On Friday evening weak Italian signals on the lower FM-band:

For 2-3 minutes I heard stations only from one tower from Salerno-province. That was Perdifumo-Monte Stella-tx-site about 50 km East from Salerno. Stations:
88.0 MHz - Radio Radicale - 16.01-
89.4 MHz - KissKiss - 15.59-
91.2 MHz - Radio Maria - 16.02-
92.8 MHz - m2o (tent.) - 16.02-

Also Radio Company from Benevento on 88.4 MHz was up before these. Seems to be very often audible here. That must be because high tx-site in the mountains.

UNID. Help with this:
89.3 MHz - Radio Erre, UNID QTH. Clear id between the music. 16.07- IDEAS??
