DX Cluster Tidbits

Connection

If you are using a straight Telnet program, connect to w9bg.com 7373.

If you are connecting with a program that has a “cluster” application, edit the connection script to read w9bg.com:7373.  Most of these embedded telnet programs want the colon format for specifying the port.

N1MM   Configure > Hardware > Telnet Cluster > Edit

VE7CC   Configure > Telnet Cluster, edit or add entry

Make it talk

Programs such as VE7CC’s require that you send the command SET/DX_ARPC ON. The command line is at the bottom of the screen.

N1MM requires you sent the command SET/DX/OUTPUT ON .

One of those two should work with other programs including Telnet if needed.

Wow

The output at busy times is overwhelming to say the least. You must decide what it is you want output to your screen then enter one continuous set/dx/filter command. The options are listed on AB5K.net in the V6 User Manual.

For day to day DX watching with VE7CC I find that set/dx/filter cty<>k and not skimdupe works well. That gives me only DX call outs and eliminates sending me duplicate skimmer (RBN) spots. VE7CC and N1MM allow you to look at the band of interest.

N1MM

TELNET   When you enter a command using Telnet, incoming information keeps writing on your screen. You ignore that and keep typing your command and hit enter.

Ted has found that set/dx/filter (cty<>k and spottercty=k) or (call=K9IMM and spottercty<>k) * (Sub your call in for K9IMM.) works well with N1MM in DX contests.

Let me repeat that the filter command is a single entry, ie, all criteria must be stated in one command. Simply, this is because any newly entered command overwrites any previous entry. More information is in the V6 User Guide on AB5K.net. Here’s part of the manual concerening showing what can be filtered.

Set DX Filter

The Set/DX/Filter command is used to set the filters for the real-time and playback of past DX spots. A empty “set dx filter” command clears the filter. The “Set DX Mode Debug” command can be used to test complex filters to insure they are working correctly.

Examples:

set dx filter

set dx filter SpotterCont=na

set/dx/filter SpotterCty=k

set/dx/filter Spotterstate=tx or Spotterstate=ok or Spotterstate=nm

The fields available for the DX Filter and Show/DX commands are listed in the following table.

    Can it be made to show the lotw indicator? They need to put the show commands back the way they were.
