ui::OptionsField match option value by ==, not >=.
...
I think I used >= to match baseband filter bandwidth, but then the options would all have to be in increasing order to do the right thing, which is not what another developer would expect!

AIS decoding and really bad UI.
...
The decoder needs a serious refactoring/decoupling.
The UI just dumps bits of the received packets into a console window, whcih scrolls too quickly in an AIS-dense area with a good antenna.
