Looks to me like Web browser security is blocking unsigned java applets (.JAR files). .Jar files from un-trusted sources can be dangerous to your computer files. A signed applet has a tag in it that identifies the publisher and that it is valid...

I see a note related to links on the W9CF page as follows:

"Note: Oracle has changed the latest (2014) java browser plugins so that they require applets to be signed with certificates, verifying the signer's identity, from one of the trusted certificate authorities. These certificates cost between $80-$500 per year. The applets below have instead been signed with my expired free Thawte freemail certificate. You will get a security warning and will need to click "I accept the risk and want to run this application" if you want to run any of the applets below in your browser. You can download the jar files and run them as applications without these warnings. "

In order to run a .jar file from internet sources (http), you must install Java on your machine if it is not already installed. you can download Java from Oracle corporation...   https://www.java.com/en/

once i did this (just now), i was able to open and allow to run the jar file through this link http://fermi.la.asu.edu/w9cf/tuner/tuner.jar  i see an app that looks like a tuner (swr meter and three knobs).

My machine is windows 10.

Hope you find this useful.
