I have a radio station coming over all 7261 sets when on a call. It is on all lines for the system as well as all the sets. It is not heard on telephone lines at the demarc on my test set.
Can anyone help?

Just curious but what happens when you disconnect your MOH source?

Are you by any chance sitting next to an AM radio transmitter. I had an EXEC-xe system at an AM radio station, had to do a lot of stuff to get rid of the station on the phones, then they installed a Nortel Norstar along with the XE when they bought another station and moved it into the same building. Never did manage to get rid of all the sound on the Nortel, then about 2 years ago, ripped it all out, installed an FX-II, and had a few phones I had to deal with, but for the most part was pretty music-free.

It is an AM station. I've had the system working for a year trouble free. This started about 1 month ago. Nothing changes if I remove MOH.
Powered down as well no difference. Looking to find the old RF Collars that used to go on the DXP station cables.

FYI - Worked with Vertical. They seem to thing there is a bad ground out on the telephone company pole.

I'd like to know how this works out for you. Keep us posted.

Might be interesting to see where the induction is happening. Possibly rig up a shielded line cord for a phone. Maybe try a length of shielded for the trunk lines, too.
