    my 705 puts out about 100 mw power turned off on HF
    The Icom 7300 / 7610 = +1 watt

    The QST Product Review Engineer confirmed with measurement, the factory specification:

    Transmitter Transmitter Dynamic Testing Power output with external 13.8 V dc supply: As specified. 0.1 – 10 W (AM, 0.025 – 2.5 W). With battery: 0.1 – 5 W (AM, 0.025 – 1.25 W)

    You are welcome :)

    But does it spike upon key up? A good way to blow up low drive solid state amps and transverters... Along with PIN diode TR switches.

    something else-

    if the readout only does whole numbers (no decimals) then 0% just means <1%, or
    from 0.000 to 0.999%.

    don't hit me- i bruise easy.

    So now it's not just the 9700 and 7300, but the IC-705 also has the "RF tail" as well? I had such high hopes for this scenario and the 705. The 7610 doesn't have that problem. Why won't Icom fix this?issue?

    KE7TBB askes if it has the spike, not stating that it does, don't jump to conclusions, read, think, write!

    Yep. All Icoms do that. I had an Icom wreck the T/R switch in my amplifier.

    No Icom for me.
