       ibp  -  show  which  of  the  International  Beacon  Project beacons is


       ibp [arguments]


       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  or  JO32),  to  be  used for the
       calculation of distance and azimuth (both short and long path) to  each

       -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
              environment 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
       computer’s clock should be set reasonably accurately for the results to
       be valid.

       Note: no net connection is required to use ibp.


       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.

       The X11 display code is heavily based on the ’sunclock’ program by John
