My HR22 receiver has died after many years. It doesn't get past the receiver self check and there is no sound coming from the receiver such as hard drive or fan. D* is sending me a replacement and told me to discard the HR22 as they will not be requesting that to be returned as it has reached end of life. So that leads me to think that I will get either a HR23 or HR24 for replacement assuming the HR23 is still actively being distributed. Hopefully it will be the HR24 since I have the whole home set up.
