See "Attenuator for transceiver/amplifier interfacing" in the "Articles"
section of my website at www.ad5x.com.
The overshoot problem is a different issue. My IC-706MKII would overshoot to
140 watts on the first dit regardless of output power setting. Duration of the
pulse is a bit less than 2ms. I've been told that the FT-857 overshoots to
around 150 watts, and the TS-2000 to 180 watts but I haven't measured these.
It would be interesting to compile a list of transceivers and their overshoot.
FWIW - my Elecraft K3 has no overshoot.
