Re: Narrow filter for CW #ubitxcw

I'm using the tiny SOTABEAMS CW filter board. It is switched so that I can have it out for SSB and in for CW. It has two widths: 300 Hz and 1000 Hz. As a bonus it will also light an LED as a tuning indicator for those of us that are pretty tone deaf. Not bad for $30 + $5.79 shipping to USA.
