Tablo 4th Gen initially setup with Roku Ultra and placing antenna indoors I was able to get most live broadcast channels with 32606 zip code. Mounted the antenna on the roof and all seemed ok and able to receive all my local networks ABC, NBC, FOX, PBS, CBS. But then after a rescan all the sudden 20.1 ABC started broadcasting the Univision Channel in Spanish? All of my guide data looks correct. I tried removing the channel and adding, soft/hard resets, power cycles, changing zip codes, making sure firmware was up to date ect. but nothing has brought ABC back. I also see Univision on my mobile phone using the Tablo App as well as when using the Roku so somehow the Tablo device is broadcasting Univision instead of ABC?
Try changing the zip code to one nearby and scan again. The Tablo isn’t broadcasting something different just tuned to a channel the guide thinks is ABC but isn’t.
Agree, but already tried changing the zip code to several nearby zip codes and rescanned but still the same issue.
Any chance you are picking up WSDW from Panama City? That is the only station on RabbitEars’ list of Univision affiliates that uses virtual channel 20-1. But it is a long way from you.
One of the big drawbacks of Tablo is that it does not let you manually add and remove channels by RF channel number. It does not even show you what RF channel number you are watching.
Ron, I think you nailed it! Not only am I picking up 20-1 Univision but also 20-2 Jewelry TV both seem to be from Panama City as you mentioned. I guess the $38 GE UltraPro antenna is pretty efficient on the roof. This also explains why ABC was working fine with the antenna inside the house before I roof mounted it. The issue is that I could not get 50-1 FOX unless I roof mount. The 20-1 that is the local ABC should have plenty of RF signal but maybe so much that it is RF overloading? Maybe I need an attenuator but not sure where to go at this point?
Which way is your antenna pointed? This RabbitEars compass plot shows where the transmitters are in relation to your zip code. RabbitEars.Info - Signal Search Map
There look to be stations both northeast and southwest of you. Maybe point the antenna southeast and tweak it one way or another to get the stations you want. That would put Panama City toward the back of the antenna.
I don’t know how Tablo decides which of two channels with the same virtual number to use. It could use them both since they have different RF channel numbers. No reason to think it would use the strongest one.
My antenna is pointed mostly South and East a little. Panama City is more North and West of me but the antenna may be partially omni directional in some orientations. I will try aiming the antenna differently and also I will try an attenuator just in case the local signal is overloaded so much that the Tablo is picking up the further station as it may have less digital packet loss vs the overloaded local station. Thanks for your help!
Here is what I’ve seen. And I haven’t monitored this on the new firmware. If there are 2 virtual channel that are the same virtual number but with different RF the gen 4 use to pick the RF with the highest RF. regardless of signal strength.
I live at the cusp of where the main RF is VHF and it has the strongest signal. But a sister translator that is UHF leaks into my location. Often it will pick the UHF over the main stations VHF even though the UHF is only 3 yellow bars.
During a scan you use to be able to watch both virtual channels show up in the scan list before the dups are eliminated.
