Whenever there is a contest (especially RTTY), some bogus/bad RBN skimmer spots are coming through having no way to filter these out easily.
One thing that has been implemented on top of RBN skimmer spots, is either a “master.dta” filter, or waiting with spots until more skimmers post the same call on the same frequency - the CT1BOH method.
Also VE7CC cluster uses something like this.
Any opinions?
