Playing with wireless I tried to use airodump-ng to see what one can get
out of it.
Command
/usr/local/sbin/airodump-ng -w xx ral0
works fine for ~30 minutes and then loses all stations.
Restarting this command gets it to the state with no stations right away.
But after I do 'ifconfig ral0 down ; ifconfig ral0 up' command works
again. Until it loses stations in ~30 minutes again and everything repeats.
It seems that ral0 gets into some internal state that prevents
airodump-ng from picking up packets. And down/up clears it.
But the output of 'ifconfig ral0' doesn't change after down/up:
ral0:

My card is recognized as: ral0: <Ralink Technology RT2561S> mem

And I use 7.0-STABLE.
This seems like a bug in the driver. But I am asking here hoping someone
will have an answer off the top of their head.
