iBiquity has long claimed that HD radio eliminates the static and interference typically associated with analog AM reception. Here are some RFI produced by my pump and belies its statement - causes the receiver to fall static analog, and then it takes several seconds to recover the digital signal. The receiver is an HD Radio tuner Auvi Radio Shack. FM is fine, but on AM it performs very poor, even in analog signals. WOR is the only "HD Radio (IBOC DAB) signalI can reliably get a digital on the AM band. Flakey WFAN is the best, and all other digital signals show a blink "HD" symbol at the receiver, but can not decode digital audio. Furthermore, the digital audio compression artifacts to produce a very grainy, metallic sound - very hard and unpleasant to hear. WABC analog sounds much better, once the recipient opens gradually to its maximum analog AM audio bandwidth of 8 kHz. The last time I tried an HDThe radio receiver in 2007 and nothing has improved since. Even in the best of FM signals, digital audio is still hard and metallic, digital reception is still very flaky, and radio stations still have problems synchonizing your analog and digital audio files. Thus, despite all the hype, "HD Radio" is simply not worth the money, and analog AM / FM radio still works and sounds better!
