METHOD FOR TRANSITIONING FROM WIDE BAND TO NARROW BAND RADIOS

摘要

A method for transitioning from wide band to narrow band EOT and/or LCU radios includes providing an EOT radio and/or an LCU radio having at least one filter in a radio receiver section that determines receiver bandwidth. The at least one filter provides a usable bandwidth that allows wide band reception for transmissions having a modulation level of about 3.0 kHz. Next, the at least one filter is removed and replaced with at least one new filter that provides a usable bandwidth that allows reception for transmissions having a modulation level of either 2.5 kHz or 3.0 kHz. The receiver section with the at least one new filter is thereby configured to receive transmissions with minimal signal distortion and degradation in either a narrow band or a wide band environment.
