Switchable Preselector Filter Board for FDM devices.
SPF-08 is a switchable preselector board that allows selection between 8 configurable filters. User can configure the board by choosing the right set of filter within the filter module family provided by ELAD or self-build. Moreover, ELAD FDM-SW2 SDR software can be configured to automatically select the proper filter as a function of the tuning frequency.
SPF-08 includes a bypass but does not include any filters.
SPF-08 is compatible with FDM-S1, FDM-S2 and FDM-DUO.
