When connected into a DX cluster you will
receive WWV spots in real time. You can
also query the database for past WWV spot information. As a user, you can also input WWV spots into
the network. The hour of each WWV spot
is aligned with the publication times of: 00, 03, 06, 09, 12, 15, 18, or 21. The scales used in WWV forecasts can be
found at http://www.sec.noaa.gov/NOAAscales/index.html.
As
soon as you connect into a DX Cluster you will automatically start receiving
WWV spots as they are posted into the network.
The
display of real-time WWV spots can be controlled with the following commands.
Examples:
set/nowwv_announcements
set/wwv_announcements
The SHOW/WWV command is used to query the
database for past WWV spots. You can get the last five WWV spots postings as
follows.
Example:
show/wwv
If more than the default five WWV spots are
desired, an optional number can be added at the end of the command.
Example:
show/wwv/10show/wwv/20
To post a WWV spot, enter the details in the
following syntax where “nn” are numbers.
wwv sf=nn,a=nn,k=nn,comment
Example:
wwv sf=174,a=2,k=3,very low;gf quiet
Several of the AR-Cluster nodes also participate in
a special version of Solar Announcements from the Solar Monitor. Contact you sysop for details. Thanks go to K1TTT for providing the Solar
Monitor spots on the AR-Cluster backbone.
Regular WWV announcements show up with expanded
text as:
Example:
To SOLAR de SolarMonitor <0303Z> : WWV @ 0302Z : SFI = 177 A =
5 K = 1
To SOLAR de SolarMonitor <0303Z> : Last 24 Hours: Solar activity was low.
The geomagnetic field was quiet to unsettled.
To SOLAR de SolarMonitor <0303Z> : Next 24 Hours: Solar activity will be low. The geomagnetic field will be quiet to unsettled.
Special announcements also appear as:
Example:
To SOLAR de SolarMonitor <2205Z> : ALERT
M-Class flare in progress, current magnitude = M1.0
