I did the following - make a rule to both log and drop it:

iptables -N LOG_DROP
iptables -A LOG_DROP -j LOG --log-prefix "INPUT:DROP: " --log-level 6
iptables -A LOG_DROP -j DROP
iptables -I INPUT -s 47.88.219.0/24 -j LOG_DROP

then make those rules persistent:

sudo apt install iptables-persistent

OR if this package was already installed:

iptables-save > /etc/iptables/rules.v4

You can check on the attempts by:

dmesg | grep INPUT:DROP | tail -10

and adjust the number at the end for the number of line items you'd like listed; 10 fits within the admin console window.

My tags are selected for most casual users to be able to do something with it - I don't like TOO many tags up there, just the once likely to get some attention. Most of those FSK stations are encrypted and doing things like TDoA on them wasn't something I saw many folks do. For the few stations you can do something with, they are already on the dropdowns for the FSK/NAVTEX extensions and they decode fine. I will go and add the NAVTEX from Boston though.

To your point 6 - Mine are here: https://github.com/ringof/kiwi-dx.json

A couple things. One is that on Firefox, the spacing of the checkboxes is a bit off. Second is that the saved file name could use a timestamp added to it.

I'm going to leave this running for a while.
