In addition to the jumpers, the RX filter has three tunable inductors, L1, L2 and L3. Their
functions are as follows:
L2 controls the balance of the filter (flat response at both sides of center frequency).
L1 controls the attenuation at the upper side of center frequency.
L3 controls the attenuation at the lower side of center frequency.

The RX Connection Board is used in place of the RX Filter in applications that do not require an
RX Filter.
