Tune to RF channel?

I'm losing 2.1 and 18.1 sometimes. Can I manually tune to the RF channels 11 and 23 which always works fine when attached to my tv.

If you are using HD Homerun, go to Settings -> Sources.
On the HDHR entry, click on the number of channels.
You will then see all of your channels and can disable the ones that are not good and mark the good ones as Favorites.


Not in Channels, no. Other software allows you to tune via RF channel number, or by frequency, but Channels is not that software.
