>=3B The first 3 nig= hts were opera but last night was carrier until

>=3B Yes it is= possible for winter day maximum to exceed that

>=3B Propagation is complicated = at short range because there are
>=3B many modes (or combinations of r= ays with different number
>=3B of hops if you visualise things that wa= y) contributing to the
>=3B total signal. When calculating signals by= ray tracing it is
>=3B usually necessary to include paths with up to = 12 or 15 hops
>=3B at least=2C in order to get a model that resembles = a real diurnal.
