[Elecraft] KPA1500 Power Level

[Salvatore ["Ted"] K2QMF]

I have a Yeasu FTdx5000 and an FTdx101MP.
Both are driving Elecraft KPA1500's.
The driver power is reduced to about 35 Watts on both!  I have no over shoot with either rig!
Do not use ALC!!  Lower the drive power.
No issues!  Works Great...

*** Not so bad if you build it INTO the linear - so it would be inside
the
existing relays. But yeah - it's a shame to waste all that power and
heat the linear
more.
