Studio-transmitter links are typically placed below the CCIR band – somewhere between 50 and 87 MHz. They often carry a full MPX signal with stereo and RDS, so these signals are quite easy to identify. Italy has a very high amount of such transmitters. STLs usually are low power but they almost always don’t have a co-channel or adjacent interference during reception – this band is empty here. Since I have modded my XDR-F1HD I can receive also everything above ~60 MHz during Sporadic-E propagations.
