1. don't route anything back down the channel it came from.
2. and, in the process, fix some silly errors in routing converted rcmd PCs
You can use the tag 'all' to accept everything, eg:
- ann/spot 3 all
+ acc/spot 3 all
but this probably for advanced users...

-<P>From version 1.35 onwards neighbouring nodes are pinged at regular intervals (see

+<P>
+<P>This command allow you to estimate the likelihood of you contacting
+a station with the prefix you have specified. The output assumes a modest
+power of 20dBW and receiver sensitivity of -123dBm (about 0.15muV/10dB SINAD)
+<P>The result predicts the most likely operating frequencies and signal
+levels for high frequency (shortwave) radio propagation paths on
+specified days of the year and hours of the day. It is most useful for
+paths between 250 km and 6000 km, but can be used with reduced accuracy
+for paths shorter or longer than this.
+<P>The command uses a routine MINIMUF 3.5 developed by the U.S. Navy and
+used to predict the MUF given the predicted flux, day of the year,
+hour of the day and geographic coordinates of the transmitter and
+receiver. This routine is reasonably accurate for the purposes here,
+with a claimed RMS error of 3.8 MHz, but much smaller and less complex
+than the programs used by major shortwave broadcasting organizations,
+such as the Voice of America.
+<P>The command will display some header information detailing its
+assumptions, together with the locations, latitude and longitudes and
+bearings. It will then show UTC (UT), local time at the other end
+(LT), calculate the MUFs, Sun zenith angle at the midpoint of the path
+(Zen) and the likely signal strengths. Then for each frequency for which
+the system thinks there is a likelihood of a circuit it prints a value.
+<P>The value is currently a likely S meter reading based on the conventional
+6dB / S point scale. If the value has a '+' appended it means that it is
+1/2 an S point stronger. If the value is preceeded by an 'm' it means that
+there is likely to be much fading and by an 's' that the signal is likely
+to be noisy.
+<P>By default SHOW/MUF will show the next two hours worth of data. You
+can specify anything up to 24 hours worth of data by appending the no of
+hours required after the prefix. For example:-

+<sect1>Telnet echo
+
+<P>
+Cluster links in particular suffer greatly from the presence of telnet echo.
+This is caused by the telnet negotiation itself and can create at worst severe
+loops. At best it creates unnecessary bandwidth and large logfiles! There are
+things that can be done to limit this problem but will not always work dependent
+on the route taken to connect.
+
+<P>
+Telnet echo itself should only be a problem if the connection is being made to
+the telnet port (23). This port uses special rules that include echo negotiation.
+If the connection is to a different port, such as 8000, this negotiation does
+not happen and therefore no echo should be present.
+
+<P>
+Sometimes it is not possible to make a direct connection to another node and this
+can cause problems. There is a way of trying to suppress the telnet echo but
+this will not always work, unfortunately it is difficult to be more specific.
+Here is an example of what I mean ...
+
+<tscreen><verb>
+timeout 35
+abort (Busy|Sorry|Fail)
+connect telnet mary.lancs.ac.uk
+'ogin:' 'gb7mbc'
+'word:' 'mypasswd'
+'\$' 'stty -echo raw'
+'\$' 'telnet 44.131.93.96'
+'connect' ''
+</verb></tscreen>
+
+So, the first connection is made by Spider. This is fine as Spider uses the
+Net_Telnet script from within perl. This actually uses TCP rather than TELNET
+so no negotiation will be done on the first connection. Once connected to
+mary.lancs.ac.uk, the command is sent to suppress echo. Now a telnet is made
+to a cluster node that is accepting connections on port 23. The problem with
+this link is that the negotiation is made by the remote machine, therefore you
+have no control over it. The chances are that this link will create echo and
+there will be no way you can stop it.

