The question "can I hear the space shuttle on HF?" is often asked. The answer is no, not directly. However, what we can hear are some of the interesting behind the scenes traffic working Cape Radio in support of these launches. Whoizit? Cape Radio is at Cape Canaveral Air Force Station. The facility is run by a private contractor who operates and maintains all the HF radio's for the Eastern Test Range (ETR), which is the official designation for the facility at Cape Canaveral AFS. The facility is actually located across the Banana River from the Kennedy Space Center (KSC) and is not affiliated with NASA in any way. However ETR, better known as Cape Radio, does support all shuttle launches and unmanned launch vehicles. What is heard? There are two nets on HF for every shuttle launch. The first is Safety of Range. This net is usually controlled by "DoD Cape" on a circuit set up by Cape Radio. There is usually a U.S. Navy ship tasked to "launch danger area support" on this net. Sometimes a U.S. Coast Guard cutter is also deployed to assist. The job of these ship's is to ensure that no planes or ship's are in the area where if a rocket would have to be destroyed, debris may fall. They generally ID by the ships name, such as "USS Moosbruger" (DD-980). Also on this net are KING 1, 2 and 3, the U.S. Air Force Air Rescue HC-130's, as well as some other assets. The second net which is active every launch is controlled by "BRD" or the Booster Recovery Director. The two Solid Rocket Boosters (SRB's) carried aloft by the shuttle are jettisoned at two minutes, seven seconds into the flight. They are retrieved from the Atlantic Ocean by special recovery vessels and returned for refurbishment and eventual reuse on future Shuttle flights. The BRD net coordinates the two SRB recovery ships; M/V Liberty Star (callsign WRPH) and M/V Freedom Star (callsign KRFB). What frequencies are used? These two nets can make use of any of the hundred or so HF frequencies available to the Eastern Test Range. However, early listening to ETR primary frequency 10780.0 kHz. as early as 16 to 24 hours before scheduled launch time, will reward the listener with Cape Radio giving the working frequencies for both nets as the assets check in. If you miss this, then its a hit and miss affair. Other shortwave listening One last way to catch shuttle action is to monitor comms via the Goddard Amateur Radio Club in Greenbelt, Maryland. "WA3NAN" retransmits the air-to-ground Space Shuttle communications for all non-classified shuttle missions on: 3860 kHz. (LSB); 7185 kHz. (LSB); 14295 kHz. (USB); 21395 kHz. (USB); and 28650 kHz. (USB) plus or minus 5 kHz. for interference. Internet Also, check this url for scheduled missions: www.ksc.nasa.gov...
