Agreed.  I used to live in a place where I had difficulty getting
out at all (in the mountains, at -450ft HAAT.  Yes, that's a minus
sign).  Depending on my propagation on 2m/220 and which
multipath/knife-edge diffraction was working for or against me at
that instant, I sometimes needed help to get out to the WIDEn-N
digis.  Ordinarily that's not needed, so use WIDE2-2 for PATH 1.
