Deemphasis: Surplus button?

Postby 13dka » Tue Dec 13, 2016 12:44 pm

Could somebody please explain why there's an "OFF" selection for FM deemphasis, when the "DEEM" button is a toggle? I'd deem one of the two kind of redundant? :mrgreen:

We could start a poll, what other function buried in the menus could be the heir of that precious window real estate! :)

The "50uS", "75uS" and "OFF" are for broadcast WFM and SWFM. The "DEEM" is a toggle for all other FM modes.

Ah the light came on :idea: thanks! I (obviously) wasn't aware that NBFM uses emphasis too and just read up a bit on the topic, which also gave me at least one idea why you can turn that off in first place. Learned something today, thank you!
