The SHow DAte command displays the current date and time.
The SHow HAm command is used for callsign database lookups. Both the US and VE callbooks are supported. AR-Cluster builds its own callsign database from the FCC and Canadian published data. If your callbook information is wrong, contact your sysop and he can run a new callbook for the cluster in about 7 minuutes.
The SHow HEading displays the heading and distance to a position. The heading calculations use the latitude/longitude information that you have set with the Set/Station/LatLon command. A Show/Heading followed by a callsign will use the position of the callsign if one is found on the network; otherwise, the position will be used based on the country of the callsign. The position data used in performing the Show/Heading calculations is also displayed. Long path, LP, headings are also shown.
The SHow SUn command displays the sunrise and sunset. The following sun calculations are displayed: sunrise/sunset, civil twilight, nautical twilight and astronomical twilight. Sunrise/set is considered to occur when the sunís upper limb is 35 arc minutes below the horizon (this accounts for the refraction of the earthís atmosphere). Civil twilight starts/ends when the sunís center is 6 degrees below the horizon. Nautical twilight starts/ends when the sunís center is 12 degrees below the horizon. Astronomical twilight starts/ends when the sunís center is 18 degrees below the horizon.
A Show/Sun without any callsign defaults to sun data for your location if you have valid position information for your station. A Show/Sun followed by a callsign will use the position of the callsign if one is found on the network; otherwise, the position will be used based on the country of the callsign (CTY lookup). The position data used in performing the sun calculations is also displayed.
The Show/Sun command can also be used with an optional date parameter formatted as mm-dd-yyyy.
