Occasionally, you may wish to post something that does not fall into the normal parameters for a DX callout. You may wish to tell everybody connected that 10 FM is open for example, or ask if anyone knows the QSL manager for a certain callsign etc. You can do this using the ANNOUNCE command.
announce 10 FM is open in IO84NB to europe.
That would let everyone know locally that this was the case, however it would not be forwarded to other nodes connected. To send announcements to other connected nodes as well, you would use the FULL extension.
announce/full Anyone seen SV1AAW today?
It is also possible to send an announcement to a specific connected node. This announcement would be posted locally only to the node in question.
announce/pe0mar-11 How is the wx in Holland?
As well as the above, you can announce to a distribution list. These lists are dealt with under the "Mail" section. Let's say there is a list called SIX for 50 Mhz enthusiasts. You can announce to just the people who are on this list.
announce/six looks like the band is opening!
You can list previous announcements in the standard format with the SHOW command. As before you can list just the last 5 or as many as you wish upto a limit of 99.
