The N0HI (ex. K1KAA) AR-Cluster node went online in May 2008.  Since then, it has run 24/7 and is available worldwide via telnet.  The program is AR-Cluster by AB5K.  To connect, go to start-->run-->type "telnet cluster.n0hi.net".  You will then be prompted for your callsign.  Some newer versions of Windows do not have the telnet client turned on; go to the default program list on your control panel and enable it.

If you are using an older version of N1MM logger, you will need to add my node to the list.  Under "Configure telnet address, ports, etc." go to the tab with the COM ports.  At the bottom, next to the drop-down list, click the "edit" button.  In the callsign column, enter "N0HI" and in the address column, enter "cluster.n0hi.net".

This node propagates the same spots as can be found on many other nodes.  We have a connection to the backbone, as well as several passive connections to other local and worldwide nodes.  Some spots are also pulled directly from DXSummit.  During big contest weekends (CQWW, ARRL DX), you may find access limited, so connect early.

Helpful Commands:

  • Send a spot in the raw telnet stream: type "DX Frequency DXcall comment" (i.e. "DX 21200.0 DX1XXX loud")
  • Send a local announcement to all node users: type "ANNOUNCE MESSAGE (i.e. "ANNOUNCE DX1XXX qsl to N0HI")
  • Send an announcement to all users: local and global, use ANNOUNCE/FULL
  • See band-specific spots: type "SH/DX/time band" (i.e. "SH/DX/30 15" to see all DX in the past 30 minutes on 15 meters).
  • See local users: type "SH/USERS".
  • Talk to another user: type "TALK Callsign Message" (i.e. "TALK N0HI Hi Mike").
  • Callsign lookup (database may be old): type "SH/HAM Callsign" (i.e. "SH/HAM N0HI").

Cluster Etiquette

  • Please do not self-spot.  This is illegal in several contests and considered bad practice anytime.
  • Only send an announcement when it is necessary and pertinent; never include political views or the like.
  • The cluster is NOT a place to tell the DX to listen up, or that he needs to beam EU, or that he has a bad wrist etc. etc.
  • Please be careful about spotting; make sure you have the DX callsign correct to save everyone time and energy.
  • Remember the Amateur's Code.
  • If you are causing trouble, you may be blocked from this node and many other nodes.  None of us like to do it, but we will if you make us!

Interpreting the Raw Stream:

 

N1MM Telnet connection in multi-user mode:

Instead of connecting all of your stations in a multi setup using different SSID's, you can turn on N1MM logger's multi-user mode.  Name your stations and set the correct IP address for each.  Then, connect to a node on "Station 0".  Station 0 will pipe the telnet stream into all of the other stations.  This way, XX1XXX-1, XX1XXX-2, XX1XXX-3, etc. etc. don't all have to be connected.  Your bandmaps will still import spots the same.

About the Physical Node:

The physical hardware is a Dell P4 rack-mount running off a redundant battery backup.  No 2m radio is currently hooked up, but the TNC is a PK232.  The last radio used was a Kenwood TR-7930.

Connections at N0HI:

This is here for anyone who needs to get a hold of me for any reason.  The node callsign is N0HI, but you can usually find me connected as N0HI-1.  I use this during contests and otherwise to keep an eye on the node.  If you want to heckle the operators, all of the stations here are connected as N0HI-2 (see the N1MM multi-user mode trick above).  You may also see N0HI-3; these are usually upstairs or operators' computers.  If you send a message to N0HI, it will go to N0HI-1, N0HI-2, N0HI-3, etc.

Support:

This node is run completely at my own expense.  I do not require a user fee (even for frequent users) and I do not actively solicit donations.  However, if you would like to see newer and more improved features, consider making a donation.  Contact me for more information.
