RadioFeed

TSYS metadata tag would be nice.

Oh, well, I suppose you could get the time from a number of sources, I was thinking GPS would be the most precise.

But maybe I'm not explaining it well anyway. Here's a simple example - you want wide area coverage of a channel, say like a state-wide police frequency. You have a receiver (hooked to a computer w/ RadioFeed) in City A, and the same in City B. Now you could just stream those both to radio reference separately (i.e. - "Whoville State - City A Barracks" and "Whoville State - City B Barracks"), but what would be better is if you could combine the two into one stream, "Whoville State Police".

So that's where streaming the two streams to a master comes in - combining the two streams into one before sending it to RadioReference. That in-and-of-itself could be a feature, combing several streams into one.

But then what happens if the two receivers can both hear some of the same stronger traffic, like the dispatcher? If they're not synchronized you'll hear an echo in the combined stream, or if it's really off, multiple repeats of the same traffic and then some traffic that's not repeated. It'll just be confusing. So that's where the GPS and time come in - use them to match up the independent streams (they won't be off by much, but could be several seconds, depending on the buffering, right?), combine them, and you get one wide-coverage stream that sounds like it's coming from a huge-coverage tower, but it's actually several simple local sites combined to make one.

These are interesting thoughts. It sounds like a lot of R&D is involved which can take months or more. I'm not sure the time-value is there. And I don't know if it will work at all by combining the audio. There will always be an echo if the audio not perfectly in sync (50 ms or less). I think the audio should be voted rather then combined but not really sure on that either for a multi-city system. I don't think I want to spend the time on R&D if the demand not there.

[EDIT] I just thought of something. If you are talking about the same radio traffic, then why combine the traffic in the first place? If different radio traffic then I don't think it's a good ideal to combine the streams at all as each other will step over the other.

Yeah, I figured the value wouldn't be there, but wanted to see what you thought.

Yeah, I was hoping the USB GPS was good enough to get at least that sort of timing. But yeah, voting seems like a great idea too. I *assume* modern voting systems that move data from remote sites over varied transports operate by doing something similar to this.

If you are talking about the same radio traffic, then why combine the traffic in the first place? If different radio traffic then I don't think it's a good ideal to combine the streams at all as each other will step over the other.

I guess the railroads are fairly unique in the way they operate, in that even though their coverage area can be several hundred miles long (requiring the multiple feed sites), there are still only 5 to 10 trains on the line, and they're all waiting to talk to the same dispatcher anyway. So since you've only got 5 to 10 users, and they more or less are all waiting to talk to the same guy, the traffic is pretty well ordered and low density.

I guess that's where my state police example went astray.

Anyway, thanks again for the great software.

When listening to my feed using the Loopback feature, I seem to experience a slowly increasing delay in the audio. After several minutes or hours of listening, I notice that the audio I hear is several or many seconds behind what is being received and decoded. All I have to do is check Loopback off and then back on, and that seems to catch it up instantly. Any idea what could be causing this?

BCD536HP & RadioFeed

I have my feed broadcasting over RadioFeed. My question is is there anyway to broadcast text Alpha tags as well with a BCD536HP? I don't have a serial cable so I'm using the USB cable that plugs into the front of the unit... Do I need The serial cable in order to do that?? Thanks!

 

[CommLt]

I know the rear serial cable works because thats what I use. I thought I tried the front and it didn't work but to be honest it has been so long I don't remember. If I get a chance I will test it again.

I tried it today and yes it does work. Plug in your USB cable and push the ".no" button.

Make sure the driver is installed

BCD536HP < UnidenMan4 < TWiki

Good luck.

I coulda sworn I already installed the Driver but I'll do it again and try it out. Is there any particular settings I need to do on RadioFeed? I would really love to broadcast Tags over ScannerCast but there is no option for BCD536HP, just the 996XT and the GSR-500. Thanks!

Firmware update

Okay, I went to the UnidenMan page link you sent me to. On the first page it says the Firmware is 1.03.03 released 2/28 with some fixes, however when I click the link to the Firmware update page it says Firmware version is 1.03.01 released 2/12... So has this page not been updated yet or is there a place I can download the newest Firmware version? When I try to update thru Sentinel, which is version 1.03.01 it says the firmware I have is current, but that isn't true if the firmware is supposed to be latest 1.03.03... :]

BCD536HP Alpha-Tags

Okay, I've finally got the Alpha tags to work over Radio Feed, just by installing the windows drivers, but now I have some other questions raised... When the tags are broadcasted for some reason they are coming in like five seconds quicker than the actual audio comes in so by the time the audio broadcasts when you listen to it the tag is already gone, is this normal? Do I need to slow down the baud rate or something on Radio Feed? Also another question, when I plug the cable in to the front USB port to broadcast the Alpha tags, the audio that broadcasts over my scanner feed is greatly reduced to barely audible! Is this normal as well or is there any settings I can change to fix this also? I really appreciate any and everybody's input that has experience this! :]

 

[CommLt]

The delay in audio is normal and a side effect of the technology and has nothing to do with Uniden, RR, or the software manufacturer.

I cannot speak to the audio issue since I didn't experience it. It may have to do with a known audio problem that you can search the forums for. Using the rear serial port my volume on my 536 is set to 8 and that seems to work well. Check the volume settings and or audio boost settings you may have on your sound card. That may help.

BCD536HP &amp; RadioFeed

Is anyone else using RadioFeed to broadcast audio with a BCD356HP and using the front USB port for alpha tags?? I'm having a huge problem with audio... When i disconnect the front USB and don't broadcast tags the volume s perfect on level 8... When i plug in the front USB and broadcast tags the volume cuts drastically and i have to boost my volume and make it 100 on the sound card and turn the scanner up to like 17 to get a decent volume level... Anyone have any input?? It's really driving me crazy and can't understand why plugging in the front USB makes such a difference with cutting the volume level down tremendously... Thanks to all... I'm broadcasting it over my feed now and it sounds like crap, compared to not broadcasting tags and being crystal clear... it sounds all echoey and digital non-stop when there's no transmissions instead of getting quiet in-between...

That sounds like you have a ground issue. Is your audio line decoupled, by a capacitor or transformer?

Okay I think I might have it fixed. I changed the audio output from the Record Out behind the radio to the Earphone jack on the front of the radio. You can listen to my feed now and hear good volume with alpha tags broadcasted... Now my only gripe is everytime a transmission starts and stops there's an annoying "pop" each time... Not sure what I can do about that but at least the audio is good with broadcasting tags now...

Try putting a capacitor in line.

[KSquelch]

Is it possible to broadcast metadata on RadioFeed and also have virtual control of the scanner with a PC? The virtual control that I'm talking about is what comes with ARC500PRO. Is it a feature in some other software? BTW, I'm using a PSR-500 scanner.

It depends. The issue is the serial port can only be accessed by one app at a time. RadioFeed can read the metadata (or channel info) from a text file or any running program caption (title) area. So if your remote control software writes the channel info to a file or the caption then you're good to go.

Thanks for fixing this.
