RS1.RELAY

Remote Power and PTT Switching

Turning things off and on again, from ten thousand kilometres away.

What it is

A bank of relays under the site Pi's control, switching mains and low-voltage loads: radio power, amplifier, rotator, the QRM eliminator, and PTT lines. It is the module that makes a remote station recoverable instead of a trip, because the single most effective remote fix in existence is a power cycle.

Driven from a small terminal tool on the site Pi as well as from the web, and the terminal tool colours the state — green for on, red for off — because a list of relay names with the word OFF somewhere in it is exactly the kind of thing a tired operator misreads at two in the morning.
