800Frequency Transmissions only on Search Mode

I receive transmissions on 800 Frequency when in "Search" Mode but when I switch to the bank that has many of the same 800 Frequencies programmed into my R/S Pro 96..... I get nothing period.



Also when I lock in 155.56500 for OnslowCounty Sheriff dispatch (418) for over an hour....to listen to any NTBPD activiity... many times I hear absolutely nothing.



I live on the beach in NTB. Late at night it sometimes comes in when Scanner is in Bdrm on street side.



Is something wrong with my scanner or is it my location? Very frustrating. Any thoughts would be appreciated. Thanks.
