What's most important than anything for 100 w. success is the antenna.
Especially on 160.
There are hams around here on 160 with ~100 w. EFJ gear; they do okay
within 150 miles or so but the determining factor is the antenna more
than the power. Unfortunately many hams operate 160 with the idea
that what worked okay on 75 will work (conceptually) on 160. Usually
not true. For most of us some kind of vertical radiator over a good
ground system, and separate rx antennas is the best way to joy on 160.
Things change for a few months later in the evening. When the band
is good and the local time is after around 10 p.m., lower power and a
cloud burner can do okay when not in a deep fade. A lot of that has
to do with lack of QRM and local RFI on the rx end.
