19 dollar high pass filter

No more AM broadcast stations blowing out my front end. 19 bux on amazon, 15m build and made designed by a US HAM.

That looks extremely impressive yet I have no idea what I'm looking at.....

In a nutshell, There are some powerful AM stations that would come through no matter what band or mode I was using. So for instance, I would be trying to contact Australia, but would hear a local football broadcast on AM radio.

This filter basically removes the AM broadcast from the feed line and only allows the HF band that I am trying to use.

Ahh, understood. My only experience with filters was with my car stereo. I installed a filter to get rid of "alternator whine".
