100 watts on 75 meters in the summer works fine, when the QRN level is low.
Often this is in the mornings until the band closes, and in the evenings
until sunset.
CW covers up a lot of power issues.
See the QRP stations.

Matt, while unlimited funds must be nice to have, I'll never know, I know
people who are on 75 meters every single day with 100 watts with no
complaints or problems except a select few who probably would pick on them
no matter what they did. Reminds me of my days on CB radio.
