    I would be interested to know what power FT8 (watts) you working with.

    Anywhere between 50 to 100 watts or what is neeeded to make the qso's work, never over 100 watts though.

    I generally set my radio TX to 40w for the various digital modes, but sometimes I'll boost upwards to 80w or 90w while trying to establish a contact, especially on FT8.

    Seldom bother with FT8 but have never needed more than 10w

    There are so many variables in making a QSO, regardless of mode.

    I usually run 40-50 watts, but have been known to crank it all the way to my max of 100 watts to try to make a QSO. It only makes 3 dB difference, but maybe it will make a difference.

    I'm running a Kenwood TS-590SG, which Kenwood rates at 100 watts RTTY/Digital. If I did run 100 watts continuously, the fans would be on most of the time.

    Interesting question.
    Really depends on the freq too IMO.

    6M lately is open with Es season upon us.
    That said, 6M stations with amplifiers are using them..500W-1000W

    Personally, I think the appeal of digital modes is being able to do a lot with very little power.

    My equipment is:

    - Kenwood TS-2000
    - Output power mostly on all bands 10W (maximum 50W)
    - Antenna DIY Vertical 7M

    This is really nonsensical and I do not approve of it.

    My guess is that those who respond are not seeking approval.

    It's been touched upon but there are variable factors that come into play when deciding on power levels. It's a bit more complicated than the following statement but it about covers it..."the minimum transmitter power necessary to carry out the desired communications."

    The minimum power necessary to make the contact.

    Sometimes it's 5w, sometimes it's 500w.

    Better antennas mean less power needed. My antennas are ok at best, so sometimes less sometimes more, just depends on the band, the competition, the distance and how bad I want to work that station. Sometimes 500w won't get it done so I take a pass as that's all I got. Depends.
