short update from me:
This morning everything was turned off in terms of power (fuses)
in the PC with the Hauppauge Tv card and an Ubuntu hard drive clamped into it.
Result: disruptions .... p.s. The neighbor telephoned a few times, which roughly corresponds to the disruptions.
.
Then conversion of the PC with the Hauppauge Tv card with LibreELEC hard drive and the changes (tips from you .. comskip, tagged with metadata).
Result: ran flawlessly without problems from switching on 13:59 to 15:56 without errors = 2 hours,
then I guess it is set in Kodi at PVR & TV settings timer updates = 120min. That was the error.
but:
16:16 Error. Some neighbor came home talking or telephoning and I was outside for a short time. The terrace opens the door, did any interference signals come in ???
I'm getting stupid ... (aluminum hat ...)
then bum, bum, bum ....
Error at:
16:39, 16: 42,16: 47,17: 01,17: 05 and 17:12
errors occur every ~ 5-6 minutes.
the TV program in the time at ARD HD:
13:00Pfarrer Braun
14:30Hotel Heidelberg
16:00W wie wissen
16:30Deutschland -Reportage
17:00Tagesschau
17:10Brisant
none of this is fun anymore.
.
first another antenna cable must be found.
then look again whether something has changed.
if that still doesn't work, the cable man should come again.
p.s. : he was there maybe 20 minutes, put his measuring device into the antenna socket and that's it ... a long-term test would be better.
