Re: Forty-9er BCI Filter


 

There are photos of a BCI filter that should work with the Forty-9er posted on this site along with the values. It will be less expensive to make, since the CQ article is for 100W and uses hand-wound toroids. The parts are:

2 ? 1500pF ceramic caps
2 ? ? 560pF ? ? ? ? ? ?"
2 ? ? ?1.8uH inductor, axial lead
1 ? ? ?1.5uH ? ? ? ? ? ?"

The inductors and capacitors can all be purchased from Tayda Electronics (http://www.taydaelectronics.com/) for about a dime each. Connect it between the BNC and antenna connector on the Forty-9er. The insertion loss is about 0.04dB, so you won't even know its there. Take a look at the photos.

Jack,

Is there a schematic/parts list available for the BCI filter available yet, or are you waiting for the article to appear in CQ? (which month??)?? I just let my subscription expire and will have to renew or pick one up at the local parts house tomorrow if the is in the current month??? I am experiencing some minor BCI with the 49er.
