SDR AIS not calibrating OP2
#13
(2020-05-18, 01:46 PM)Sailoog Wrote: If you run "initial ppm" for hours probably you will be really close to the final ppm value, using the GSM band you just find the exact value but ppm is +/-7 tolerant.

If you get 1 ppm means that you have the Australian device or a clone and probably 1 is your final ppm.

You do not need the terminal. Using the GUI is the same you do with the terminal.


Sailoog - thanks again!

I set the PPM to 1 and the gain to 49.6 then set the port number (well just saved the default). Then I checked that there was an AIS connection in signal K but didn’t see anything on the page that shows live data (Data Browser - can’t remember). When I went into OpenCPN I did not see any AIS data so I rebooted and changed the antenna from the mast mounted Antenna to an antenna from a hand held unit that I had nearby.

From my mooring I can see the lake express (Lake Michigan fast ferry), so thought at least I would get that with the small antenna. I did and two other entries, not sure how far they were away.

I did try to get a radio check from 5 miles offshore using my mast mounted Antenna and got a weak and unreadable response. I need to find a meter to check how the antenna is working.
