Heathkit HD-1250 - Neutralization; Use as a Relative Field-Strength Meter

Page 52
NEUTRALIZATION
1 . Remove the final voltage from the transmitter.
2. Apply power
to the driver stage.
3.
Use the Dip Meter in the absorption mode.
4. Couple
the dip meter coil
to the output of the
stage being neutralized.
5.
Adjust
the Dip Meter
to the driver frequency
to
obtain a maximum meter
deflection.
6. Adjust
the neutralizing
capacitor for
a
minimum
meter reading.
USE AS A RELATIVE
FIELD-STRENGTH METER
Refer
to
Figure
3-5
for
the following steps.
1. Connect
a short antenna around
the dip meter
pickup coil as shown.
2. Set the Dip Meter for
use in the
absorption mode.
3.
Tune
the Dip
Meter to the resonant
frequency of
the
transmitter
output.
4. Position the
pickup antenna
at various points
around the transmitting
antenna
to
determine
relative
strength.
