Last weekend was the annual "Field Day" event. Ham radio stations all over the country get on the air to test their emergency radio skills and equipment. Some are very elaborate operations, with major antenna systems, large generators and multiple stations -- all set up on Saturday just prior to the 24 hour event.
My Field Day participation was based on using a small radio with low output (QRP) and battery power. The HW-8 transceiver (the small green radio pictured above) puts out about 4 watts -- the same as a small night light! The battery is charged with a small solar panel.
During this years Field Day I operated between chores, shopping and sleeping, with about 8 hours of total operation. Even so, I made 82 contacts with stations as far away as Hawaii, Alaska, Texas, Ohio and Illinois.
