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

[Julie Royster]

The LDG tech support folks say that a 5-watt KX3 output is not enough to
trigger tuning by their product.
We will eventually have the Elecraft tuner for KX3 when it ships, but for
now what selection of modes & power etc on KX3 would give me the
highest-wattage signal for the autotuner?  If I understand it correctly, PSK
and CW are limited to 5 watts by the KX3, right?  
THANKS in advance!
