I have a feeling the 900 Mhz head sets may be hard wired form the order board

mike to a speaker back inside, at the window. The headset would only be for
the clerk to
talk to the order board and the antenna for this may be inside at the order
window also.

They may be using other frequencies than what you programmed in.
