Content preview: Hello Paul, typo in my last reply, the Teflon co-ax to the LPF is about twelve inches long!! Sorry. As Jay says, it's not the ringing per se, but if the ringing peak goes over the fairly low headroom of the FET's..... That's why I am particular about viewing it in real time with a USB scope on the network. Antenna or other issues can see it rise pretty damned high, then, POP! :) If they had more headroom I'd be less concerned like Alan! But they are pretty cheap and if there are no issues work great.
