[Amps] Questions on Alpha 8410

Correct. The overshoot, generates a DC voltage which holds the drive 
down for the next bit of the rf envelope. The overshoot has already 
passed out of the radio and through the amp.

However, if you have a permanent, constant voltage applied to the ALC 
line of the transceiver, you can set it up so that you will not get 
overshoot or overdrive.

Learned that from VE7RF.
