Flathagen made a 30m lowpass filter for his Softrock Ensemble RXTX tranceiver:

I just finished a 30m lowpass filter for the Softrock Ensemble RXTX tranceiver.  I used the schematic provided by WB5RVZ.  L200 and L201 is wound to about 0.9uH, whereas C200 and C202 is 100pF and C201 is 330pF. Everything is soldered to a PCB (ugly construction) and I added two switches and a coax to enable on and off switching of the filter.
