Before the days of cell phones, internet and satellite communication, there was high frequency radio communication. While non-radio personnel may not fully appreciate the technology, amateur ‘‘hams" and military radio operators know that when all else fails, amateur radio, and its military counterpart, work." Last weekend, the Army, Air Force, Navy, Marine Corps and Coast Guard co-sponsored their annual two-day event, The Armed Forces Day Military/Amateur Cross Band Communications Test, marking the event's 59th anniversary. Fifteen military facilities participated in this event, including the Andrews' High Frequency Centralized Network Control Station, which had 16 Team Andrews radio operators from the 89th Communications Squadron on air for 12 hours conducting voice checks with calling stations. ‘‘These tests give amateur radio operators -- and people listening on short-wave radios -- the opportunity to demonstrate their radio skills and receive recognition from the Department of Defense for making contact with one of the participating stations," said Airman 1st Class Robert Stroh, 89 CS radio operator and event organizer. ‘‘This year we received 262 radio checks from coast to coast and as far away as Belgium, Germany and Switzerland," Airman Stroh said.