+
+<sect>Filtering (New Style v1.45 and later)
+
+<sect1>General filter rules
+
+<P>
+Upto v1.44 it was not possible for the user to set their own filters. From
+v1.45 though that has all changed. It is now possible to set filters for just
+about anything you wish. If you have just updated from an older version of
+DXSpider you will need to update your new filters. You do not need to do
+anything with your old filters, they will be renamed as you update.
+
+<P>
+There are 3 basic commands involved in setting and manipulating filters. These
+are <em>accept</em>, <em>reject</em> and <em>clear</em>. First we will look
+generally at filtering. There are a number of things you can filter in the
+DXSpider system. They all use the same general mechanism.
+
+<P>
+In general terms you can create a 'reject' or an 'accept' filter which can have
+up to 10 lines in it. You do this using, for example ...
+
+<tscreen><verb>
+accept/spots .....
+reject/spots .....
+</verb></tscreen>
+
+where ..... are the specific commands for that type of filter. There are filters
+for spots, wwv, announce, wcy and (for sysops) connects. See each different
+accept or reject command reference for more details.
+
+There is also a command to clear out one or more lines in a filter. They are ...
+
+<tscreen><verb>
+clear/spots 1
+clear/spots all
+</verb></tscreen>
+
+There is clear/xxxx command for each type of filter.
+
+<P>
+and you can check that your filters have worked by the command ...
+
+<tscreen><verb>
+show/filter
+</verb></tscreen>
+
+<P>
+For now we are going to use spots for the examples, but you can apply the same
+principles to all types of filter.
+
+<sect1>Types of filter
+
+<P>
+There are two main types of filter, <em>accept</em> or <em>reject</em>. You
+can use either to achieve the result you want dependent on your own preference
+and which is more simple to do. It is pointless writing 8 lines of reject
+filters when 1 accept filter would do the same thing! Each filter has 10
+lines (of any length) which are tried in order. If a line matches then the
+action you have specified is taken (ie reject means ignore it and accept
+means take it)
+
+<P>
+If you specify reject filters, then any lines that arrive that match the filter
+will be dumped but all else will be accepted. If you use an accept filter,
+then ONLY the lines in the filter will be accepted and all else will be dumped.
+For example if you have a single line <em>accept</em> filter ...
+
+<tscreen><verb>
+accept/spots on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
+</verb></tscreen>
+
+then you will <em>ONLY</em> get VHF spots <em>from</em> or <em>to</em> CQ zones
+14, 15 and 16.
+
+<P>
+If you set a reject filter like this ...
+
+<tscreen><verb>
+reject/spots on hf/cw
+</verb></tscreen>
+
+Then you will get everything <em>EXCEPT</em> HF CW spots. You could make this
+single filter even more flexible. For example, if you are interested in IOTA
+and will work it even on CW even though normally you are not interested in
+CW, then you could say ...
+
+<tscreen><verb>
+reject/spots on hf/cw and not info iota
+</verb></tscreen>
+
+But in that case you might only be interested in iota and say:-
+
+<tscreen><verb>
+accept/spots not on hf/cw or info iota
+</verb></tscreen>
+
+which achieves exactly the same thing. You should choose one or the other
+until you are comfortable with the way it works. You can mix them if you
+wish (actually you can have an accept AND a reject on the same line) but
+don't attempt this until you are sure you know what you are doing!
+
+<P>
+You can arrange your filter lines into logical units, either for your own
+understanding or simply convenience. Here is an example ...
+
+<tscreen><verb>
+reject/spots 1 on hf/cw
+reject/spots 2 on 50000/1400000 not (by_zone 14,15,16 or call_zone 14,15,16)
+</verb></tscreen>
+
+What this does is to ignore all HF CW spots and also rejects any spots on VHF
+which don't either originate or spot someone in Europe.
+
+<P>
+This is an example where you would use a line number (1 and 2 in this case), if
+you leave the digit out, the system assumes '1'. Digits '0'-'9' are available.
+This make it easier to see just what filters you have set. It also makes it
+more simple to remove individual filters, during a contest for example.
+
+<P>
+You will notice in the above example that the second line has brackets. Look
+at the line logically. You can see there are 2 separate sections to it. We
+are saying reject spots that are VHF or above <em>APART</em> from those in
+zones 14, 15 and 16 (either spotted there or originated there). If you did
+not have the brackets to separate the 2 sections, then Spider would read it
+logically from the front and see a different expression entirely ...
+
+<tscreen><verb>
+(on 50000/1400000 and by_zone 14,15,16) or call_zone 14,15,16
+</verb></tscreen>
+
+The simple way to remember this is, if you use OR - use brackets. Whilst we are
+here CASE is not important. 'And BY_Zone' is just the same as 'and by_zone'.
+
+As mentioned earlier, setting several filters can be more flexible than
+simply setting one complex one. Doing it in this way means that if you want
+to alter your filter you can just redefine or remove one or more lines of it or
+one line. For example ...
+
+<tscreen><verb>
+reject/spots 1 on hf/ssb
+</verb></tscreen>
+
+would redefine our earlier example, or
+
+<tscreen><verb>
+clear/spots 1
+</verb></tscreen>
+
+To remove all the filter lines in the spot filter ...
+
+<tscreen><verb>
+clear/spots all
+</verb></tscreen>
+
+<sect1>Filter options
+
+<P>
+You can filter in several different ways. The options are listed in the
+various helpfiles for accept, reject and filter.
+
+<sect1>Default filters
+
+<P>
+Sometimes all that is needed is a general rule for node connects. This can
+be done with a node_default filter. This rule will always be followed, even
+if the link is isolated, unless another filter is set specifically. Default
+rules can be set for nodes and users. They can be set for spots, announces,
+WWV and WCY. They can also be used for hops. An example might look like
+this ...
+
+<tscreen><verb>
+accept/spot node_default by_zone 14,15,16,20,33
+set/hops node_default spot 50
+</verb></tscreen>
+
+This filter is for spots only, you could set others for announce, WWV and WCY.
+This filter would work for ALL nodes unless a specific filter is written to
+override it for a particular node. You can also set a user_default should
+you require. It is important to note that default filters should be
+considered to be "connected". By this I mean that should you override the
+default filter for spots, you need to add a rule for the hops for spots also.
+
+<sect1>Advanced filtering
+
+<P>
+Once you are happy with the results you get, you may like to experiment.
+
+<P>
+The previous example that filters hf/cw spots and accepts vhf/uhf spots from EU
+can be written with a mixed filter, for example ...
+
+<tscreen><verb>
+rej/spot on hf/cw
+acc/spot on 0/30000
+acc/spot 2 on 50000/1400000 and (by_zone 14,15,16 or call_zone 14,15,16)
+</verb></tscreen>
+
+Note that the first filter has not been specified with a number. This will
+automatically be assumed to be number 1. In this case, we have said <em>reject all
+HF spots in the CW section of the bands but accept all others at HF. Also
+accept anything in VHF and above spotted in or by operators in the zones
+14, 15 and 16</em>. Each filter slot actually has a 'reject' slot and
+an 'accept' slot. The reject slot is executed BEFORE the accept slot.
+
<P>
-I am not going to spend any more time on these filters now as they will become more "comprehensive" in the near future.
+It was mentioned earlier that after a reject test that doesn't match, the default
+for following tests is 'accept', the reverse is true for 'accept'. In the example
+what happens is that the reject is executed first, any non hf/cw spot is passed
+to the accept line, which lets through everything else on HF. The next filter line
+lets through just VHF/UHF spots from EU.
+

