INTRODUCTION

This section explains the basic operating procedures for the DX
2527 amateur band base station transceiver.
CONTROL & CONNECTIONS:
1. POWER ON/OFF CONTROL: Push ON to apply power to
the unit.
2. MICROPHONE JACK: Used to connect microphone for voice
source.
3. RF POWER CONTROL: This control adjusts the RF power
output level.
4. CALIBRATE CONTROL: To check your SWR, simply rotate
this control while transmitting until the needle on the left meter
goes to the small red "notch" on the SWR scale. (You may need
to be at maximum power in AM, FM or CW to reach the "SET"

mark.) Then, while still transmitting, push the small white SWR
switch (number 11). This will give you an SWR reading. When
you are finished, be sure to turn the calibrate control. Fully CCW
to the "RF" position so you are able to read your RF output
power. You will hear the "RF" switch click on.
5. ECHO: This control is used to the amount of echo. This is a
switched pot that must be on along with switch number 6 for the
ECHO to operate.
6. ECHO/VOICE/ROBOT SWITCH: This switch selects between
the ECHO, VOICE CHANGER and ROBOT sound effects. In the
PHONE
ECHO position, the ECHO control pot must also be on. The
ECHO sound is controlled by the ECHO pot and the TIME pot. In
the VOICE position, the TIME pot controls the pitch of the voice.
22
In ROBOT 1, 2, 3 or 4 none of the sound are adjustable. They are
fixed. In order to have all sound effects off, turn this switch to
ECHO and turn the ECHO pot off.
7. TIME: This control sets the time delay of the ECHO repetitions
in the ECHO modes. In the VOICE CHANGER mode, this pot
controls the pitch of your voice. Fully left (CCW) raises the pitch
of your voice. Fully right (clockwise) lowers the pitch of your
voice.
8. TALK BACK: This is a switched pot that controls the volume of
the talkback sound. It does not affect the sound your transmitting.
You can turn the talkback off (Fully CCW) or adjust the volume
as you desire. This talkback circuit can be used anytime – even
without any sound effects. Please note that this particular main
PC board does not allow much of a talkback signal. Therefore,
even if you have this control up to maximum, the talkback will
not be very loud.
9. RF GAIN CONTROL: This control is used to reduce the gain of
the RF amplifier under strong signal conditions.
