[Dxspider-support] rejecting digital modes on whole DXspider node (not client)

[dd5xx at web.de]

Hello all,
 
I am aware about the filtering possibilities on client side and I use them successfully. But my goal is: I want to create a secondary instance of DXspider running on my server (running on another dedicated port) which shows *ONLY* ssb and cw spots. It should reject all digital modes like ft8, rtty, jt, psk, etc. How can I configure my DXspider node to reject such incoming spots? I want my users connect to this dedicated DXspider node and receive only SSB+CW spots without the need to configure any local logbook software filtering or sending any DXcluster specific commands.
 
Any help appreciated. Thank you
Saki, DD5XX
