AIS Message #14 - message string truncation #2094

Closed madmanguruman closed 1 month ago

madmanguruman commented 2 months ago

For AIS message 14, the data display is not showing the message correctly.

Example: An AIS message 14 is encoded with the message MOB TEST and transmitted. SDRAngel receives and demodulates the message correctly.

Under the AIS Demodulator Received Messages display, we see:

NMEA:    !AIVDM,1,1,,,>>O`Uh0lt:1@E=@,2*2c
Data:    Safety message: M

Offline decoders show that the full message is encoded in the AIVDM string displayed by SDRAngel. Also, commercial VHF receivers are able to decode and display the full message.

Any chance you can copy and paste the contents of the Hex column, please?
