This is what is know as "blanketing interference" and there
are rules against it (or were when I was actively working
as a broadcast chief engineer). Stations are (were?) required
to minimize blanketing interference and take steps to remedy
the problem on a case by case basis.
I would look up the applicable rules (in CFR47) and then
contact the station directly with a written complaint
(copy to the FCC Field Operations Bureau ... whatever they're
called today).

Since Pete mentioned problems with TV channel 6 reception,
trapping is essentially impossible ... 87.9 is actually
INSIDE channel 6 (82-88 MHz). I am sure that Pete will
NEVER see channel 6 again other than when the FM station
is off air.
