Re: uBITX AM BCI Filter (3.5mhz High Pass Filter) #ubitx

Hmmm, a stopband below 1705khz, passband above 1800khz.
Possible, and worth looking into for the few interested in operating on 160m.

But given the same number of parts, designing for a passband above 3.5mhz
will give much better results.

Nick, Just curious… there is a ham band that u cut out between 1.8-2.0 MHz with this filter.  I think the board is super but maybe start the band pass at 1.8?
