Can some point me where to start, I want to transmit AIS signal, the software and the hardware.

I just want anyone to give me hint of what software to use and how to encode the data and which hardware to implement to send that AIS signal at 162MHz throught a anteena which I can build(The anteena for transmitter and reciever should have same freq range right). I have already made the AIS reciever using RTL-sdr after watching the tutorials online but I don't have acsess to AIS transponder nor there are ships nearby. We are building this safety device which has AIS reciever for fishing vessel for a competion but I don't have a way to check it here. The place where we will present it will have AIS signals.

Troubleshooting Help • Re: Trouble receiving anything?


You said....I cranked the gain up full, but see absolutely no signals, not even noise. So your seeing no trace at all..kind of like you haven't hit the start/run button for that particular app?
Please post a screen capture.
Also Linux or Windows?
If linux.....type rtl_test in cmd window.

Joel, I have a solution, but I'm not anywhere near an expert. I'm sure there is a more elegant solution out there
I use an app called tmux. It's an extension of term. I started using it when using rtl_tcp.
Command line for /etc/rc.local

sudo -H -u pi tmux new -d -s openwebrx-session 'bash -c "cd /home/pi/openwebrx-uhf; ./openwebrx.py; bash"'
sudo -H -u pi tmux new -d -s openwebrx-session1 'bash -c "cd /home/pi/openwebrx-20m; ./openwebrx.py; bash"'
sudo -H -u pi tmux new -d -s openwebrx-session2 'bash -c "cd /home/pi/openwebrx-40m; ./openwebrx.py; bash"'
exit 0

There will be a million people that say you don't need the sudo.

I'm also using rasp jessie I believe

Newbie questions for the group... 1) Automatic Gain Control. Leave it on, or turn it off and control gain manually? 2) Overnight. Leave dongles mounted, or disconnect from USB?
