I’m in St Louis County, directly west of the city. I have a 3rd gen Tablo Dual 128GB.
FYI for anyone not in the STL broadcast region, channel 24 does exist OTA and has 8 subchannels. It is not a FAST channel.
I could have sworn that 24.7 & 24.8 had zero guide data before I checked just now, but both channels now have guide data as of 5 mins ago (2:35pm CST, May 27th). Clearly I’ve confused them with channel 25, as 25.7 & 25.8 have zero guide data. Checking them does show that these aren’t placeholders, they are live subchannels that are broadcasting. (25.8 being infomercials, it’s no loss. 25.7 is a Telemundo feed - which should be available on channel 45 but we apparently don’t get that).
I’ve checked on Roku, Android and the Windows Store app. Guide data loads for 24.8 regardless, as it does for all channels.
One thing I’d say is that I’ve had my Tablo for 3 years but only just started really using it as in the city, we had very poor OTA signal (and we had cable included in our apartment rental agreement). We moved a month ago to St Louis County, where the signal is pretty good, even with with heavy rain we had last night.
This could be poor signal as having the Tablo next to our TV, right in the middle of our apartment, lead to dropped signal and in some cases no guide data. It’s now on the 3rd floor, antenna is literally in the window pointing towards the city, where most if not all of the transmitters are.
That said, it’s possible something was amiss and pure chance has fixed the problem in the 24 hours or so since you originally posted. Try rescanning, that may help.
The only non-perfect signal channels we get are Ion on 46 and subchannels… but they all work fine.
