ATSC org doesn't make the rules for DRM.

But you at least get a voice at the ATSC table. Which can only be a positive.

very odd. 5 min ago I was getting 98 channels now it shows 83. I guess I have to invest in a lte/5g filter. which one is best for low-vhf. thanks.

fyi with the old antenna I was getting 120 channels.


EDIT: Looking at the specs for that antenna, it appears to have a preamp which already has a ...

That is correct. Matching is via public IP address and we don't know the public IPv4 address of a tuner that connects to our servers using IPv6.

Perhaps IPv6 capable devices (if they also have an IPv4 address) should also attempt to contact the servers via IPv4 to add those devices to the ...

Yes, I know SD recommends against using cloud based discovery (and I mostly don't use is, but I do offer it as an option for one of my apps). But I have observed a couple of what I consider to be anomalies (errors) in the results.

First, if one uses the IPv4 endpoint, or the default endpoint, which ...

The detailed dBmV / dB values are present within the current OTA tuners, they are just disabled unless you have a DEV unit. I upgraded to DEV units awhile back, it has helped me optimize my antennas immensely.


Well, then, maybe the TECH3-CC supports those additional values (nickk?)? If not, at ...

When I view the tuner status webpage for my Primes, signal strength in dBmV and signal quality in dB are displayed alongside the percentage equivalents. However, when I send a status.json request for the tuner, only the percentages are returned. Is it possible for the firmware to be enhanced to ...

Any ideas?


There are many possible issues. A few common WAGs include that a tuner "disappearing" can sometimes be due to a bad power supply, or a bad network connection. Check to see if the led's look correct. If you have a compatible power adapter, try that. If you have alternative network ...

Not to mention notch filters aren't perfect, something blocking out San Antonio's KNIC-DT on RF 18 will likely affect Austin's KGBS-CD on RF 19.


Extremely tight notch filters do exist (and have been used for commercial TV distribution systems). When I looked a decade or two ago they were in the ...

This isn't the first time this problem has surfaced on these forums.


Correct. And while various thoughts, ideas, and proposals, have been offered by the community over the years to provide owners of the tuners additional options, you are, for now, going to have to think outside the HDHR box for ...

If you could build a notch or band-stop filter[1] to knock down RF 18 that should stop it.


A single channel notch filter tends to be rather expensive commercially (if you can filter a larger band, rather than just one channel, it can end up cheaper). Building it yourself is always a possibility ...

Is there a way to tell from the device ID if a device is legacy or not? If it is not legacy and perhaps an edge case in my own system can the device ID show if the device is ATSC/QAM vs DVB-T/C?


The official definition of the algorithm for determining from the device id if a device is legacy ...

FANTASTIC response Nick! Detailed and complete, and even I could understand it. I think any FCC commissioner could understand it as well.


Just for the record, it is likely that no commissioner will ever actually read it.

While the FCC Commissioners are the leadership, and make the decisions ...

Does anyone serious not have a good lab bench power supply (yes, I do know that I am likely not the typical consumer).

It is indeed the power adapter, thanks for the advice. I've never had a plug die on my before, so I didn't consider it. Ordered a replacement, hopefully it won't take too long to arrive.


Most of the consumer priced power supplies[0] have a lifetime that is less than five years (because that is ...
