[SADXA] 40m DAY DX of a Yagi vs K07SS CW Skimmer on a Dipole - Dec. 2nd

Tue Dec 3 20:47:23 EST 2019

I first set up either the VE7CC cluster (using the CC-User application) or the AR-Cluster (using commands I create and load into the N1MM Telnet window). I then point N1MM at either the AE5E-2 or VE7CC-1 nodes on the VE7CC cluster, or the NC7J node on the AR-Cluster. Either cluster does the same thing. The backbone of both clusters is the Reverse Beacon Network. I prefer the AR-Cluster.  

I request spots from only AZ and UT. I don't specifically ask to use any particular CW Skimmer (such as KO7SS) but will get spots from any AZ or UT skimmer. I want any and all spots from AZ & UT. 

I am only familiar with N1MM. Other programs that you may use can probably be pointed at either the VE7CC or AR-Cluster and will do the same thing as N1MM wrt displaying spots.

There are potentially ways to log into a particular CW Skimmer, but I do not do that. Most CW Skimmers feed the clusters anyway.

Let me know if you want more detail.

73, Bill K6WSC

How does one access the KO7SS
Skimmer ?
