I have seen a few "FREDs" around over the years. None of them had
even a faint resemblance to any of the others. I even built a few
myself.<br>
<br>
FRED is a very versatile and variable species. In my experience,
the most spectacular was a pneumatically operated binary clock
controlled by a FRED which changed time every x seconds by opening
and closing a series of Venetian blinds - all done with air operated
pistons. The whole system took up the area of the average house
block, and was to be photographed by glider pilots from and altitude
of 3,300 feet before starting a race to give them a correct starting
time from a common clock (FRED). It was designed and built by a
very enterprising farmer. These days it's all done with a GPS
logger in each aircraft. <br>
<br>
Some would say some of my APRS systems resemble a FRED. I would
take that as a compliment.<br>

FRED was interesting in that it used just 292khz separation. I
don't

remember the exact history but when 2m FM started up in Sydney
the

primary channel was 146.000MHz, known as Ch B.

Dare I ask what FRED stands for?

We use a similar term at work ending in Ridiculous Electronic
