Up here in Alaska I can finally announce Spring is here as the
last of the snow melted in the garden today and 812 squadron Mosquito command
has air superiority. We are effectively at 24 hours daylight so Dx on MF and
LF is sparser than winter...
Ive had a project to clear which has been
with me for 4 years and that is to clean up the incoming and outgoing 2 phase
AC mains connection to reduce the conducted noise into the house wiring and
what ever I do here is fairly 'blocked" to some extent to the outside world -
ie the NSA snooping on my AC supply :-)
http://kl7uk.com/Corcom.jpgShows the ongoing
installation of 2 x (up to) 3 phase 200A Corcom filters - one for my emergency
100A board (with Gen bypass) and the other for non-essentials. The
system is now live and I can tell you my general reception of 'mains" borne
conduction QRM is lower, but I have some work to quantify the overall results.
Its not perfect as I do have a little 'C and L" as Im using the same input and
output Galv pipe for all the conductors but in real terms the insertion losses
are going to be respectable.
Just thought Id share
