Subject: [RTTY] Skimmer spots dropped at VE7CC cluster node

These links may be interesting to some of you. These are the typical 
rejected spots of any CC Cluster.

RTTY skimmer spots are considered valid if spotted by ONE Skimmer. RTTY 
Skimmers are generally more accurate than CW and there are simply not enough 
of them to use 2 or more Skimmers to validate them. CW spots are valid if 
spotted by 2 or more Skimmers.

Here is the list of dropped Skimmer spots by the VE7CC-1 cluster.
If you connect to the RBN directly, you will receive all these spots as well 
as the good ones.

Many times there are two calls in succession that are dropped for RTTY 
calls. I am receiving data from both the RBN and DL4RCK for redundancy. 
Usually they both spot the same RTTY calls.

Most columns are self explanatory.

The number directly before a skimmer call is a quality number. It is the 
number of times a call has been detected as correct minus the number of 
times it is busted. When the number decreases below 5, it is no longer 
considered valid. If the active call has not been spotted in 12 minutes it 
is also no longer considered valid. In one place, for 9A1A the quality 
number is over 2000. This means 9A1A has been spotted over 2000 times on the 
same frequency!
"Sysop added" means I have manually added a call to the list because it is 
busted all the time and is never good.
