Which board is that board?
Thanks for posting the picture of dongle with cover removed.
The picture you posted is that of AirNav dongle, but not clear which one.
They have Green (1090 MHz ADSB), Red (978 MHz UAT), Blue (162 MHz AIS) and Yellow(118 MHz AirBand) dongles
However as the filter is Taisaw 395, which has center frequency 159 MHz, most likely this is AIS Blue dongle.
