Russ Roberts's insight:

It takes all kinds of people to make life exciting.  This dialogue is symptomatic of a growing coarseness and lack of decency in everyday life.  You find these antagonistical types everywhere.  When I worked as a news reporter for a commercial broadcast station, I experienced everything from verbal harrassment to death threats.  Some people are never satisfied until they make life miserable for everyone around them.  Hard as it may be, just ignore these sociopaths...they thrive on attention.  Of course, if you take the threat seriously, collect your evidence and press charges.  Amateur Radio is not immune from the breakdowns that plague society these days.  Aloha de Russ (KH6JRM).

Kurt Röhlig DL3UXI notes that increasingly our vital radio spectrum is contaminated by electromagnetic interference.
Russ Roberts's insight:

The increasing amount of interference in the rf spectrum has prompted some German hams to raise the alarm with government officials.  Electromagnetic interference is becoming a world wide problem, since it can affect emergency communications, broadcasting, and even Amateur Radio.  Aloha de Russ (KH6JRM).

Major changes in audio broadcasting the topic of an AES forum | Audio T & M content from Broadcast Engineering | KH6JRM's Amateur Radio Blog | Scoop.it
The battle has been joined, with mobile devices, wireless microphones and other technologies still in development fighting traditional broadcast signals for bandwidth. AM radio could be the first to fall if not protected by the FCC.

Via David Hall
Russ Roberts's insight:

You can add Amateur Radio to the mix of endangered users if more spectrum is dedicated to commercial uses such as broadband, mobile radio, and public service communications.  Already, many commercial users are casting eyes on the spectrum above 450 MHz.  Use it or lose it.  Aloha de Russ (KH6JRM).

Chris Marshall's curator insight, November 4, 2013 4:31 PM

With this article it reflects the changes that are now faced by the Audio Broadcasting. The multiplatform cell phone market creates the new challenge for Audio Broadcasting. The pros to this article can be the music has such an impact on our lives that we find it nessecary to have it on our mobile devices. The cons to this article are that music quality is not meant to be enjoyed on the go and in our everyday lives. The concept of music was suppose to be enjoyed from a stationary place not enroute to the nearest shopping center.
