HD digital radio-Jamms your neighbors-FOR BROADCAST ENGINEERS
It is a matter of record that 2nd adjacent interference to analog was observed in both the AM and FM IBOC systems, under laboratory conditions with pristine signals.
We've been through this one before, but I guess I'll have to say it again.
It is not necessary to postulate Tx problems in order to have 2nd adjacent issues. It is a matter of record that 2nd adjacent interference to analog was observed in both the AM and FM IBOC systems, under laboratory conditions with pristine signals. Obviously IMD from the transmitter canmake matters worse, but problems may exist even when the IMD is insignificant.
