If there is a significant signal loss with the 250 hz. filters, there is something wrong.

  Hello, i am curious anyone has experience on topband with the new roofing filter from Inrad for the FT1000(D) series.
  I decided to upgrade my old FT1000 (see also the w8ji site) and keep it for more years. Also i am not using  the Ft1000 250 hz
  filters because of to much signal loss..      Change into 400hz filters worthwhile ?

  Greetings,

  Bert  PA7MM
