mwdxer1 add the iGOcast app, (I think they have one) to your system
iGoCast - Live TV or like me run you streaming from an old laptop. (Does more then any box and can even do kodi) But it is like STIRR. But it has a few OTA channels beside just the two you want, It has AntennaTV,ThisTV,RetroTV,TCN(The Country Network),Justice Network,Buzzr,YouTooTV,NewsNet,Action Channel,Weather Network,Rev'n TV,SportsTV,BizTV,Nasa TV,RT America,NHK World DW News,CBN Network and Jewelery TV. Thats 19 more OTA tv channels plus some lower local OTA like 360North out of alaska,that are not in your area. But also iGOcast has some other stations like Cspan,Cspan2,Cspan3 and others. But it is also legal like STIRR.
P.S. Here are two more OTA channels you can get off the net you don't have that are pretty good. LightTV
Light TV - Light TV and this is a cozi affiliate that is local to me but is also on the internet,does have local sports and stuff included. Just click the arrow.
Watch Live! that puts you up too 21 more OTA you can catch but there is more out there you can subscribe to the TBN network and right there is 9 more OTA channels, Smileofachild,TBN,Juce,Salsa and so on. Hope this helps you in your quest for more good OTA channels.
