It's pretty common for gear like that to generate trash in the HF 
spectrum -- both internal electronics and the switch-mode power supplies 
that almost everything uses.  I would make it a condition of anything 
you sign that their equipment will not generate that noise at a level 
that you can hear.

That's something that you need to get them to fix.  You're probably 
paying them enough for their "service." :)

If you decide to try it yourself, study k9yc.com/RFI-Ham.pdf  The 
techniques described there will help with the trash that's radiated by 
the cables, but it won't do anything about what's radiated directly by 
the equipment due to poor design.
