https://wiki.mikrotik.com/wiki/Manual:Spectral_scan only tells us "Currently, is NOT supported for Atheros 802.11ac chips (e.g. QCA98xx, IPQ-4018)", but it would be great if there was an explicit list of which devices support this functionality.
Or a conclusive way to tell if a particular chip is/isn't a Atheros 802.11ac chip.
E.g. does spectral scanning work on the hap ac lite? Seems like a reasonably priced device I could get just to monitor the wireless environment?
