EACapture (Linux): every job fails with 806 Tune Failed on 479 MHz

Post by tjsander »

Portland, OR. HDHR5-4K 1080644E, firmware 20261107, Linux script 1.0.0.0.

Every job I've been scheduled is ch479000000p0?format=dbg. The tuner returns 503 with 806 Tune Failed every time, including the Nov 17 eas.dbg job. ATSC 3.0 tunes fine on 587 MHz.

479 MHz is ATSC 1.0 here right now (MeTV). The only ATSC 3.0 entry on 479 is 141.1, which my latest scan didn't find, so it only shows up in show=all. The server seems to be scheduling jobs based on lineup entries the latest scan didn't find.

Also, the script logs only the bare 503. Logging X-HDHomeRun-Error would make failures like this easier to diagnose.

I'm in the PDX area as well. Running on Linux Mint 22.3. No problems with the script and it runs without errors.

I made sure I was on the latest firmware and did a rescan of the channels.

Fixed (if it is the problem I think it is) - please download the script again to get the latest script.

I installed it, but the issue is still reproducing. The update changes the script's local check, which now skips Subscribed: 0 entries. The script still sends the full show=all lineup, and the server still schedules everything on 479 MHz.

After the update I restarted and checked in again (HDHR5-4K 1080644E, Portland, OR). All 17 jobs in the new schedule are ch479000000p0?format=dbg, including the Nov 17 eas.dbg job. Every attempt on 479 so far has returned 503 / 806 Tune Failed. 479 MHz is still ATSC 1.0 here, and ATSC 3.0 works on 587 MHz.

The fix probably needs to be server-side. Maybe only frequencies with an ATSC 3.0 entry that was found in the most-recent scan?

Is there a way to factory reset and/or clear the stale channel entries from /lineup.html?show=all ?

This would likely repro for anyone who has run channel scans on the same device in different cities, unless there is some region check that clears stale entries.

Code: Select all