-DBCREATE allows you to define a database in the system. It doesn't actually
-create anything, just defines it.
-
-The databases that are created are simple DB_File hash databases, they are
-therefore already 'indexed'.
+The next step will create a brand new 'spider' directory in your current
+directory.
-You can define a local database with the first form of the command eg:
-
- DBCREATE oblast
+<verb>
+cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/DXSpider co spider
+</verb>
-You can also chain databases with the addition of the 'chain' keyword.
-This will search each database one after the other. A typical example
-is:
+This command is all on one line.
- DBCREATE sdx_qsl chain sql_ad
+<P>
+Hopefully your screen should show you downloading files. The -z3 simply compresses
+the download to improve speed.
+When this has finished, you will have exactly the same as if you had untarred a full
+tarball PLUS some extra directories and files that CVS needs to do the magic that
+it does.
-No checking is done to see if the any of the chained databases exist, in
-fact it is usually better to do the above statement first then do each of
-the chained databases.
+<P>
+Now if you are doing a new installation, that's it. Carry on as if you have
+just downloaded and untarred the lastest tarball.
-Databases can exist offsite. To define a database that lives on another
-node do:
+<P>
+If you want to upgrade your current installation then do this ...
- DBCREATE buckmaster remote gb7dxc
+<tscreen><verb>
+tar cvfz /tmp/s.tgz spider
+cd /
+tar xvfzp /tmp/s.tgz
+</verb></tscreen>
-Remote databases cannot be chained; however, the last database in a
-a chain can be a remote database eg:
+This is assuming you downloaded to the /tmp directory of course.
- DBCREATE qsl chain gb7dxc
+<P>
+NOTE: the 'p' on the end of the 'xvfz' is IMPORTANT! It keeps the permissions
+correct. YOU WERE LOGGED IN AS THE USER SYSOP WEREN'T YOU?????
-To see what databases have been defined do:
+Remember to recompile the C client (cd /spider/src; make)
- DBAVAIL (or it will have been aliased to SHOW/COMMAND)
+<P>
+At this point the files have been upgraded. You can (usually) restrt the cluster
+in your own time. However, if you attempt to use any new commands or features
+expect it to be fatal! At least your cluster will have been restarted then so it
+will be too late to worry about it!
-It would be normal for you to add an entry into your local Aliases file
-to allow people to use the 'SHOW/<dbname>' style syntax. So you would

