Tried to use it this morning. Didn't get any error messages but it wasn't receiving anything.

Me too. No error messages but does nothing on HTML5.  Been that way for a few days I think.

I have had loading issues with various websdr receivers in both Java and HTML5. I find if I hit reload at least 3 times things will start working.  I use a couple of different web browsers and it doesn't seem to discriminate.

Using Chrome browser 121 and HTML5.

Just tried it with Firefox. Worked. Closed browser. Tried it again and it didn't work. When it did work CHU was coming in on 3858 KHz. Their gizmo has a problem.
Also their web site says there were 41 active users somewhere and somehow  ;D

Here's a concept; maybe someone who feels they absolutely need this thing, send them an e-mail.

When in doubt, there's always the real thing:

Get a Pet Rock or a plastic play toy.

AND, there are dozens of SDR web sites that are just as good if not better.
I like the NA5B:

I've never had an issue with any Web SDR. Using my 75A-4 and R7 exclusively for QSOs may have something to do with it...not sure though.

As with last time this happened, clearing your browser's cache should do it. If you want to be more strategic, clear just the cookies related to k3fef.com

That's the fix. Good idea, really, to give your browser an enema on a regular basis.

I’ve heard CHU creeping in on other SDR’s in the NE area, on a few different 75m frequencies.

BE careful where you add a response. I had to edit your previous post because your response was in the middle of my post in the "QUOTE BOX"

Now 3 different browsers on my iPad, and none can access K3FEF SDR. Waterfall shows several question marks.
