Ok, so forum pre-processor damages links. If you use my link, but copy and paste the text, not the link itself, it will work.
Use the second link, since the first one is already broken in the forum itself.
Let me try it this way - eevblog.com/forum/index.php?action=.xml;type=rss;limit=20;sa=news . Yep, just copy-paste this one.
And for completeness, link to all posted messages - eevblog.com/forum/index.php?action=.xml;type=rss . Be warned, it easily gets ~700 messages a day
