Chat nick name

This field sets your nick name as it appears on any streaming channels you are watching when you are logged in as a member - by default it is set to "first name_call sign" and we would suggest you do not change it from this convention.

Stream Title

This field sets the name of your own personal stream that appears on the channel list under the main streamer menu. By default it is set to your callsign.

Stream output URL

This is the direct URL you can give to people to watch your stream. You cannot change this URL.
Note - the full URL is made up of the https address above the grey box PLUS the text in the grey box (which is the stream name) without any spaces between them.  

For example the stream name for the above screen shot is ""

Stream input URL

This is the input URL which must be put into your streaming encoder. You cannot change this URL and should not pass it on to anyone else.
Note - the full URL is "rtmp://" where callsign is the stream name listed in the first grey box and keykey is the key listed in the second grey box. The stream name and key are separated by a hyphen.

Streaming from the Portsdown

The Portsdown is already set up to stream to the streamer. Up to 8 stream names and keys can be set up on the Portsdown 4.

Then from the main Menu, select Output to, BATC Stream. Then you can select from one of the 8 streams by pressing the "Stream to" button on the Main Menu.

  • In the FMS URL: box put "rtmp://" (Note there is no / on the end)
  • In the Stream: box put your "callsign-key".

Using Vmix

For Vmix, put rtmp:// in the "URL" field and the stream name and key separated by a hyphen (for example g8gkq-abcxyz) in the "Stream Name or Key" field.

Using OBS

For OBS, put rtmp:// in the "URL" field and the stream name and key separated by a hyphen (for example g8gkq-abcxyz) in the "Stream key" field.

Using an H265 Encoder Box

The Chinese H265 / 264 encoder box (model ON-DMI-16D) can also stream using RTMP to the BATC streamer site while at the same time 'multi-casting' to your Pluto for RF transmission and streaming rtsp for local monitoring on VLC. However currently the BATC streamer will only accept H264 which means that your Pluto will also have to be set to H264 on the Pluto controller page. The encoder cannot produce H264 for the BATC streamer and H265 for Pluto at the same time.

The url for the RTMP stream to the BATC streamer is of the form:


One thing to be aware of is when entering the 6 character key make sure you get it correct - my key happened to contain character "I" capital i, which can be confused with lowercase L . Using capital i fixed the problem !

The error was caused by copying the key on paper from the RPI 7" LCD streamer where both characters look the same.

To see the output of the encoder box locally using VLC enter this url rtsp:// into VLC. This assumes your encoder box IP address is

Stream type

This selection determines if your stream appears as a member, repeater or special event stream in the streamer main channel list ( You cannot change this.

Stream options

  • "Stream listed" You can decide if your stream is listed in the streamer channel list (by default streams are not listed and this box should be ticked to use the stream).

  • The "Chat On" box is ticked by default; if you untick this, there will be no chat window associated with your stream.
  • "Guest chat log in" If ticked it means that non-BATC Members will be able to post in your chat window; all they need to do is type "/nick display-name" and their chat will appear labelled with "display-name" or whatever they have entered. It is recommended that you normally leave this box unticked to prevent abuse of the service and limit chat access to logged-in BATC members.

Streaming type

The Streaming Type sets the default video player type on the Live Stream page, this can be set to either Flash or HTML5.

Flash Player


  • Minimal delay (typically less than 1 second)


  • The user needs Flash Player plugin installed, and manually enabled.
    • If the webpage detects that Flash is not installed, the user will then be given a link to use HTML5 player to view the stream.

HTML5 Player


  • Plays without plugins on all modern desktop and mobile (phone/tablet) browsers


  • Long and variable delay (typically 10-20 seconds depending on user's browser)
