RE: SDR AIS available in OpenPlotter 2 - Sailoog - 2020-05-13 maximum gain is not always the best for AIS reception. It is ok for calibration but you should find your best gain. In next versions leaving the gain empty you will apply an auto gain.

In OpenCPN under the connections tab? I am just getting started with the OpenPlotter Basic distribution. RE: SDR AIS available in OpenPlotter 2 - Sailoog - 2020-05-23 This is an openplotter app, SDR VHF, not an openCPN plugin or feature. Manual under construction: https://openplotter.readthedocs.io/en/latest/sdr-vhf/sdr-vhf_app.html RE: SDR AIS available in OpenPlotter 2 - pabben - 2020-06-10 I have a realtek dvb-t rtl2832u and it was working fine in openplotter 1. Now i am unable to calibrate. After choosing device and clicking "inital ppm" it stops at "Allocatin 15 zero-copy buffers" and nothing more happens. I have left all fields blank. PPM is set to 13 manually (just a random number) *** Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001 Using device 0: Generic RTL2832U OEM Detached kernel driver Found Rafael Micro R820T tuner Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6 [R82XX] PLL not locked!

Allocating 15 zero-copy buffers RE: SDR AIS available in OpenPlotter 2 - Sailoog - 2020-06-16 remove that random number and left ppm blank. use 49.6 as gain. RE: SDR AIS available in OpenPlotter 2 - pabben - 2020-06-17 It seems like once i've entered a number i am unable to leave it blank. I can change, but not remove the PPM. Altso tried to set it to 0 and to uninstall/reinstall "SDR VHF" from settings. PPM: 0 Gain: 49.6 Still same result RE: SDR AIS available in OpenPlotter 2 - beholder77 - 2020-07-06 Hi everyone! I have RTL-SDR usb stick with self made "flower pot" antenna. I have calibrated the stick, found best ppm and AIS working like a charm, the OpenCPN screen is full of detected ships, but every vessel is class "A", but no class "B" ships at all I asked my marina neigbours to turn on their class "B" AIS transponders , but they are not detected despite nearest vessel in 10 meters away of me. Class "A" ships detecting more than 10 miles away... Could you please give me advice what else i able to try to detect "B" class ships RE: SDR AIS available in OpenPlotter 2 - Bikertje77 - 2020-08-02 Hi Guys, Purchased a SDR-RTL dongle V3 (a couple of days ago), installed the SDR VHF 2.1.1, calibrated and edited/entered values in AIS line. The AIS service shows active and running. In openplotter, I added UDP connection (127.0.0.1 and 10110) but no AIS info showing on the chart! I've been reading/surfing/consulting the web like crazy, can't find an answer? What am I missing? Do I need additional add-ons / plug-in to run the AIS service beside SDR VHF 2.1.1? Looking forward to you answers.

I do not understand this, where have you added this connection? you do not need to add any connection anywhere, openplotter-sdr-vhf will do all the job RE: SDR AIS available in OpenPlotter 2 - Bikertje77 - 2020-08-04 My bad Sailoog, I entered that info in opencpn (connections) not openplotter. The gps connection is also present there. Is SignalK needed to receive the ais data? Or just sdr-vhf? |
