[Elecraft] K2/100 and QRP Mod.

[Gerald Pfaff]

> The threshold is 11 watt...

K2 #1185 has the modification from page 101 of the K2 Manual Rev B for =
improved transmitter efficiency at low power levels. It is CW only and I =
like the "safety margin" to the rated output.

When the KPA100 takes over at 11 watt of drive from the K2 PA there will be =
a gap from about 7 to 11 watts where neither the K2 PA nor the KPA100 will =
give output. (I can easily live with this.)
What is the maximum output if I do not rewind T4?
Will I have a QRP rig  (0,1 to 7 watts) when I power the K2 and a QRO rig =
(11 to about 70 watts) when power is applied to the KPA100?
=20
One last question remains: How many toroids are there in the KPA100?
