There are many FM stations around that rebroadcast the signal from their other FM transmitters. However, the signal level is often way too weak as a fully reliable source for the FM relay. During strong propagation openings we have seen (and actually heard) many times the “tropo-hijacking”.
Wiele stacji radiowych UKF-FM dosyła swój program poprzez odbiór z innego nadajnika. Taki sygnał jest często zbyt niski, aby służyć za niezawodne źródło retransmisji. Podczas silnych propagacji widzieliśmy (i słyszeliśmy wiele razy sytuację przejęcia dosyłu przez odległe nadajniki.
