>>HP filters offer little rejection towards the top end of the AM broadcast band..... like 1200-1710 khz. <<
I built several HP filters with >40 db attenuation on 1.7 KHz based on QST, I don't remember the year 90's about it. But some good information here > https://www.qsl.net/wb5wpa/Filter/DesignAMBrickWall_08.pdf You can but a 200W HP at DXE, this filter is the best you can get and very well calibrated/built. https://www.dxengineering.com/parts/dlw-fl1718 73' N4IS JoseCarlos _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
