I don´t think that botserv send a notice to a channel, Locutus suggest make a loop.
You can save the name the channel in a var too.
and then

ON ^*:NOTICE:*:*:{
if (($me isop %thechansave) && ($nick == BotServ)) {
.window -n @BotServ 300 400 500 200
echo @botserv 12,0 $1-
write $mircdirong\bot.ong $2-
}
haltdef
}