+</tt>
+
+<P>
+DBCREATE allows you to define a database in the system. It doesn't actually
+create anything, just defines it.
+
+The databases that are created are simple DB_File hash databases, they are
+therefore already 'indexed'.
+
+You can define a local database with the first form of the command eg:
+
+ DBCREATE oblast
+
+You can also chain databases with the addition of the 'chain' keyword.
+This will search each database one after the other. A typical example
+is:
+
+ DBCREATE sdx_qsl chain sql_ad
+
+No checking is done to see if the any of the chained databases exist, in
+fact it is usually better to do the above statement first then do each of
+the chained databases.
+
+Databases can exist offsite. To define a database that lives on another
+node do:
+
+ DBCREATE buckmaster remote gb7dxc
+
+Remote databases cannot be chained; however, the last database in a
+a chain can be a remote database eg:
+
+ DBCREATE qsl chain gb7dxc
+
+To see what databases have been defined do:
+
+ DBAVAIL (or it will have been aliased to SHOW/COMMAND)
+
+It would be normal for you to add an entry into your local Aliases file
+to allow people to use the 'SHOW/<dbname>' style syntax. So you would
+need to add a line like:-
+
+<tscreen><verb>
+ 's' => [
+ ..
+ ..
+ '^sh\w*/buc', 'dbshow buckmaster', 'dbshow',
+ ..
+ ..
+ ],
</verb></tscreen>
-It will interrupt the cluster just after the debug command has finished.

+so that users can use the more familiar AK1A style of enquiry such as:
+
+<verb>
+ SH/BUCK G1TLH
+</verb>
+

-changes to take effect.
+From version 1.35 onwards neighbouring nodes are pinged at regular intervals (see
+SET/PINGINTERVAL), usually 300 seconds or 5 minutes. There is a 'pump-up'
+counter which is decremented on every outgoing ping and then reset to
+the 'obscount' value on every incoming ping. The default value of this
+parameter is 2.
-<sect1>load/bands (9)
+What this means is that a neighbouring node will be pinged twice at
+(default) 300 second intervals and if no reply has been heard just before
+what would be the third attempt, that node is disconnected.
+
+If a ping is heard then the obscount is reset to the full value. Using
+default values, if a node has not responded to a ping within 15 minutes,
+it is disconnected.

<P>
-Connect a node to your system in such a way that you are a full protocol
-member of its network and can see all spots on it, but nothing either leaks
-out from it nor goes back into from the rest of the nodes connected to you.
+This command allow you to estimate the likelihood of you contacting
+a station with the prefix you have specified. The output assumes a modest
+power of 20dBW and receiver sensitivity of -123dBm (about 0.15muV/10dB SINAD)
+
+The result predicts the most likely operating frequencies and signal
+levels for high frequency (shortwave) radio propagation paths on
+specified days of the year and hours of the day. It is most useful for
+paths between 250 km and 6000 km, but can be used with reduced accuracy
+for paths shorter or longer than this.
+
+The command uses a routine MINIMUF 3.5 developed by the U.S. Navy and
+used to predict the MUF given the predicted flux, day of the year,
+hour of the day and geographic coordinates of the transmitter and
+receiver. This routine is reasonably accurate for the purposes here,
+with a claimed RMS error of 3.8 MHz, but much smaller and less complex
+than the programs used by major shortwave broadcasting organizations,
+such as the Voice of America.
+
+The command will display some header information detailing its
+assumptions, together with the locations, latitude and longitudes and
+bearings. It will then show UTC (UT), local time at the other end
+(LT), calculate the MUFs, Sun zenith angle at the midpoint of the path
+(Zen) and the likely signal strengths. Then for each frequency for which
+the system thinks there is a likelihood of a circuit it prints a value.
+
+The value is currently a likely S meter reading based on the conventional
+6dB / S point scale. If the value has a '+' appended it means that it is
+1/2 an S point stronger. If the value is preceeded by an 'm' it means that
+there is likely to be much fading and by an 's' that the signal is likely
+to be noisy.
+
+By default SHOW/MUF will show the next two hours worth of data. You
+can specify anything up to 24 hours worth of data by appending the no of
+hours required after the prefix. For example:-
-You can potentially connect several nodes in this way.
+<verb>
+ SH/MUF W

