I have a DirecTV H20 (HD receiver) which has RF capabilities. Does anybody know what the channel needs to be set to for this? How do I go about finding it (without going through every channel setup possible?) I have a ProntoNG TSU3000 running RF to an RF Extender emitting IR to all my other components in my AV closet. The H20 receiver is the only piece of equipment in the closet that is natively RF. I would like to be able to keep it RF, since it is not close to the RF Extender.
