Listen to GB3OA world-wide
All of GB3OA’s output is being streamed through Shoutcast, the internet audio streamer. To listen from anywhere in the world you can go to http://shoutcast.com and search for GB3OA.
‘….are there other ways I can listen to the stream?’
One other way to listen in is from this web site, by clicking on one of the players below:
However, note that when the stream is taken down temporarily for maintenance some players handle the start of the new stream differently. The answer is to refresh the player.
Our recommendation to listen in from a PC, Android, iPad or iPhone…..
After substantial testing we recommend using VLC Media Player by VideoLAN or VideoLABS. Look for this logo:It handles the stream well and doesn’t need refreshing after the stream has been taken down for maintenance. The PC version has extra features too (go to AUDIO > VISUALISATIONS).
To connect VLC to the stream you need to find OPEN NETWORK STREAM in the menu of the player and enter the following:
http://220.127.116.11:8350 – this is the new address
By using this address along with VLC itself, you’ll find that the stream remains solid even with a flaky wifi, 3G or internet feed.
Note that in the PC version in TOOLS > PREFERENCES > ALL > INPUT CODECS, that TCP CONNECTION TIMEOUT should be set to 5000, and NETWORK CACHING should be 1000. The latter can be increased if you have a particularly bad connection.
How is the audio stream generated?
Technically, the constant audio stream is achieved by feeding the receiver output from a Baofeng UV-3R HT into a 50p-sized USB soundcard which is connected to a Raspberry Pi. Two programs are used in the Pi – ALSAMIXER sets the audio level and DARKICE converts this audio into 32kbps MP3 audio and sends it to the Shoutcast server as data. With all this going on the load on the Pi CPU is only 13%.
Also, DARKICE has been compiled with the MP3 LAME encoder which processes the audio. Sometimes the audio via Shoutcast may sound better than direct through your own rig!
