Accessing State and Section Information in Clusters - n4af/TR4W GitHub Wiki

This page is to provide support information helpful in implementing full state multiplier support. The idea is that is the cluster provides state (and/or ARRl section info) in the spot record, we can use that in TR4W to guess if this is a multiplier for contests that use state as a mult. The same goes for contests that use ARRl section like SS. Of course, the station could be operating portable in another state or section, so if there is a valid mult in the spot comment, we let that override things.

Here is a summary of how to get the accessible information in various DX cluster servers.

#CC Cluster ##Enable State support CC Cluster requires the user to turn on state displays in the system so each spot will have the state info if there. The way to do this is to enter set/usstate

The state is at the end of the comment record. The state of the SPOTTER is at the end of the record after the timestamp.

#AR Cluster AR Cluster version 6 supports several very useful extensions. ##Enable State/Section Support To enable state and/or sections display, enter set dx extension state section. As this is only a version 6 command, you can also enter sh/version to check the version of the AR software. This will return,

In this reply, the state will always be first and then the section. This data is always added from position 30 and back int he spot. So if you only requested set dx state, the state record would be in positions 29 and 30. To process this data, it is important to look at position 30 and read backwards to detect a - or a + (the + indicates LOTW if the set dx extension lotw command is used).

My thought for the way this works is that when we see NFL in the example above (assuming NFL), we run this call through the possible mults and highlight it accordingly in the bandmap. This really would be a killer application in SS so you can just see the ones you need to work. We have that in DX Contacts based on country derived from the prefix or zone so why not state or section.
