Generally true, but this past summer, in July, I was talking all over
the East/Central US on 2m and 6m, via some kind of bizarre propagation.
SSB will get you more bang for the buck than FM will, every time. And
CW will do even better.

If I remember right, if you have 100W FM, you will do as well as 25W
SSB, which will do as well as 4W CW.

Yep --- some of the rare propagation modes mentioned by the original
poster -- Yours was probably sporadic E
But as the original poster said -- it can be months before it may occur.

Here is the drill for sporadic propagation seasons.

Studies over many years for sporadic E propagation have shown peak activity
in the summer months with another smaller peak in the winter. Nearly 80% of
the yearly totals of Es propagation take place from May through August, with
maximums occurring in June or July with June being the more common. Some Es
can take place in late April and early September.
A lower but significant occurrence takes place in the month of December.
March usually exhibits a definite minimum of Es. However, Es can occur on
ANY DAY OF THE YEAR and these are termed off-peak openings.

However sporadic E propagation can produce very strong signals on the first
hop and I have worked many 6M stations several hundred miles away on FM,
when asked they sed they only had FM capability. So when you can work
sporadic E with SSB -- also try the FM segment -- I have worked some rare
states this way. Ditto of course with CW usually down band from the SSB
segment.

When multi-hop Sporadic E occurs -- one can work all over the USA

But SSB will do better and CW will get thru when the others failed. Your
power figures are about right.

Worked 48 of the 50 States on 6M -- mostly SSB, Some FM and Some CW

With 100w and an old 19 element beam on the roof of the house (up 35 ft), I
can work 150 mile circle pretty regularly with ssb and cw.

I had lots of fun with 10 watts and a homebrew 7 element yagi for years though.

Sure beats repeaters IMHO!
