SuperBroom Plus TA – Operating Manual

Detect

Selects Detect Audio output, this modulates the transmitter

signal with an audio tone (approximately 1 KHz in

frequency). The tone will be heard as audio output via

returned harmonic signals from potential targets. This

function can be used in two ways.

1 Target Detection. If no target is detected random (white)

noise is heard through the loudspeaker or headphones. If a

target is nearby but its returned signal is weak the tone will

be heard, accompanied by noise. As the returned signal

increases the tone becomes clearer. Some users may prefer

to use this mode as a method of initial target detection and

later switching to Click mode to pinpoint the target.

2 Confi rmation. When a return signal is detected, to confi rm

the signal is a result of SuperBroom's transmission rather than

an interfering radio source the Detect function can be used

to listen for the audio tone. If the signal is from an interfering

source other audio sounds will be heard.

The right-hand column of buttons is used to select the signal

source.

Caution Operation in this un-license mode is the responsibility of

the user.

COMPARE

Selects the Compare function as the signal source for the

audio output and signal strength indicated on the antenna

head display. This function shows the difference between

the two harmonic returns (second harmonic signal strength

minus the third harmonic signal strength). Since the

comparative harmonic returns from electronic targets differ

signifi cantly from simple mechanical non-linear junctions

this provides powerful discrimination against false targets.

Note 1 Only the Click audio output setting can be used with this

function, and is automatically selected by SuperBroom.
