[Elecraft] auto-tuner needs more radio output to tune

[dw]

I had the SGC 100 watt unit for many years feeding a classic 130'
doublet.
Upgraded to the 500 watt model 3 years ago.

Both of them take around 6 seconds to find sweet spot with this antenna
with 15 watts applied from the K2/qrp.
160m to 10m
