Frequency assignment

[DaveNF2G]

There are now 3 AIS channels, including a new narrowband ship/shore pair. Is there a way to know which channels AIS-catcher is monitoring? Is there a way to direct it to tune particular channel(s)?

I need to check but I think running with -v shows the channels being monitored:

The relevant switch is -c (docs)

-c AB — the default; tunes the standard ship/shore pair around 162 MHz (channels A and B)
-c CD — tunes the long-range pair around 156.8 MHz (channels 3/C and 4/D)

What is the 3rd channel you are referring to (ASM1 and ASM2 at 161.95 and 162 MHz)? We are not decoding these yet but we can do if we find some signals in the wild to build the decoder.

The new narrowband pair is

157.4125 Marine-AIS 3 - Ship
162.0125 Marine-AIS 4 - Shore
