Switchable preselector filter board for FDM-DUO with active switch and band selection output. The internal filters are suitable for receive use only.
QSF-06 is a switchable preselector that allows selection among 6 configurable filters. The user can configure the preselector by choosing the filters to install from the set of filters supplied by ELAD.
