Recently, we upgraded customer from a small nortel sysem to a PACS R8. The customer was not happy because they could hear their CB traffic coming over two of their extensions loud and clear.
We pulled in new Cat 5e wire to no avail. We also installed filters (3-35 Mhz range), that we ordered from Sandman and installed them on both the handsets and mounting cords on the two extensions having this problem; still no joy. Customer stated that they did not have this problem with their nortel system.
Finally out of frustration, we recalled way back when...the first Merlin systems that recommeneded encasing the entire control unit with chicken wire and grounding it to clear transient radio interference. (What a way to impress customers with their new system...anyway I digress).
Capitalizing on this idea, we also recalled how the Merlin II power supplies had a copper foil to prevent induction of noise in the system. We couldn't find anyone who manufactured such a foil, so we stuck some aluminum foil with an adhesive to hold the foil to the R8 processor and grounded it. Voila! Great success! The CB traffic was knocked down to barely a whisper. Result, customer was happy with the result and we got paid for our trouble. Anyone have a similar experience? How did you solve the problem? Thank you in advance.

I've had radio station's picked up on Partner Sets, but it was the set itself acting as a transmitter, not the pbx. I noticed when I moved the phone out of line-of-site from the window, the music dissapeared. The customer just moved their phone to the other side of their desk.

Did you say you wrapped the Processor in foil or the power cord?
 
By the way, my client was a Nortel to a Partner as well. No issue with the Nortel and the phone in the line-of-site of the window.
 
Thanks for your reply Telecomboy. The 509 R8 was screwed to the wall as normal, but what we did was attach the aluminum foil to the surface that was exposed, but not blocking the vented portion of the unit.
