Yes,that was also my own experience and below is Joe*s correspondent comment
from a private email:
"The calculation of S/N in WSPR assumes that the "baseline" noise spectrum
is approximately flat over 2 kHz or so. If you use a much narrower filter
the program's estimate of background noise level may be incorrect, and this
will affect the computer values of S/N.
