Public address 

An external 8 ohms, 3 Watt speaker must be connected to the PA jack 
located on the rear panel when the transceiver is used as a public 
address system. The speaker should be directed away from the 
microphone to prevent acoustic feedback. Physical separation or 
isolation of the microphone and speaker is important when operating 
the PA at high output  levels.

INTRODUCTION 

This section explains the basic operating procedures for the DX 
2517 amateur base station transceiver. 

 

CONTROL & CONNECTIONS: 

1.

 POWER ON/OFF   CONTROL:

  Push ON to apply power to 

the unit. 

 
2. 

RF/SWR METER:

 This meter operates during transmit only. It 

reads power output or SWR. 

 

3. 

SWR/CAL SWITCH:

 This switch is used with the 

“CALIBRATE” pot (No.12) to measure your SWR. Simply put 
this switch in the “CAL” position. Then, transmit in AM, FM or 
CW while adjusting the “CALBRATE” pot 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 to reach the “SET” mark). 
Now, while still transmitting, put this switch up to the “SWR”
