David, A Low Pass filter cutting off above 6m is useful here, because our not so local FM BC station operates just above 100 MHz.
I suggest that if you do convert a LPF, do not use small toroidal inductors (unless "air wound") if the filter is to be used between a receiver and an antenna feeder. Small cores can create IMD problems ftom BC stations etc, which is one reason why the solenoid type of inductor is used. 73, Geoff GM4ESD David Cutter wrote on Friday, June 18, 2010 9:27 AM: > I was idly wondering if I should convert them to something useful, perhaps > to a band pass filter.
