100 watts on FT-8, seriously?? Most hams I know run anything from QRP to 35 watts. 100 watts is waaaay overkill. FT-8 is a weak signal mode, which while it does not mean QRP mode, it does mean that wsjt can copy signals when you see nothing at all on the waterfall display. It can pull signals down at the noise floor that you can't even hear much less see on the display so 100 watts is a ridiculous amount of power read the manual. Ron - KJ5XX |

True up to a point but if you are +6 and the other is - 20, who do you think gets called first? Does this mean I cannot use by 4 element Yagi at 70 feet? Oh well, I do not have that 😊

You might want to watch this video: https://youtu.be/gtY2d4eSmm8. They make it pretty clear about power settings for this mode. In a nutshell, if the station you are calling doesn't answer, increase power. 73,Mike, AE8USent from my T-Mobile 5G Device

Antenna gain is also a factor. 10 Watts to a simple dipole or vertical is different than 10 Watts to an aluminum stack on an aviation hazard tower. And then there is also the noise floor at the other end...

Yes, SERIOUSLY. It's a weak-signal mode, not necessarily a QRP mode.

EME is weak signal, but how much power do they use there? Vy 7 3 Earl / KD5XB DM84 On Sat, Dec 3, 2022 at 3:55 PM Ron <KJ5XX@...> wrote:

As much as they are allowed and very high gain antennas too. LARGE ERP. 😊
