Lines on TX'd picture

Post by g3zgz » Mon Oct 09, 2017 8:48 am

Hi all,

I have noticed that when TXing I see occasional black lines on the picture - seems worse on "moving"video .

This could be described as a quick burst of ignition QRM on a 625 analogue TV!

Not very often, but I wonder if other users are getting the same effect?

Thanks

Dave.

Hi Dave

Yes, it's a known issue that I have been unable to cure. Mentioned here: https://wiki.batc.tv/201707221_Release_Note

I think that it is an issue with the linux driver for the EasyCap, but it's beaten me!
