Space Shuttle Radio Frequency List Rich Weinkauf, Farmington, MI 01/07/92 A Space Shuttle mission requires the coordination of thousands of individuals on the planet, and some off. This coordination is directed largely by radio communications, both voice and digital; and supplies the communications enthusiast with several opportunities for listening. The following list includes radio voice communication frequencies reported to be in use during a typical Space Shuttle mission. This list has been gleaned from many sources, including personal communications, messages on Prodigy, Amateur Radio Bulletin Boards, Space and Astronomy Bulletin Boards, and the NASA Spacelink BBS. All of it is subject to change without notice, and reception is dependent on your location and the propagation conditions. I can be reached for additions, deletions, and corrections to this list via: Packet radio: N8QLT @ WD8DWO.#semi.mi.us.na CompuServe: 70534,227 Internet: 70534.227@compuserve.com Prodigy: BNCG39A NASA: (frequencies in kHz, USB commonly) NASA booster rocket recovery: 2622, 11407 NASA tracking: 3385, 3395, 6983, 14456 NASA tracking vessels: 5190 NASA booster recovery vessels: 5810 NASA aircraft: 6708, 6896, 7461, 7765 NASA Kennedy operations: 7675 USAF Cape Radio: 10780, 20390 NASA Pacific operations: 11205 NASA tracking (Ascencion Island): 20186, 20191 Edwards AFB: (frequencies in MHz) 116.4 ATIS 120.7 control tower 121.8 ground control 126.1, 127.8 approach control 133.65 approach/departure control 138.45 commandpost 149.925 security 162.6125 NASA ops 164.1 NASA 173.5875 fire 236.6 control tower 269.9 ATIS 290.3 departure control 318.1 tower 348.7 approach control 372.2 dispatchers 390.1 ground control Kennedy: (MHz) 117.8 shuttle control 121.75, 126.3 ground control 126.65 weather 142.5, 143.04 cranes 148.455 NASA booster recovery 148.485 launch countdown/status 149.175 shuttle crawler 162.0125 NASA vessels 162.6125 NASA ops 163.4625, 163.4875 security 163.5125 security 163.5625 fire - primary 164.0 radiation checks 165.1875 check points 170.15 base operations 170.175 transportation 170.35 public relations 170.40 General Services Administration 171.15 maintenance/fuel 171.2625 camera tracking 173.175 security - gates 173.4375 medics 173.5625 fire/rescue 173.6625 safety units 173.6875 security - vans 173.7875 fire - secondary 284.0 ground control Patrick AFB: (MHz) 118.4 approach/departure control 121.7 ground control 125.1 approach control 126.2 control tower 128.8 dispatcher 138.3 command post 273.5 ATIS 335.8 ground control 340.9 approach/departure control 344.6 weather 348.4 control tower 358.3 approach control 372.2 dispatchers International emergency air frequencies (MHz) 121.5 243.0 Shuttle frequencies: (MHz) 296.8 primary 259.7 secondary 279.0 space suits Communications and other stuff: (MHz) 1831.8 primary (USAF uplink, phase modulation) 1775.1 secondary 2106.4 primary (NASA uplink, phase modulation) 2041.9 secondary 2205.0, 2250.0 NASA downlink (FM) 2287.5 primary (NASA downlink, voice, phase mod) 2217.5 secondary Contractors Rockwell (Edwards) 2995.5, 3282.5, 3475.5, 5597.5, 10010.5, 17966.5 (kHz, USB) 122.8, 123.05, 123.35, 123.525, 462.925 (MHz) Rockwell (Edwards/Kennedy) 123.475 (MHz) McDonnell Douglas (Edwards) 123.3, 123.55 (MHz) Com-Tech Associates (Kennedy) 151.955 (MHz) IBM & Harris Corp.

Most other contacts were with WA3NAN on 14295, 7185, and 3860, although QRM on 3860 made the signals difficult to copy by 0000 UTC. W5RRR was regularly heard on 14280 only, but with a strong signal.
