Artefacts on random recordings

[march]

Hi Guys ( Great product btw) Recordings are perfect on every channel. But I do get the odd recordings that are full of artefacts. I'm starting to lean on the 4 port USB hub i have. I actually went from an older one that had a lot more recordings that had artefacts to the newer one ( still 5 years old ) that had a lot less.
I'm starting to think i should have two ISB hubs and spread the load maybe and have two usb tuners on each instaead of 4 on the one usb hub.
Here are some logs when recording friends.

Friends_20200509_19001930  - worked
Friends_20200509_19302000 - didn't had artefacts all through it when replayed on TV

I said : I'm starting to think i should have two ISB hubs and meant USB Hubs, sorry.

You sent just snippets not logs and you didn't even include the information on the recording you said worked.

Although not always accurate your signal strength does appear low.

Hi, :
Friends_20200509_19001930  - worked
Friends_20200509_19302000 - had artefacts all through it when replayed on TV
Episodes after 20200509_19302000 that evening had artefacts all through them.
Full log re-attached.
Also what is the signal strength section or line i can look at[attachment=undefined]

And i think i see the strength bit :
locked=1, present=1, strength=90, quality=100 (took 0ms to check) Does this mean a good strength ?
locked=1, present=1, strength=20, quality=20 (took 0ms to check) Does this mean a low strength ?

Should it be about 90 all the time.?
If so then it maybe time to replace the antenna ? as i do have another TV connected to the same line and this may mean that when i use that tv it saps a bit more of the signal ? Its the only thing i can think of.

Go to Settings ... About ... There's a button to zip the logs ... Attach the zip file. Thanks.

hi yes thats all good and i am zipping the logs no dramas. Its getting them onto here. I preview post and attach as requested previousley. This worked with the smaller zip file you can see from this morning, but not the bigger ones. Will try again. Again i can zip the log file from NPVR no worries.
