But it is if it's the link hearing the other signal.
Looks like that specific frequency is a very bad one for a link.
I know of at least one link on the frequency.

With all the unlicensed services used the same group of frequencies we 
use for links this is likely going to be an ever increasing problem. 
Wireless mikes, Wireless headsets on drive throughs, security, remote 
control, Weather stations,  RFID, etc...

Sounds like it'd be a great frequency for a beacon at the legal limit, 
but here the legal limit is 50W and Beacons are in a different part of 
the band anyway.<sigh>
