Topband: NCC-1 Phaser

Fri Jan 22 08:20:56 EST 2016

Thanks guys for all the input - no pun intended.

What I have been considering, is to install a 4 square receive system,
offset from my Bog's by 45 degrees.

The two systems could then be phased as needed, for interference redux, or
signal improvement.
