<div>We recently finished a six week after school STEM (science,
technology, engineering, and math) series on radio.</div>
<div><br>
</div>
<div>The kids got on the air via the WINS system and the local
KC7DMF repeater (thanks Mark), and on HF via a SOTA field setup.
They marked off on their US maps as the contacts came rolling
in.</div>
<div><br>
</div>
<div>Highlight of the series was building their own AM crystal
receivers. The kids worked together winding and tapping the
coils, and adding the resistor, diode, capacitor and high Z
earpiece. You should have seen the huge eyes as they clipped
the antenna lead to the locker banks and local stations came
booming in. Every single one of their sets worked the first time
and they all took home a working receiver they had built
themselves!</div>
<div><br>
</div>
<div>The series was such a hit with the kids and parents that
we've been asked to come back for the next series starting in
April.</div>
<div><br>
</div>
<div>The kits we used are available from the midnight science /
xtal society website:</div>
