in standard configuration you can only use one transverter at a time, no

Dear Jack,
I´ve been using my K2 and K3 with the IC2KL for several years and I haven´t
used ALC, although this is not recommended by the members of the Yahoo IC2KL
group.They say using ALC with this amplifier is a must.
The internal protection of my 2KL works very well here.

E=IR in a circuit. To determine volt drop in a circuit it is a simple
circuit resistance multiplied by the current. Simple ohms law and nothing
squared.
Bob refers to IR loss in the circuit feeding the amp as per above line and
not meter efficiency equations.
Circuit; 1 ohm x 20 amp = 20v volt
The thing that matters is the voltage reduction under load.
IR is correct for the voltage reduction.
I squared R would represent the power reduction from the power panel
to the shack.
