    Poor frequency planning may also result in the mutual interface between the broadcasting stations. The inherent broad bandwidth of DB7000 re-broadcast receiver is vulnerable from stations working on the nearby frequencies, where signal strength will be the most important factor – the stronger the interfering station, the stronger the interference effect.
