Abstract
This work presents the measuring the field strength of Radio Vishnu 90.4cr along different routes with geographical location registrations. To determine the signal quality at different locations until we reach the null point and to know the things which we need to change in order to increase the signal quality. We used a field strength meter and there is no frequency selective network present in the field strength meter. In the due time, when we were trying to work with the field strength meter we found that the values we obtained are related to vector sum of the FM signals which are available in that particular location. So, we designed a band pass filter with high quality factor for sharp cut-off frequency of 90.4MHz. We have travelled along 7 directions, up until we obtain the Null point in all the Directions
