It's text and not video. Just speaking personally I wouldn't have clicked on or commented on a youtube video link. rtl-sdr.com is pretty decent aggregator as far as hobby SDR goes despite their bias in promoting their custom rtl-sdr dongle.
Yeah, I understand the preference for text, and I’m not against the site itself for posting it (I don’t have enough knowledge to comment on its quality), but I think we should give credit where credit (and ad revenue) is due, and link to the original creator’s work where possible.
In the vast majority of cases I prefer text, but in this specific case the video is actually useful for all the little details about what he’s doing that aren’t in this article or the words he’s using.
