IBP(1) General Commands Manual IBP(1) NAME ibp - show which of the International Beacon Project beacons is trans- mitting SYNOPSIS ibp [arguments] DESCRIPTION IBP shows which of the beacons of the International Beacon Project is transmitting now. The following arguments can be used: a band expressed either in MHz (14, 18, 21, 24 or 28) or in meters (20, 17, 15, 12 or 10); if no band is specified, the program starts in multi-band mode. a Maidenhead locator (like JO32KF), to be used for the calculation of distance and azimuth (both short and long path) to each beacon. -c, --nocolour don't use colour, even on a colour terminal. -m, --morse display callsign of active beacon in morse code (not in multi- band mode). -x, --nograph don't open the X11 window (showing a world map with the beacon locations, and short and long paths) even if the DISPLAY envi- ronment variable is set. This option is only available if X11 support has been compiled in. Note: since each beacon transmission lasts only 10 seconds, your com- puter's clock should be set reasonably accurately for the results to be valid. THE INTERNATIONAL BEACON PROJECT The International Beacon Project is a set of 18 amateur (ham) radio transmitters around the world, each of which transmit every 3 minutes on a set of 5 short-wave frequencies. This allows short-wave radio users to quickly assess the current worldwide propagation conditions. Much more information can be found on http://www.ncdxf.org/beacons.html AUTHOR Pieter-Tjerk de Boer <pa3fwm@amsat.org>; via amateur packet-radio: PA3FWM @ PI8DAZ.#TWE.NLD.EU. The X11 display code is heavily based on the 'sunclock' program by John Mackin <john@cs.su.oz.AU>. IBP(1)
