disabling RCON echo

[jimv2000]

Is there a way to keep the results of rcon commands from being broadcasted to all of the players? For example, if I do "rcon sv_gravity 400", everyone gets a message that says that gravity was changed.

Ideally, I would like admins to be the only ones to see these messages, but I'd setting for no one seeing them.

you could use/write some plugin that changes those cvars not to broadcast on change, but nobody will then be able to see it.

(actually it's a cvar property, not all rcon commands do this)
