Hi folks,
newbie setting up MX890 and MRF-260.

I cannot figure out why I cannot get RF working, but IR works fine.
Setup is simple: Nvidia shield, Samsung TV and Denon Receiver.

The Nvidia shield is right next to the MRF-260, so I do not use an emitter and this works fine with Power ON/Off and browsing the menu.

The TV and AV have individual emitters. The emitters seem to be working as they flash whenever I press the remote button key. The emitters match the device, so when I press Power off for the AV only, the associated emitter to the AV only flashes.

If I set the CCP to use IR on the remote instead of RF - the TV/AV both work fine when I point the remote to the general area of these devices and press Power ON/Off.

I even changed the emitter and the MRF unit, since I have spares but no-go.
I am running out of ideas what I could be missing. Yes I did set the ID the back of the unit and the SW to match.

Appreciate any help I can get before I go nuts.
