The decoder requires a stabilized
voltage source. WAVECOM recommends
the use of a somewhat larger than
necessary supply,
about 2 to 3 Ampere output.
The W 4010 decoder has an internal
fuse that protects not only against
overcurrent, but also against wrong
polarity.
1.2

RECEIVER CONNECTION

The W 4010 demodulator needs audio
from the receiver with a level of
about 0.1 Vpp, up to a maximum of 5
Vpp. Many receivers have line or
tape recorder outputs
fixed levels, and it is recommended
to use these because their outputs
are independent
control. The large AGC range of the
decoder permits
almost any receiver.
