Sorry if this reply is late, but... :)
For the FM broadcast band in general, DX'ing is limited mainly by
line-of-sight
distance. The higher you can hoist your FM receive antenna, the more
tations
you should be able to get.
And solar activity DOES have some effect on the FM band, although not a whole
lot, unless the ionoshpheric layers are VERY active. Thermal ducting seems
to play a part in it as well.
A good way to judge if FM DX might be possible (not fool-proof): listen for
DX openings in the 6-meter and 2-meter ham radio bands. As both of these
bands fall below and above the FM band, respectively, an opening in both of
these bands COULD indicate a possible DX opening in the FM broadcast band.
But again, a good receiver and a good, tall antenna are important.
