Hmm... looks like a HD radio won't help me get KDIS...
their daytime analog signal is completely clobbered (with most normal setups) by a local on 1130, and there's also one on 1090. Best chance to hear them, though, is right before sunset, when I can often hear their IBOC hash on 1090 and to a lesser extent on 1130.
What I'd like HD radio to be able to do is...
you have high end AM analog tuner (super sensitive and selective), 10 foot loop antenna, full wavelength beverage antenna tuned to the station you're trying to receive, and your signal reception is ZERO, not counting the fact that you have a local adjacent < 1/4 mile away.
From the SAME location, with an HD walkman that's about the same cost as an average cassette / radio walkman is today, you get a solid clear signal on that non-existant station.
2 - you're tuned to a graveyard channel. Want to listen to a station in New Mexico, but a local in San Diego is also on the same channel, so.. there needs to be some way to select co-channels.
3 - let's say for example 770 KKOB is broadcasting HD only, while 770 WABC is analog. You have an analog radio at KKOB's transmitter site, with a large loop antenna. You hear WABC loud and clear without any trace of KKOB.
