Today I just had my HR-34 installed it was replacing my HR-24. What I had noticed with the HR-34 and AM-21.

1) AM-21 power blue LED does not turn off when the HR-34 turn off
With the Hr-24 the blue LED on the AM-21 does turn off
2) OTA channels I now get all channels that are available, which was not available with the HR-24, some of the channels that are display on the guide shows "regular programming" , no channel info.

3) The tech did a force download upgrade, but it did not load the version that has Pandora and power save.

The HR34 scans for OTA channels, the HR24 does not.
One minor clarification, the HR34 will scan for locals with the latest version of the AM21 the AM21N, which is what I'd expect to be provided for a new install or a new hardware accessory order from DirecTV. My original AM21 won't scan so it's installed on the HR24. The scan function isn't a big deal around here, but important to those who want channels not in the Tribune guide data (e.g. Canadian stations).

I was going by my own past experience and remembrance of old posts such as these:

Apparently this is a feature of the HR34 but only in combination with the AM21N. How can that be if the AM21 and the AM21N are the same electronically?

Are you using an AM21 or AM21N?

I have 2 HR34's. One has an AM21 attached to it while the other has an AM21N and the only one I have ever got to scan was the AM21N
Maybe the code has changed or something. Looks like a good retesting opportunity when the NBA finals aren't on.

My HR34 has an AM21 connected and it shows all channels in the area.

On second thought, maybe it was the AM21N originally connected, it scanned all, then I swapped them and now the AM21/HR34 combo gets the additional channels?

Dang, I just gave myself a weekend project to sort this out.

Yes, the AM21 and AM21N are identical electronically outside of the AM21N possibly having later generation or newer tuner chips and an insulating cap for the unused AC pigtail when used with the H25 receiver.

My HR34 and AM21 had been working well since I got the HR34 in December. One day last week however, the HR34 began to report that the OTA tuner had been lost. Thinking it was a problem with my antenna, I connected the lead that was hooked to the AM21 directly to my TV set. The TV's tuner worked fine and brought in all of the channels that the AM21/HR34 were bringing in and more. Then I thought perhaps that the AM21 had went bad, so I went and got my AM21N that I was using with one of my HR24's, I still had the same problem with the HR34/AM21N. I then decided to do a master reset on the HR34 (clear and erase everything) even after doing this, the HR34 refuses to recognize either the AM21 or the AM21N, when both of those tuners work with all of my HR24's. I called DirecTV about the issue, and was eventually referred to the case management department. I explained the problem to them, and they informed me that it was more than likely a problem with the HR34, but they were not allowed to just send out a HR34 replacement, that they would have to send a technician with one. So, they are supposed to send out a tech on Friday to take a look. I told them to make sure that he had another HR34, I hope he does, otherwise it is a lost trip for him, and a wasted afternoon leaving work early for me.

Excuse my ignorance, but what is an AM21???
An external box you connect to an HD receiver or DVR to add off-air stations. If you have local stations that DirecTV does not carry, an AM21 will let you get them, incorporate them into your guide, and record them with a DVR.

Let us know what you find out.

To all, Why is Directv saying that the AM21 and/or AM21N is not supported on the HR34? What makes it so hard on having existing external hardware , that they sell, be supported for all receivers? I think someone in charge for QA and Design phase on new products needs to be fired.

It's the HR34 that determines if an AM21/AM21N does the scanning, not the AM21/AM21N. I was an early tested for the HR34 and I tested both the AM21 and AM21N for scanning and both do it.

I missed that, who/where did it say the HR34 doesn't support the AM21/AM21N?
According to DirecTV, the AM21 and HR34 are compatible.

From page 4 of the AM21 OFF AIR TUNER Manual available at http://www.directv.com/learn/pdf/AM21_GuideBW_Web_092110.pdf:

Note: The following DIRECTV® Receiver models are
compatible with the USB Off-Air Tuner: DIRECTV Plus®
HD DVR (models HR21 and above, DIRECTV Plus® DVR
(R22 model only), DIRECTV® HD (models H21 and above) or
DIRECTV® Home Media Center.

That doesn't say the HR34 isn't supported. It says "models HR21 and above" and an HR34 is clearly above an HR21. Not to mention "DIRECTV Home Media Center" is the HR34.
