[Elecraft] KAT500 actual radiated power during tuning

[E T]

I understand the requirements, and the ICOM IC-7300 puts out 12.5W by default (can be adjusted via service menus).  I'm looking for a definitive answer as to the actual radiated power.  Like I said, the ICOM AH-4 tuner specifies its actual radiated antenna power but the KAT500 does not so that's why I'm asking.

  Thanks and 73,

Erik,

The KAT500 relies on the transceiver power being reduced when tuning.
I am not certain how (or if) that happens with an Icom transceiver, but the KAT500 needs about 20 watts for reliable tuning.
That can happen automatically with the K3/K3S/KPA500 combination, but I don't know what the Icom can do to accommodate that same thing.

I was reading that ICOM's AH-4 tuner itself takes the input power and splits it into an internal dummy load and only radiates something like 300mW out the antenna, is the KAT500 comparable?
