Many organizations offer awards for meeting certain goals within amateur radio (generally talking to other amateur radio operators in different locations using certain modes). Generally, these are excuses for getting on the air.
DX Century Club
The ARRL offers the DX Century Club (DXCC) award for contacting 100 DXCC entities (think countries). I received mine using a combination of HF bands and modes. I also have 20m DXCC and qualify for DXCC – Phone and DXCC – Digital.
Worked All States (WAS)
Worked All Continents (WAC)
The Worked All Continents award is from the IARU and recognizes stations who have contacted other stations in all continents. I received the IARU – RTTY award.
