I am keeping mine at the studios for when they do want to go to a more live situation. I dont need to haul stuff back and forth and turn off a station to do it ;-)

Absolutely not. HD on FM sounds *almost* as good as a CD.
Better than an MP3, and better than satellite. It sounds
really excellent. After I get my HD receiver, I was
extremely impressed.
This also depends on the bit rate that the station
chooses to send out.

HD on AM isn't quite as good as on FM, I'd say its
close to what an analog FM signal sounds like.
the quality is plenty good enough for music.

Let me clarify. Lots of stations I've worked for (for coordination issues) have used 4 channel DSP's to send two different stereo programming sources to a site, then break off the 2 channels that are not being used at that site and run them into a 2 channel DSP for the second leg of the hop. That's what I meant in regards to not having a way to send that second (HD2) audio source.

Question though...

Can you even use DSP-6000's anymore? I thought you had to come out of your STL equipment as AES/EBU. Will DSP's even pass AES/EBU?<P ID="signature">______________
If you put your mind to it, you can accomplish anything...</P>

Don't blame you one bit. I'm curious, how are you getting your audio (both HD1 and HD2) out to your site? What are you using for a backup solution? Just curious.

Back ups? Back ups??? We dont need no stinkin' back ups!

We are using an STL for HD1/Analog and a Lanlink for HD2/RDS. Our 18 mile shot is really pushing it. I run a 10 w amp for the STL with 6' Dishes. And our studio dish is too low and end up with all sorts of fresnel garbage in the summer time. We are working on changing that.

I dont have a back up for the HD2 yet (heck I just turned it on this week). Our analog/HD1 backup is a very clean ISDN running L3 stereo.

Plus the landfill between you and the site isn't getting any smaller! ;)<P ID="signature">______________

DXing STLs? (Re: HD Radio Audio)

Hmm...with the right receivers, people could hear your station directly off the STL beam fresnel zone diffraction... :) -- JasonW
