[Dxspider-support] User filter command to hide digital modes (FT4/FT8) and RTTY

[Rudy Bakalov]

 I have been raising the alarm for over a month- there is something or someone that is converting skimmer spots into PC61 traffic. The spots look as if they come over RBN, but in fact they come from other nodes.
Why do we care:1/ These spots cannot be filtered out with the regular skimmer commands as they are not skimmer spots2/ If the something or someone starts dumping the entire RBN traffic, clusters that don't have the ability to scale will crash. The recent floods were child play compared to dumping of millions of RBN spots into the cluster network.

Hello group!

I have a user requesting to filter out all spots related to FT4, FT8, and RTTY.
This is the filter I found for him:

set/noskimmer
rej/spot 0 on all/data

However, I’m not sure if this also covers RTTY.
Can anyone shed some light on this?

73, HB9DHG Fulvio
