Mostly listen to Utility stations therefore which would be the best to
install: the ECSS board or the BWC unit (continuous bandwidth control)?

From what I recall, there were several production changes. It is
important to establish which version is in your hands first (serial
number) . Did you look inside the receiver to know for sure which
modules are installed ?

True - but if you like utes, ECSS is probably not terribly important
(that's like S-AM). The bandwidth control would probably be a better
choice.