-You can see which nodes are isolated with the show/isolate (1) command.

+from now on for the next few hours.
-You can use this command to set a different interval. Please don't.
+If you use this command without a satellite name it will display a list
+of all the satellites known currently to the system.
-But if you do the value you enter is treated as minutes up 60 and seconds
-for numbers greater than that.
+If you give a name then you can obtain tracking data of all the passes
+that start and finish 5 degrees below the horizon. As default it will
+give information for the next three hours for every five minute period.
-This is used also to help determine when a link is down at the far end
-(as certain cluster software doesn't always notice), see SET/OBSCOUNT
-for more information.
+You can alter the number of hours and the step size, within certain
+limits.
-<sect1>set/privilege (9)
+Each pass in a period is separated with a row of '-----' characters
+
+So for example:-
+
+<verb>
+SH/SAT AO-10
+SH/SAT FENGYUN1 12 2
+</verb>
+
+<sect1>show/sun (0)
<P>
<tt>
-<bf>set/privilege <n> <call> [<call> ...]</bf> Set the privilege level on a call
+<bf>show/sun [<prefix>|<callsign>]</bf> Show
+sun rise and set times
</tt>
<P>
-Set the privilege level on a callsign. The privilege levels that pertain
-to commands are as default:-
+Show the sun rise and set times for a (list of) prefixes or callsigns,
+together with the azimuth and elevation of the sun currently at those
+locations.
-<tscreen><verb>
- 0 - normal user
- 1 - allow remote nodes normal user RCMDs
- 5 - various privileged commands (including shutdown, but not disc-
- connect), the normal level for another node.
- 8 - more privileged commands (including disconnect)
- 9 - local sysop privilege. DO NOT SET ANY REMOTE USER OR NODE TO THIS
- LEVEL.
-</verb></tscreen>
+If you don't specify any prefixes or callsigns, it will show the times for
+your QTH (assuming you have set it with either SET/LOCATION or SET/QRA),
+together with the current azimuth and elevation.
-If you are a sysop and you come in as a normal user on a remote connection
-your privilege will automatically be set to 0.
+If all else fails it will show the sunrise and set times for the node
+that you are connected to.
-<sect1>set/password (9)
+For example:-
+
+<verb>
+ SH/SUN
+ SH/SUN G1TLH K9CW ZS
+</verb>
+
+<sect1>show/time (0)
<P>
<tt>
-<bf>set/password <callsign> <string></bf> Set a users password
+<bf>show/time [<prefix>|<callsign>]</bf> Show
+the local time
</tt>
<P>
-The password for a user can only be set by a full sysop. The string
-can contain any characters but any spaces are removed (you can type in
-spaces - but they won't appear in the password). You can see the
-result with STAT/USER. The password is the usual 30 character baycom
-type password.
+If no prefixes or callsigns are given then this command returns the local
+time and UTC as the computer has it right now. If you give some prefixes
+then it will show UTC and UTC + the local offset (not including DST) at
+the prefixes or callsigns that you specify.
-<sect1>set/sys_qra (9)
+<sect1>show/wcy (0)
<P>
<tt>
-<bf>set/sys_qra <locator></bf> Set your cluster QRA locator
+<bf>show/wcy</bf> Show the last 10 WCY broadcasts<newline>
+<bf>show/wcy <n></bf> Show the last <n> WCY broadcasts
</tt>
-<sect1>show program (5)
+<P>
+Display the most recent WCY information that has been received by the system
+
+<sect1>show/wwv (0)
<P>
<tt>
-<bf>show/program</bf> Show the locations of all the included program modules
+<bf>show/wwv</bf> Show the last 10 WWV broadcasts<newline>
+<bf>show/wwv <n></bf> Show the last <n> WWV broadcasts
</tt>
<P>
-Show the name and location where every program module was load from. This
-is useful for checking where you think you have loaded a .pm file from.
