Thanks to all for the responses.
I do plan on getting an antenna and putting it in the attic. Currently I have just a cheap dipole antenna, but still better than what came with the rec.
As of last week I had the current firmware according to the website. The yammy has hd, but not rds.
As to distance, I think it's more a matter of being in the hills. I'm probably only a couple miles from many of the antennas, but not a direct line of sight. I'm comparing what I could get in Stereo on my Onkyo vs. what I can get in HD on the Yamaha.
I do like the idea of internet radio. I was thinking of getting a roku for streaming. I already have a panny blu ray and listen to pandora streaming through it.
