Your favorite HD radio station?

With my favorite HD station, you can physically connect a wavelength-long beverage receive antenna for a field intensity meter directly to the output of the transmitter (or would losses along the wire dictate using a shorter antenna at such a close distance?), tune the FIM to the HD station's carrier frequency (not its analog parent), and it wouldn't even lift the needle off the 0.01 µV/m bottom-end peg for AM or the 0.1 nV/m peg for FM. In fact, the field may well be so low that you risk breaking the needle, and that's assuming the FIM and antenna is sensitive enough to pick up 50kW AM stations below 900 kHz 1000 miles away during the day. (I know of someone who used to post here who, from near Lubbock, TX, using a 4-foot box loop and GE SuperRadio, was able to log Denver, Atlanta and Chicago around midday.)
BTW I could be wrong, but I picked ultra-low fields for the AM and FM signals to try to ensure that even in the quietest situation (for RF noise) possible (no man-made or lightning noise generated within 12,500 miles for example, and if there's any spot on earth's surface I left out that could have room for a noise source, it'd be so weak that you couldn't detect it even at the source with a direct physical antenna connection to it) and the absolute best receive equipment possible, there would be absolutely NO chance of even detecting a trace of a QRSS CW carrier, let alone being able to identify the nature of the transmission (never mind identifying the actual signal). Did I need to pick lower field intensities by any chance?

Actually, I'm not against digital if properly implemented. A few things I expect from digital:
Better spectral efficiency (transmit same audio response without compression artifacts in a fraction of the bandwidth - for example maybe 160 kbps in a 10 kHz wide channel; with sharp enough brick-wall bandpass filters at the transmitter to enable using a digital receiver with the selectivity of a crystal set (I'm thinking one that if the signal is audible at all, it's heard across the entire band from 540 to 1700) to hear weak adjacents at the transmitter site)
More robust weak-signal performance (clearly decodes even when a 20dB stronger co-channel analog would be so faint that you have to use a BFO just to detect their carrier)
Not sure exactly how to categorize this, but an example would be the ability to choose one station on the graveyard channels to listen to. If it puts a signal in your area, you should be able to hear it on digital even if you have a local on the same channel.
Doesn't interfere with non-digital receivers, even when attempting to receive DX on the same frequency at the digital station's transmitter site.
There's probably a few more if I thought about it long enough, but that's probably enough to make it hopefully clear that I despise the current incarnation of digital.

Right now, a Digital Pipe Dream. But dreaming is good: someone will invent what we all desire someday, robust reception of Analog and Digital signals coexisting in the same spectrum. Wish I could develop the aforementioned specs, I'd make plenty of $$$$!!!!
My favorites in DFW are:
- KZPS 92.5 HD2 - The Music Summit (Adult Alternative)
- KJKK 100.3 HD2 - The Sound of The Strip (Las Vegas-related Jazz Standards)
- KJKK 100.3 HD3 - The Indie-Verse (Indie/Alternative) [Audio's kinda cruddy, but great playlist]
- KDGE 102.1 HD2 - The Cutting Edge (Alternative/Local)
- KMVK 107.5 HD2 - The Oasis (Smooth Jazz)
One favorite I used to listen to was KHKS 106.1 HD2 "Wild" (Rhythmic Contemporary) until it was replaced by "Pride Radio" earlier this year. Rest In Peace "Wild DFW".

KRTH-HD2. Johnny Mann singers jingles and as much of the orignal K-Earth energy as can be mustered from an automated jukebox. Selfishly speaking....from me, the ad guy...it'll hopefully be a while before CBS figures out how to sell this and load it up with 18,21, or however many minutes of commercials per hour! ;D
