Radio Club Hosts Field Day to Test Emergency Communication

For over 24 hours, amateur radio operators communicate via voice and Morse code.

Howard Thompson, with the Germantown Fire Department explained.

"Despite the proliferation of cell phone, satellite and modern digital communications, any time theres a natural disaster or a manmade event such as 911 ham radio operators step up to the plate and provide emergency communications to more local community", Berkowitz said.

Members of the South Texas Amateur Radio Club met to set up field radio stations Saturday.

Ham radio operators are amateurs with licenses from the Federal Communications Commission.

These radio operators, often called "hams", provide backup communications for everything from the American Red Cross to FEMA and even for the International Space Station.

There are about 25 members in the Lawrence County club.

Saturday is what the organization calls 'Field Day'.

"The fastest way to turn a crisis into a total disaster is to lose communications", said Allen Pitts of the ARRL.

One thing I learnt was that FM receivers don't need an AGC, since the volume of a signal is related to how much it deviates from the central signal, not how much signal there is, which is why the microphone gain setting on your radio determines the volume, not the level of power.

There was a tent that offered novices a "chance to go on the air" with assistance by a ham, who will help them connect with someone they don't know out in the ether, and perhaps get them interested in the hobby, which can be done with an investment of only several hundred dollars. To be clear, enough of your signal needs to get to the other end for it to work, but after that, you're just wasting electrons.
