- HD Radio is a new digital technology
licensed by
ibiquity.com.
HD radio transmission equipment uses space in the sidebands of radio signals
to transmit a digital signal. HD enabled radio receivers can then
receive the high quality digital signal.
Better fidelity, than now available, is most evident with AM HD
radio signals. For example HD radio reception of KEX and Radio Disney KDZR
are in crystal clear stereo. FM stations can broadcast more than one
HD signal on each main frequency.
For a list of radio stations that broadcast an HD signal in
Portland, click the FM/AM radio link below and look for the
