IBOC killed the DX star!

I remember being at Dayton Hamvention a number of years ago where a speaker solemnly predicted the end of TV DXing as TV moved to digital. Those digital signals just wouldn't be detectable by tropo and e-skip. Wrong! There are confirmed reports of digital TV DX by e-Skip (see www.dxfm.com). It may be we're opening up a whole new world of DXing, even though analog reception could be very difficult.

We really don't know what IBOC's DXing potential is, since only a small percentage of stations are using it and even fewer people have tried to specifically DX digital stations with HD radio equipment. While it affects the reception of weak stations immediately adjacent to closer stronger stations, strong tropo and E-skip conditions that cause analog stations to come in like locals may not be any different than they are now.

I'm still thankful it hasn't come to central Alabama yet, though.

Yes, but the problem with skip on the AM band is just that: it's the AM band, not VHF or UHF. With the nature of the AM band being what it is (crowded, 10 kHz spacing, vastly overpopulated), IB(A)C (and the fact that it's not on-channel as it claims to be) is going to make DX'ing extremely difficult due to the fact that the system is not set up to detect and separate the digital streams of co-channel stations. The way the AM band is set up, no matter how much you change the technology, it most likely won't be possible to do that in the forseeable future.

VHF and UHF TV, on the other hand, is set up in a way that's very condusive to DX'ing, digital or analogue. Instead of using up sidebands for a digital stream, digital stations are on an entirely different frequency than their analogue sister stations, thus taking up the same amount of bandwidth on a different channel. Digital TV also carries with it's signal a flag that denotes what station you're recieving, making it possible to distinguish between stations' streams. All of this combined allows for the same tropo and e-skip effects in the digital realm without having stations mesh together.

I do agree that DX'ing AM radio in the digital realm would probably be a new excitement. Trying to pull in that long-distance digital signal from halfway across the country would become something us DX'ers just drool over :) However, the fact is, that's not the way AM radio was meant to work in the first place. Regional clear channels were set up to be such for a reason... a reason that could still be argued for quite easily today. The idea of trashing any frequency, let alone those set aside for regional use, with IB(A)C streams makes me sick. The ease of receiving long-distance stations wouldn't be easy at all. That's something that, for both entertainment and safety reasons, worries me.<P ID="signature">______________

A quick addition to my comments that I forgot to mention in my post above: just as IB(A)C is not designed to detect and separate different streams from co-channel stations, it is not designed to detect and separate different streams from adjacent channel stations either, making things even more difficult.<P ID="signature">______________
