Right. I guess I should have said this was assuming people are using handheld antennas like the Arrow II.
Some time ago we talked about someone who had so much gain even setting their radio to the lowest power setting of 5 watts was too much for AO-7. It was recommended that they add attenuation in line or aim the antennas slightly off from the satellite.

At the same time, I know of a sat op who only had 5 watts and I heard this sat op not wait for a rover and call them immediately after someone else called the rover. I speculate that this sat op with only 5 watts started doing this because they could not get through at all in other way due to many people using over 5 watts.
Also remember that it isn't the wattage of your transmitter; You can have a bunch of antenna gain, concentrating all that power from a sphere into more of a teardrop going to the satellite, and overpower someone using 100W and a rubber ducky (assuming it didn't melt).

Unfortunately, FM birds don't let you gauge how much power you're getting into their receiver by comparing your receive signal to the beacon.