+Display the most recent WWV information that has been received by the system
+
<sect1>shutdown (5)
Only the fields that are defined (in perl term) will be displayed.
+<sect1>sysop (0)
+
+<P>
+<tt>
+<bf>sysop</bf> Regain your privileges if you login remotely
+</tt>
+
+<P>
+The system automatically reduces your privilege level to that of a
+normal user if you login in remotely. This command allows you to
+regain your normal privilege level. It uses the normal system: five
+numbers are returned that are indexes into the character array that is
+your assigned password (see SET/PASSWORD). The indexes start from
+zero.
+
+You are expected to return a string which contains the characters
+required in the correct order. You may intersperse those characters
+with others to obscure your reply for any watchers. For example (and
+these values are for explanation :-):
+
+<verb>
+ password = 012345678901234567890123456789
+ > sysop
+ 22 10 15 17 3
+</verb>
+
+you type:-
+
+<verb>
+ aa2bbbb0ccc5ddd7xxx3n
+ or 2 0 5 7 3
+ or 20573
+</verb>
+
+They will all match. If there is no password you will still be offered
+numbers but nothing will happen when you input a string. Any match is
+case sensitive.
+
+<sect1>talk (0)
+
+<P>
+<tt>
+<bf>talk <callsign></bf> Enter talk mode with <callsign><newline>
+<bf>talk <callsign> <text></bf> Send a text message to <callsign><newline>
+<bf>talk <callsign> > <node_call> [<text>]</bf>
+Send a text message to <callsign> via <node_call>
+</tt>
+
+<P>
+Send a short message to any other station that is visible on the cluster
+system. You can send it to anyone you can see with a SHOW/CONFIGURATION
+command, they don't have to be connected locally.
+
+The second form of TALK is used when other cluster nodes are connected
+with restricted information. This usually means that they don't send
+the user information usually associated with logging on and off the cluster.
+
+If you know that G3JNB is likely to be present on GB7TLH, but you can only
+see GB7TLH in the SH/C list but with no users, then you would use the
+second form of the talk message.
+
+If you want to have a ragchew with someone you can leave the text message
+out and the system will go into 'Talk' mode. What this means is that a
+short message is sent to the recipient telling them that you are in a 'Talking'
+frame of mind and then you just type - everything you send will go to the
+station that you asked for.
+
+All the usual announcements, spots and so on will still come out on your
+terminal.
+
+If you want to do something (such as send a spot) you precede the normal
+command with a '/' character, eg:-
+
+<verb>
+ /DX 14001 G1TLH What's a B class licensee doing on 20m CW?
+ /HELP talk
+</verb>
+
+To leave talk mode type:
+
+<verb>
+ /EX
+</verb>
+
+<sect1>type (0)
+
+<P>
+<tt>
+<bf>type <filearea>/<name></bf> Look at a file in one of the fileareas
+</tt>
+
+<P>
+Type out the contents of a file in a filearea. So, for example, in
+filearea 'bulletins' you want to look at file 'arld051' you would
+enter:-
+
+<verb>
+ TYPE bulletins/arld051
+</verb>
+
+See also SHOW/FILES to see what fileareas are available and a
+list of content.
+
+<sect1>who (0)
+
+<P>
+<tt>
+<bf>who</bf> Show who is physically connected locally
+</tt>
+
+<P>
+This is a quick listing that shows which callsigns are connected and
+what sort of connection they have
+
+<sect1>wx (0)
+
+<P>
+<tt>
+<bf>wx <text></bf> Send a weather message to local users<newline>
+<bf>wx full <text> </bf> Send a weather message to all cluster users
+</tt>
+
+<P>
+Weather messages can sometimes be useful if you are experiencing an extreme
+that may indicate enhanced conditions
+
+<sect1>wx (enhanced for sysops) (5)
+
+<P>
+<tt>
+<bf>wx sysop <text></bf> Send a weather message to other clusters only
+</tt>
+
+<P>
+Send a weather message only to other cluster nodes and not to general users.
