I am trying to set up my DVB-T Dongle in 0.15.1 to support AIS in OpenCPN. I went to the marina this evening to hook everything up.
The GPS works great and is plugged into the same powered hub as the DVB-T dongle.
I know the DVB-T dongle is getting recognized because here is the output from lsusb
pi@openplotter:~ $ lsusb
Bus 001 Device 007: ID 1546:01a7 U-Blox AG
Bus 001 Device 006: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
Bus 001 Device 005: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 004: ID 0bda:8178 Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I was able to perform the calibration and came up with the following values for gain and PPM
I have Channel A 161.975M selected
Gain = 49.6
Correction (ppm) = -16
I'm not sure whether the correction should be a negative number, but thats what the calibration tool spit out? I tried running it a time earlier and Correction (PPM) was around 5.2. I'm using the included antenna that came with the dongle and was in the Harbor right by San Diego Bay so I thought that I should be able to see an AIS target in the marina on OpenCPN, but nothing came up after enabling AIS monitoring.
Any suggestions are greatly appreciated.
Thanks.
