I have a commercial AP that is using a CM9 ath5k radio (evidently, I could be wrong)
and it has the ability to do a constant transmit of raw noise (RF probe shows
noise, but a monitor-port sniffer does not see any frames from the CM9).

I don't know the low-level details of how it is doing this, but I suspect
it is using something like madwifi for a driver.

Does anyone know how this can be done with modern software and
ath5k or ath9k NICs?

Hi Ben,

I wrote some code to do this on ath5k -- I can post a patch if you're
interested in using ath5k for this.

Here's a snapshot of what it looks like when running on ch.1:
