MFJ-216 Instruction Manual                                         Deluxe Amplifier Saver

6

The MFJ-216 Deluxe Amplifier Saver can be used to activate the transmitter
with a pulsed signal of full peak power, without undue equipment heating. This
will allow you to move to the location of the device being interfered with, while
safely operating the transmitter at high power.

You can add filters, grounds, and move cables 

on the device being interfered

with

 without fear of overheating your transmitter. The short duty cycle also

reduces interference to other amateur operators.

Be sure to have a licensed operator attending your station, and to conform to all
FCC rules regarding CW emissions.
