LNA-RLY box updated

Waiting a couple of new antennas from Goran (www.antennas-amplifiers.com), I took time in order to restore the LNA took repaired from Kuhne during the Friedrichshafen Hamfair.

So now the LNA-Relay box is updated with two different power lines: one for the relays and one for LNA.

This allow me to turn on or off as I like the LNA; with the LNA “on” the 12V is still controlled from the sequencer box but I can deactivate the LNA if I need/want.

A second relay is NC to a Dummy Load in order to avoid any hypothetical power return during QRO on the LNA input.
