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.
