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 s=
uperiority. We are effectively at 24 hours daylight so Dx on MF and LF is s=
parser than winter...

Ive had a project to clear which has been with me for 4 years and that is t=
o 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 :-)

Shows 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-es=
sentials.  The system is now live and I can tell you my general reception o=
f 'mains" borne conduction QRM is lower=2C 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 re=
al terms the insertion losses are going to be respectable.

Just thought Id share
