its best to install both on your meter as KV may work now for 123.0w but doesnt mean it allways will, I found quite a few sats that would work on KV or KH but not both, this was using the latest download from birdog.tv
The Equity channels (RTNs, etc) on G-10R are all on vertical polarity. Nearly everything of interest on this satellite in Ku is vertical (exceptions being the UW, VA, and Research Channels)...
