	The RESULT of MY FILTER: DONE with his TESTBOARD, LOOK here... This filter is for the 60 meter band, and show a fine filter, with a perfect SWR, impedans, and -3 db bandwith, with less than -0.5 db RETURNLOSS, designet with ELSIE, a Simulation program.
	The TESTBOARD, mounted with components JUST works.
	In ELSIE, you can change the components to STANDARD values, and still se the resulting filter.   TRY IT FOR YOURSELF
