1. Topband: 160M Bandpass filter drawing. K0FF (score: 1): Author: K0FF@ARRL.NET (K0FF); Date: Mon, 2 Oct 2000 13:23:35 -0500; Fred, here is a drawing for a 160M bandpass filter. The first section is a 5 element Chebyshev lowpass filter and the second section is a 7 element Chebyshev hipass filter. Different values are given; /archives//html/Topband/2000-10/msg00009.html (8,454 bytes)

K0FF (score: 1): Author: n7rt@flash.net (Hardy Landskov); Date: Sun, 01 Oct 2000 17:47:01 -0700; Hi All, I believe the intermods are being created in the toroids and hence have a spectrum that goes into the 160 band. In that case, a bandpass filter on the coax line going to the shack will do no; /archives//html/Topband/2000-10/msg00010.html (9,877 bytes)

K0FF (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Tue, 3 Oct 2000 10:15:18 -0400; Hi Earl, A notch would be my first reaction also, but the component values required are not commonly available when nulling 200 kHz. Also padding the trap to frequency would be a "chore". The most si; /archives//html/Topband/2000-10/msg00014.html (8,304 bytes)
