Sony Sat-HD100

[alec]

Hello Equipment Forum,
I have a Sony Sat-HD100 STB that has been working fine for 2 years. I'm trying to receive the CBS HD feed from downtown Milwaukee but can't get the channel 1.1 to show up on the guide. I use Directv and a huge Channelmaster antenna for OTA. I can easily get 4.1(NBC) and 10.2-6(PBS). Is there something I have to do to get this box to see channel 1.1?

TIA,

Alec
