[Skimmertalk] Bad Skimmer Spots

[WB4MAK]

Lee et all,

I have always run in "aggressive" validation from the beginning but today
only switch back to "normal" based upon messages I read yesterday. 

I've now switched back to "aggressive" and I'll see if the accuracy
improves. Also, at least monthly I check calibration to the nearest hertz on
50 MHz to make sure the frequency is accurate.

As one of the skimmer server RBN sources using a QSR1 I would always welcome
feedback on errors and hopefully suggestions for improvement.

73,

Subject: [Skimmertalk] Bad Skimmer Spots

Here is a small subset of bad skimmer spots. I am looking at a full feed
from the RBN.  

These are only spots for USA calls that have not been issued.  Many times
the first letter of a call is missing.  Many of these are actually Italian
calls with the "I" missing.

I will update the list from time to time.

CC Clusters drop these bad calls.

There are many other non USA calls that are wrong which also have the first
letter missing. These are harder to find.

Other bad calls occur when the last letter is missing or truncated or is
added
+in error.

"E" and "T" seem to be the most often added bad letters.

Lee
