1Overview
ELAD QSF-06 is a switchable preselector that allows the selection between 6 configurable filters. User
can configure the internal board by choosing the right set of filters within the filter module family
provided by ELAD or self-build. The QSF-06 board has also an on board active switch which ensure fast
commutation time between transmission and reception state and a band select output to drive an
external amplifier. Using the ELAD FDM-SW2 SDR software it is possible to configure the FDM-DUO to
automatically select the proper filter as a function of the tuning frequency.
The block diagram here below represents the QSF-06 board.

To install a new filter it is necessary to open the QSF-06 enclosure. To do that, first remove the two
standoffs of the DB9 connector present on the front panel.
Then, remove the four screws of the rear panel.

Now it is possible to extract the printed circuit board together with the rear panel like shown in the
picture below.
Once extracted, insert the desired filters in the chosen positions. The filter modules have a polarized
connection, i.e. they cannot be inverted because their connectors have a different number of pin.
Al last, relocate the printed circuit board inside the enclosure and screw in the four screws and the two
standoffs.
