Stations Using Orban 9300/9400

A

arg2013

Good afternoon everyone,

I'm looking at the possibility of purchasing an Orban AM processor (either the 9300 or the 9400).

Could anyone give me some specific stations which use each of these processors? I'd like to give a them a listen via their online stream.

I have already found a number of stations that do not use the HD output of the processor but rather stream their 10khz AM signal to the web. The problem is that I don't know what box they are using.

Obviously settings can and will vary between each station. But, as I've read before, Bob Orban has said that the 9400 had some changes made it based upon the NSRC research. IIRC, the research showed that an emphasis in the 3khz area was very beneficial for voice and thus the 9400 made this adaptation. Contrary to this though, I've also read (by a user of both) that he prefers the 9300 for voice and does not like what the 9400 does to voice content.

If anyone could list a station or two that use one or the other, it would be greatly appreciated so that I can at least get a better idea of which I like best.

Thanks!
 
Most AM stations have their 9400 at the transmitter since that's where you get the most benefit from the 9400. Very few stations feed the stream from the transmitter site. Usually the stream is originated at the studio. Usually with a separate processor. Most stations don't feed the stream with an "off the air" monitor since failure of the transmitter or something at the transmitter site would bring down the stream if the over the air signal fails. At least the stream will stay up if the transmitter fails.

I run the 9400 at one station and like it very much. But the stations internet stream originates at the studio. Is this going to be for an AM station or a web stream?

Even if a station was using the 9400 hd side for a stream the setup would vary from the analog AM audio. The only way to hear what the 9400 is doing for an AM station is to actually listen to the AM analog audio through at least two AM radio's.

I would ask who in your local market is using a 9400 and listen to them on a radio. I could list at least two stations using the 9400 but you won't hear it on the web stream.
 
Hi xmtrland,

Yes, I was afraid of that. I decided to do a spectrum analysis of some of the streams and I found that the stream for WBBM-AM (https://www.radio.net/s/wbbmam_) is hard limited to 10khz. Wouldn't this imply that the stream is a direct feed from the processor's AM output?

If so, do you (or anyone else know) if WBBM-AM uses an Orban 9300 or 9400?

Other than that though, everything else I found indeed was an HD stream of some kind.

Thanks.
 
Why do you want to buy an AM processor? Do you do engineering for an AM station. Just because the audio bandwidth is "hard limited" to 10Khz does not mean they are driving the stream with an AM processor. Do you know what the NRSC mask is for AM? It's not hard limited at 10Khz, it rolls off. WBBM is a talk format. Not much need for audio above 10khz so lots of reasons they may limit the audio bandwidth at the studio.

WBBM and WSCR are both owned by Entercom and share a transmitter site. what does WSCR stream sound like. I would listen but it's the weekend and I already have 5 AM 50KW sites to occupy my time, plus an LPFM.
