Please don't take my answer out of context. The original question was with regards to a ATSC/QAM tuner for the AZbox, not just if some generic ATSC/QAM tuner exists. Are you aware of an ATSC/QAM tuner for the AZbox and if so could you provide a link?
My ATSC tuner is for the AZBox HD, not the Plus version, although I believe that the Plus version also exists.
I had to contact the factory directly in Portugal to obtain the product. The Miami dealer primarily supports South America. As far as I know, he doesn't carry the NTSC tuner, but he could probably place one on order if you're willing to wait.
The Product ID is: TM10AT_Rev 3.00 ATSC Tuner (Thomson Tuner with an LG 7th Generation processor). This drops into the AZBox HD tuner slot and connects to the main board with a short cable.
Here is My Test Report:

[FONT="]Critical Issues[/FONT]
- [FONT="]One of the local channels WICZ-HD (channel 40-1) and WBPN-DT, (channel 40-2) caused a pop-up message to appear several seconds after tuning to either stream: [/FONT]
[FONT="]“Problem occurs on the System”[/FONT]
[FONT="]“Please reboot Your System”[/FONT]
[FONT="]This problem re-occurred after rebooting the system and tuning to the same channel. None of the remaining channels exhibited this problem.[/FONT]
- [FONT="]Frequencies containing 3 streams could not display the third stream. When tuning to stream 3, the sound and video would appear for a second or less and would then switch to stream 1. The info screen would continue to show information for stream 3 after the sound and video switched. This occurred with all channels containing more than 2 streams.[/FONT]
[FONT="]Other Issues[/FONT]
- [FONT="]The FCC assigned channel numbers are not displayed. The channel frequency is available from the info display, but the channel number associated with this frequency is not listed.[/FONT][FONT="]
[/FONT]
- [FONT="]The Channel list displays the scanned order number instead of the TV Channel number. The FCC assigned TV Channel number should be displayed instead. The channel number is available from the PSIP packet data.[/FONT]
- [FONT="]Extended text program description information is not being displayed. Current Program / Next Program Names are displayed, but no Program Descriptions. This info is also available from the PSIP packet data.[/FONT]
- [FONT="]While scanning for Off-The-Air ATSC Channels, the tuner scanned to 887 MHz (formerly channel 83). The highest North American channel is 803 MHz (channel 69). Frequencies above channel 69 were allocated to cellular telephone and other services in the 1980s. [/FONT]
[FONT="]This is not a big issue since these frequencies may still be used by other countries.[/FONT]
[FONT="]Other Observations – not related to ATSC tuner[/FONT]
[FONT="]During boot-up the words “Command Failure” were displayed on the AZBox front panel display. This occurred just before the AZBox logo appeared on the TV screen. I have not observed this message with earlier versions of firmware.[/FONT]
