[Elecraft] [KXPA100] minimum drive?

[Dick Dievendorff]

When you turn PA.MODE ON, we use the KX3 alone for power levels up to 10 or
12 watts, and then enable amplification above 10 watts. The KX3's power knob
ranges from 0 to around 100 watts with PA MODE ON.

However you can turn KX3 PA MODE OFF and set the KX3 output power for the
desired KXPA100 output.   You can do this with any QRP transceiver.

You may find the drive adjustment a little touchy for very low amplified
output levels.

What is the lowest drive for the KXPA100 (not to produce 100W, but for lower
output), and is it possible to get the amp to run, when connected to a KX3,
with a low output power of, say, 10 watts?  I'm wondering about a situation
where you'd like to have the KX3 putting out a watt or less to keep its
temperature more stable and the drift down, and still have the KXPA100
in-line and producing perhaps 10-20 watts?  Is that possible?

Thanks and 73,

Eric WD6DBM
