Hi,
 
* It is advisable to have PC92 enabled, in particular:
set/var $DXProt::pc92_ad_enabled = 1
set/var $DXProt::pc92c_ipaddr_enable = 1
Although it may not always be feasible, it would be beneficial to encourage our CCC neighbor nodes to enable PC92, even in a limited form. This can significantly help when network-related issues arise.
 
* It is also recommended to periodically review the neighboring nodes we currently have configured. Some nodes may change, disappear, or stop responding, yet we may continue sending requests to them indefinitely.
 
* Keeping the node software up to date is essential, as many network-related issues are resolved in newer versions.
 
* Please note that the RBN servers SK0MMR and SK1MMR are not typical DXSpider nodes. They must be explicitly defined as RBN nodes, for example:
set/rbn SK0MMR
set/rbn SK1MMR

Finally, some examples of failed connections between nodes include:
Conn: number of connections
Disc: number of disconnections
