Re: Hi-Per-mite CW filter

Hello Tim
It’s a narrow audio filter for CW.
I think it narrows down to 200 Hz?
It will work with any radio since it’s filter the audio output.

We have one that is wider for SSB, but I’m not finished kitting these yet.
Happy Holidays Tim

After a long delay which I apologize for, the Hiper Mite CW filter is back on the shelf.

Here is the link for the order page.

Thanks, 72
