Field Day is this weekend 6/27/2015: 2:00pm Saturday to 2:00pm Sunday.
If you're at all interested in Ham Radio this is your best opportunity to learn and have fun. Field Day is something of a public event. Clubs get extra points for:
* Setting up in a public location.
* Getting non-hams or inactive hams on the air
(Most set up a special "Get On The Air" (GOTA) station just for this.
* Having educational materials available for people that stop by.
* Announce the event in local media.
* Give ham license tests.
Find a Field Day set-up near you here. No need to call in advance. Just show up. They'll be setting up Saturday a.m. before operating which starts at 2:00pm.
For you non-hams, Field Day is a once a year event were we operate for 24hrs out of buildings and off the power grid. The point is to test equipment and skills in a situation very loosely simulating some sort of disaster. To make it interesting they make it a contest to see how many contacts you can make in 24hrs. You'll get to see a wide range of equipment all in one place. Our club will be doing pretty much everything: voice (line-of-sight and around the world skip), Morse code, digital modes (yes, we plug the radio into a laptop's sound card and send texts thousands of miles through the air) and my job is to try to make a contact off of one of the ham satellites orbiting the earth every 90 minutes.
Hams love to show off their stuff and get non-hams to make contacts. If you show up you'll be warmly welcomed.
