Ok, I am new to Open Plotter. It's still too cold to spend much time on my boat. I do have an AIS receiver, and an antenna, but I want to integrate more. Which is more sensitive, the dAISy, or a generic SDR device? Which SDR device? And how to connect it? Just point me to a link and I'll get moving. I can test GPS and AIS from home while waiting for better weather. Thinking of compass module and directly controlling the auto pilot motor...
And wind speed/direction/depth if I can get those values from Seatalk, or maybe the Rarmarine has NMEA output...
It's difficult to say which is more sensitive because the important part here is the antenna. Both devices are SDR receivers and the only difference is that dAISy switches between the 2 AIS channels every x seconds and in OpenPlotter you select one of them and stay there. Personally I prefer to stay in one channel because some messages have more than one part and you can lose information if you switch. Both channels are redundant. These are only impressions because I never tested dAISy device.
We use this one: http://www.sailoog.com/en/product/usb-rtl-sdr-ais
For connecting just plug it into an USB Hub, calibrate and that's all.
