We're a radio LP-1 in a market below the top 100 in Ohio.

NOAA's VHF network has very good coverage here, perhaps too good. I can faintly hear co-channel gurgling underneath the strongest VHF channel, so we will be investing in a directional rooftop antenna favoring the local NOAA transmitter soon, and if needed, some RF attenuators.

TTS has messed up the names of a few local towns. Try running the village "Gnadenhutten" through TTS (a fascinating German settlement established in 1772). The NOAA RF feed uses TTS as does the CAP/EAS configuration, so I don't see an incentive to go to CAP to get away from TTS, it is there in both modes.

During the time CAP has been a thing, there have been two known NOAA RF or TELCO failures attributable to NOAA versus several CAP failures attributable to the ISP (fiber to the CO). For us, RF is more reliable.

If suddenly the NOAA RF product was also available via CAP with the same exact content, I'd really have no strong preference for either. I'd use them both (and discard dupes) just to pick up a bit more reliability.

Sean touched on differentiating the content of a CAP feed. We're generally satisfied with NOAA's RF content, except for those rare times the message fills the two minute buffer or trys to make reference to a long web site URL.
