LROP#2 Setup
« on: May 20, 2009, 05:24:20 PM »
Hi everybody,

I'm using a remote location in a rural area, 10 miles away from LROP Bucharest.
The feed is streaming in stereo, using 2 scanners.
Here you have some pictures:

The scanners + PC:


The antenna (i'm using a 13 m mast):


The reception is excellent for both Bucharest Approach and Bucharest Radar. Some improvements have to be done for the LROP TWR.

So long!

Looks great , I have 2 questions
    1- Are you using two sound  card for each Scanner or a multi-channel one ?
    2- Does the software provided allows multiple feed to be streamed from multi-channel sound card ?

Thanks
Mo

Hi

1. I'm using an usual STEREO (bi-channel) sound card. Just like you have one inside your PC/notebook. The way I'm connecting 2 scanners into one sound card is very simple: I'm using a Y cable that puts the #1 scanner on left channel and #2 scanner on the right channel.
2. The software (like other streaming software you may find on Internet) is able to send a STEREO stream. The most Internet radios send their music in STEREO. I just configured this option: "STEREO streaming". The default setting is: "mono" because the most feeds use a single scanner.

Hope I answered to your questions.

I did almost the same thing on two different systems(PC) , one with 4 channels card  splitting the stereo input  to left and right stream programmatically   and streaming each line gsm format . The other one i used a layla card with 8 stereo input that allow to have up to 16 scanner connected to directly . I wrote the software the does the reading from the card splitting the audio buffer from stereo input to mono gsm compressed stream . I was wondering if that software does the same thing or not , like can you specify a mixer from which you can get an input and split plus the streaming ?  .  I will post a pic for my rig later once i have.

Thanks for the insight
Mo

Nice job you've done there. Regarding the Streaming software provided by liveatc: it can use only a soundcard at a time. It is not able to create more than one stereo stream. The other guys that stream more than one feed, they just install the liveatc's software as many times as they need: if they have 3 feeds, they install the software 3 times. I know, it is not a professional way to do like this. I think you should speak to Dave. Maybe he has a special version of streaming software capable to use more than one soundcard at a time, or to use a multichannel soundcard and to generate more than one stream at a time.

Regards.

Regards.

On my single computers that carry multiple streams (BOS, PHL, JFK, SFO, soon EWR) I use a Delta 1010LT sound card, a card with 8 analog inputs.  All those feeds run on Linux, which has ALSA sound card support for the Delta 1010LT sound chip.  I launch a single instance of Darkice (feeding software) for each feed and it is all automated.

Our Windows software (based on Stream Transcoder V3) runs as a Windows service and handles multiple sound cards, but not in a single running instance.  However, this is not as bad as it sounds.  All a feeder needs to do is follow a simple set of instructions (only once for each feed) to add a new feed to the service and then the Windows service handles the rest.  If everything was set up correctly the setup never has to be touched again.  So it is not installing software three times, it is installing a single time and then running a single command for adding each additional feed.  As long as Windows "sees" the additional sound card, the LiveATC software can see it as well.

Hope this helps clear things up.

Dave

:)) Not yet. That flag is from my cousin. He's the one who lives in Canada. A coincidence is that, here in Romania, I'm working in a canadian company.

I see you are using two scanners... because sometimes scanner equipment is scarce (or expensive) wouldn´t be cheaper to get a cheap mixer to mix both channels and input the mixed signal to the computer, so you can use the scanner for something else? just a question...   :?

Sorry for my late answer.... According to the feed's description you may see that there are many frequencies to scan. If I use a single scanner for all those channels, nobody would understand anything from those mixed conversations. So there was a need to organize the frequencies. Thus, I separated them in Approach + Tower (for channel 1) and ACC for channel 2. There is a scanner per channel. Every scanner has his own frequency list configured. If I would configure all the frequencies on a single scanner... that will bring me to the situation I've described above.

Cheers!
