For example sending RPT2M to QRU (at least in the UK) will get the nearest 2M repeaters to your location, with the frequency and tone, in a format compatible with the tune function of some radios. So send a query and you have the nearby repeater objects on your map or described in text.
QRU servers display on your map with QRUcallsign and an Info Kiosk symbol.
To query a server to see which if any have objects within range of your station and what groups they hold, send INFO to QRU. Servers with objects in range will respond with a list of supported groups: de CALL-SSID:group(#) group(#)… Max O@Mmi/km where group isthe name of the group, # is the number of objects in the group within range of the querying station, O is the maximum number of objects sent in response to a query, and M is the default (soon) range configured for that QRU server.
Appending a distance to the query (in miles or kilometers based on individual QRU server settings) will override each server's default range setting. INFO 20000 for example will get a response from QRU servers worldwide.
Once you have determined which groups are available sending GROUP to QRU where GROUP is the name of the group, should get a server to respond with the objects it has local to you, subject to the maximum amount of objects limit set on the server and also the range from your station. Again appending a distance to the query will override the server's default distance, but will not override the max objects that the server will send.
QRU servers can also be queried directly. For servers with a low amount of objects per group they will respond with a list of objects, servers with a large amount of objects will respond with an error message listing the number of objects per group the server holds.
Servers will attempt to limit the number of objects sent in a combination of max objects and range.
Servers will send item as message objects where ever possible, in an attempt to avoid large amounts of objects showing and also to better pass through remote igates.
In order for QRU servers to most effectively provide local information to visitors, a set of common group names is necessary. The list below serves as a starting point for groups you may want to configure.
To enable access to the QRU server configuration, there must first be at least one object created, within a query group folder (queryable groups start with a ? in the local configuration).
Object creation is done via the configure/objects menu.
To configure an object move the map until the location is centred on the map, it very useful to have crosshairs enable for this (configure/screen/crosshairs) and zoom in as appropriate. Remember to enable and set an interval and the vias. If you only want the objects to go out as a result of a query make sure the interval is set to 0, otherwise they will be sent on the scheduled interval also.
When you are centred, create the object via the configure/objects/create menu, you will get a popup menu. Enter a unique name, comment and select a symbol.
The difference with QRU is that created objects must be within a group beginning with ? such as ?HOSP. Once the group is created with the first object, the group will be available from the drop down box. QRU settings will be available under configure/objects after the first queryable group is created, it will be greyed out until then.
sets the limit to the amount of objects that will go out to a direct query to your callsign. If you have more objects in a group than this, a message will be sent with the total number of objects, but not the objects themselves.
This option sets the amount of objects to be sent per QRU request it works to an extent with the range option.
Objects within range of the querying station will be sent up to the max objects setting, querying stations can override the range setting at which point max objects will be sent.
Object dup checking and warning if other object created.
