HF Band pass filters

You only need these IF you will have another TX operating nearby either in contest, field day, some multi-op station or SO2R.

I was asked about these and the ones I use in the shack that I built into some small metal boxes were based on K4VX design here:

They cover 160, 80, 40, 20, 15 and 10m

I do not have filters to cover WARC bands but I might make up some based on the W3NGN ones.


at some point.

I have to finish a K2 build first.
