An example of an amateur radio station with four transceivers, amplifiers, and a computer for logging and for digital modes.

Amateur radio (also called ham radio) is the use of designated radio frequency spectra for purposes of private recreation, non-commercial exchange of messages, wireless experimentation, self-training, and emergency communication. The term "amateur" is used to specify persons interested in radio technique solely with a personal aim and without direct monetary or other similar reward, and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

Katy Amateur Radio Society How to Remove Trovi / Conduit / Search Protect Browser Hijack Malware If your computer has been hijacked with an obnoxious malware that won’t let you change your home page, there’s a strong chance you’ve been infected with the Trovi Search Protect malware, which used to be known as Conduit. Here’s how to remove it. How do you know this is malware? How Did You Get Infected?
