The evening's program was "How to Reduce Repeat TVf Complaints,"
given by W00GS (the carrot). After a visit from this bunch, would you
complain again?
Imagine the mutual interference when two
or more of these fish gatherl Fortunately,
these fish have developed a very sensitive
jam-avoidance system. Using electrical detectors
all along its body which compare signals
from its own electric organ with those from
nearby transmitters, the fish determines
whether the jamming signal is at a higher or
lower frequency than its own. When the fish
figure this out, the one with the higher frequency
rapidly moves up a few Hertz, and the
one with the lower frequency moves down a
few Hertz.
It's interesting to notethat these electric fish
automatically do as hams do-OSY off the
QRM. Perhaps the ham equipment manufacturers
or an enterprising home-brewer will
take a cue trom this curious creature!

Revisited
There are several updates and
corrections to the Unlden HR­
2510 modification article that appears
on pages 34-35 of the
April '89 issue. RadiO Shack discontinued
the OPDT DiP relay,
part #275-213A-replace it with the Potter and
Brumfield part IT85N110114-12. The reference
on page 35 conceming R39, a 2.2k resistor,
is Photo A instead of Photo D. Finally, in
the sentence following the last reference,
change " A1fR2/C1" to " RlIR2IC2."

Alabama hams taking part in Emergency
Net X-Ray won't soon forget the first weekend
of March. As severe weather pounded
the state, 170 hams spent over 30 hours handling
priority messages. While the weather
bureau issued scores of tornado warnings and
amateurs assisted with emergency communications
, two twisters struck a town just east of
Birmingham. Amateurs remained on duty at
the National Weather service until Sunday
evening. Good workl
NotJust Another
Fish Tale
A recen t Issue of the journal Natu'" describes
the wor1l of scientists at the SCripps
Oceanographic Institute In California on
the electric fish Eigenmannfa. These fish
emit electrical discharges in the 300-500 Hz
range from an organ on their tails, to detect
friend and foe.
Young Hams' Net
