Looking at my IBP beacon monitor pages over the last couple of days I have noticed an odd thing. I am not receiving the Madeira beacon CS3B on 17m at all.
Extract from G4ILO beacon observations
Either my multiband dipole has a very sharp null in that direction (which I think is unlikely as an indoor antenna probably receives enough reflections not to have any sharp nulls) or the beacon isn't transmitting any signal on that frequency.
A quick check around other beacon monitor pages and I can't see any spots of CS3B on 17m at all. Should I tell someone?
