No but there is filters to consider to filter out out of band 
interference. Not sure if the filters are the entire 2.4 or select channels.

Splatter-happy cheap equipment and amps... hmmm... hadn't thought of that...
there is another reason for a spectrum analyzer...
Let's say I 'sniff the air' and see lots of out-of-band energy coming from
their unit... I am guessing there is an FCC rule that says 'fix it or unplug
it immediatly'?

Is the other company using any Teletronics amps?  I have had problems with
the Teletronics amps especially when combined with Linksys.  The Linksys
have some out of band and the Teletronics amps take that and amplify it.
Even more specifically I have had Teletronics amps on channel 1 make channel
11 completely unusable.  Email me offline if you want to talk more about
amps and agc.  Just a thought.

Man, this stuff just doesn't play well with others does it?

I just spent the evening risking West Nile virus exposure in the middle of
   

a
 

marina with my laptop hooked up to an aBO trying to get more than 200K
   

back
 

to my tower .7 miles away. The marina is infested with an incumbent WISP
   

on
 

ch.1 using Linksys equipment and an omni (to cover 180* of marina, duh).
During the middle of the day, with the marina empty of ch.1 users, my
   

client
 

on ch.11 gets well over 2Mbps. As more of the ch.1 users start to arrive
home and use the ch.1 system, my user on ch.11 sees a slowdown as well.
My client is using an 18bdi Maxrad panel to talk to my 16dbi sector less
than a mile away. I know the 18dbi panel is overkill signal-wise, but my
   

POP
 

is in the same general direction as the ch.1 POP and I am using the 18dbi
more for the confined beam angle than for the overall gain.
I guess this is more of a rant than anything else... I just don't get how
these devices (11b in general, not sB in particular) have so poor
   

rejection
 

as to allow ch.1 traffic to bleed over into ch.11 traffic. Anyone know a
good super-narrow bandpass filter design? I would love to have an inline
channel filter I could put on the antenna connector to knock down the
out-of-channel energy another 25db or so.
Guess I'll go turn my antennas sideways and see if that helps... grumble
grumble...
