The reason why DirecTV stop selling the AM21 is that the manufacture of the AM21 which was Pace and that Pace was bought out by Arris last your around the time DirecTV stopped selling the AM21. Arris or DirecTV may have pulled the plug on the AM21 during the merger. So DirecTV may have not planned to end the AM21 and is now looking for another manufacture or planning to add the OTA tuners to their next gen recovers? Since the local stations are asking for more money to rebroadcast and DirecTV not being able to add the local stations sub channels I think it would be good thing to make locals an option again like DirecTV did when the locals were first offered. I think Dish is heading in that way with their new OTA usb tuner and is planning to offer the locals as an option again.
I opened the AM21N up using Torx security drivers (available on line) and got the manufacture of Pace and did some research to get this info. You would be surprised that AM21N box is way too big for the tuners pcb and could have be put in the Mini box. The added plug can be removed from the box easily and all you have to do us unplug it from the PCB and remove from Box.
The Am21 may be renamed the Arris Pace ZH4105 Satellite/ota set top box now that is now available on the Arris site.
