[MSNoise] [EXTERNAL] Re: two channel types one station

[Flinders, Ashton]

Thanks Thomas! On a related note, if I want to remove frequency bands (or
implement new ones instead of old ones), do I need to delete the old bands
directly from the sql tables?

Does the "not used" flag in the band conf work?

thanks!
