Using A Separate Microphone
1
Install the 36” microphone into the microphone
connector on the transmitter.
2
Install the noodle antenna into the antenna connector
on the transmitter. Adjust length according to band of
operating frequencies.
3
Attach fresh batteries to the snap on connector.
4
Using a small screwdriver, turn the recessed rotary
switch located on the front cover to the desired
channel. The configuration of each channel is
managed with DTC programming software. The
programming software included with your Derringer
allows you to assign frequencies, and set the
deviation.
The NOODLE ANTENNA
The “noodle” antenna may be adjusted over the frequency
range of 138 MHz to 174 MHz by adjusting the amount of wire
that is folded back along side the end of the antenna. Use
heatshrink tubing to hold the adjusted length.
The total length may be calculated by the following formula.
Length (inches) = 2950 / (Freq MHz)
Example:
CH1: 150.000
CH2: 151.000
CH3: 152.000
Center of operating frequency
Length (inches) = 2950/151
Total length = 19.5"
Length
Loop
2950 151 = 19.5
