to 10 watts to bring the SWR down to
1:3. If I bypass the KXPA, the KX3 ATU is able to achieve the same SWR and
maintain it at 15 watts. Any suggestions?

Thanks,

Paul, KI7LW
