MFJ-382 AMPLIFIED SPEAKER

The MFJ-382 Amplified Speaker is good for QRP operators who want
to use speaker operation and HT users on 2 meter and 440 MHz for
more volume. It is small and rugged and uses a 1 2VDC power sup ply
but can be used just about anywhere because of the optional internal
9VDC battery connection. The unit is driven by a TDA7052A low
voltage power amp and has 1 watt output maximum with 36 dB gain.

Battery Installation

First, remove the two side screws from the cover. Slowly remove the
cover with caution to ensure avoiding breaking the speaker wires.
