Firmware 20201030 released
This firmware really, really doesn't work for me. After the upgrade the first two Quatro4K tuners are no longer available to Windows Media Center. While losing half of the OTA tuners for my DVR is bad enough - the real problem is that I lost the two good ones. All of my testing praising the ability of the Quatro4K to keep channels locked even in the face of multi-path were based on Tuners 0 and 1. After the upgrade I have several channels I can longer keep locked due to the use of Tuner 2.

(Note I am still on WMC due to the lack of full DRM support in the HDHomeRun DVR, as I use a Prime along with a Quatro4K (originally a first generation white HDHomerun, then a Duo, now Quatro4K).

How can I downgrade to the most previous firmware before 20201030? I looked around and can not find a link to the older firmware.

I seem to recall that two of the 4K tuners were supposed to be ATSC3, and the other two were ATSC1. Is that the case?

Yes, tuners 0 and 1 are ATSC 3.0 and tuners 2 and 3 ATSC 1.0

Yes, tuners 0 and 1 are ATSC 3.0 and tuners 2 and 3 ATSC 1.0
Tuners 0 and 1 can tune both ATSC 3.0 and ATSC 1.0, while tuners 2 and 3 are ATSC 1.0 only. The difference in hardware, at least in my testing, means that 0 and 1 apparently have an edge in multi-path rejection when tuning ATSC 1.0.

I found two older ATSC3 firmware files, one on my desktop and one on my laptop. Tried to load each, and while they gave an upgrade successful message, the firmware still shows 20201030.

OK, maybe it did downgrade. My WMC just picked up tuner 0...

All 4 tuners are the same for ATSC 1.0.

If I remember correctly WMC will pick tuners in order 0-3 or 3-0 depending on whether it is a live TV viewing or a recording.

Erp. I stand corrected!

In WMC the user controls the tuner order via Edit Channel and then Edit Sources. Tuners can be moved up or down in the order that you want them to be used.

That is how your most loyal customers can merge a cable channel with an OTA channel, and then alter it in case they need an OTA or cable tuner used first, second, etc. (Merge cable channel 4 with OTA 4.1, then specify a specific OTA tuner first if you have a great signal - or often the other way around - cable first because OTA is iffy.)

After this firmware upgrade some of the Quatro4K OTA tuners are being skipped on some channels, but I haven't figured out the pattern yet. The WMC order is being respected, but in some situations the third (in my case Tuner 2 of the Quatro4k) is being selected - which would be correct if the first two (Tuner 0 and 1 of the Quatro4K) were in use - but they are not. Perhaps something has changed with how the tuners report to clients that they are available. Maybe some of the ATSC3 tuners are getting "stuck" in use in such a way that it is not readily apparent.

Well, after more than two weeks of having the new Quatro4K tuners first in use for ATSC 1.0 broadcast channels, the new firmware embarrassed me tonight and all our WMC DVRed shows recorded tonight were hardly watchable.

How do I downgrade the firmware???

The firmware does not affect reception performance (and can't be downgraded).

If you are seeing a problem with WMC please enable "send diagnostic information" on the Advanced tab in HDHomeRun Setup, reproduce the problem, then post back with the Device ID of your HDHomeRun. Please stay watching the channel for a good 5 minutes.

Thank you for responding and making this a separate thread.

Weather conditions have changed the past few days such that multi-path hasn't been as big of an issue. So when I can replicate the problem, I will send the diagnostics.

I still don't understand why WMC is ending up tuning most OTA channels on Tuner 2, when 1 and 0 are configured in higher priority. I still think this either is firmware-related or is a byproduct of the ATSC 3.0 stations coming back on-line in Dallas this week.
