Setup and testing
Now you are ready to set up and test your amplifier. Follow the steps below.
If you have any problems, refer to our troubleshooting section.
❒
1. Plug your kit into a 12V power source with the switch on your LPA1
turned off (click it until it is in the “out” position). You should not see the
LED light up.
❒
2. Turn on the switch. The LED should light up and stay on.
❒
3. Turn on a (preferably portable) receiver to the same frequency as the
transmitter. You may need to transmit to make sure that the two units
are working properly.
❒
4. Plug the output of your transmitter into J3, the input jack. Plug your
antenna cable into J2, the output jack. Turn on the switch again. You
should be able to receive the transmitted signal. You are probably too
close to notice any increased power difference, so you may want to
move the receiver away from the transmitter and try to see how far it will
transmit. With such great amplification, the LPA1 should increase your
transmitting distance several times, and you may find yourself going far
away from your house!
That’s all that you need to do to test it out. You may now use your LPA1 for
it’s intended purpose. You do not need to do anything else to use it because
you have just set it up during testing.
Troubleshooting
PROBLEM: The LED does not light when I turn it on.
SOLUTION: Even if the LED doesn't work, your amplifier may. First
measure the voltage on the leg or R5 closest to the switch. If it does not
measure near 12V, you have a problem with the power supply, power jack or
the switch is not on. You may also have soldered a topside connection
where you shouldn’t have. Check to be sure that D1 is installed the correct
way (flat side towards switch).
PROBLEM: The LED comes on, but the amplifier is not working.
SOLUTION: Make sure that the MAV3 and Q2 are installed properly. The
dot on the MAV3 should point towards C8. The “M” on Q2 should point
towards C6. Next, check the placement and orientation of all parts. You
may also have incorrectly soldered a topside connection where you shouldn’t
have. A good place to check would be the topside connections of the jacks
themselves.
