I did not expect this to work, and I was not disappointed, LOL.
I set my HR21/200 to IR
I put the receiver for an RCA D930 cone near my HR21, and connected the IR blaster too it and propped it in front of the IR receptor on the HR21
I reprogrammed my RC64R to RF mode while leaving my HR21 in IR
When I depress the keys on the RC64R remote when it's near the D930, I see the red LED inside flash and thru the camera on my phone, I can see the blaster flash in IR too.
The HR21 remains oblivious to the signals, unfortunately.
I'm curious what's wrong. The RF remote won't cause the LED to blink if it is more than a foot or so away from the cone, I'm thinking it's not on quite the correct frequency the transmit cone operates on. Also, does the DirecTV remote format the data in the commands differently in RF mode as compared to the IR mode ?
It would be great if this trick worked, seems like at one time (maybe even now?) it worked on the DISH side of the rode.
Does anyone know of a device that would function as described above on a DirecTV HR2X box ?? Handy if there is something that does it.
