Hello, I'm 100 miles north in Cheyenne.

Any QAM tuner, such as the HDHR and the HD-5500 card should be able to receive 
these channels.

This is most likely correct.

The analog to digital switchover applies only to over-the-air broadcasting. 
Many cable systems will continue to provide analog channels, but there's no 
telling for how long. Some cable systems are trying to convince their 
subscribers that the FCC is mandating they they (the cable operators) switch 
to digital, which is not true.

You may be confused between the HD-PVR and the HDHR. The former is an 
HD-capable component input capture device, the latter is a dual tuner ATSC 
and QAM device.

HDHR = High Definition Home Run:


I have an HD-PVR and HD-3000 (an older version of the 5500). 

I also have an HDHR and I love it.

The HDPVR is only supported by very experimental drivers, you're better off 
waiting for the next Myth release.
