Download Manual

     This compact CB transceiver incorporates state-of-the-art microelectronics into a sophisticated Euro-styled 2-way radio. The superior engineering of the PRO510XL will treat your ears to professional 2-way radio communications as you've never heard it before.

"I have been selling these (510 and 520) for over a decade and I can still say they are one of the best ever made in the small size class. These radios last a very long time without fail."

  • ANL Switch
  • Compact Size
  • Full 40 Channel Operation
  • S/RF Meter
  • MOSFET Final Transistor.
  • Requires a High impedance electret microphone or amplified microphone.  These do not work well with the noise cancelling mics like the 636L or the RK-56

1. ANL Switch - You can select the Automatic Noise Limiter to help
reduce harsh background noise caused by a variety of interference sources.

2. TX LED - An LED lights to indicate when the radio is transmitting.

3. S/RF Meter - This LED meter shows the relative strength of the received signal or the RF output.

4. Channel Indicator - Displays the channel currently in use.

5. Channel Selector - This switch selects the desired channel for transmission and reception.

6. Squelch - The squelch control is used to eliminate background noise during the absence of a transmission.

7. Volume Control - Rotate clockwise to turn the radio on and to increase the volume.

8. Microphone Jack - The operational mode of the CB is controlled by the push-to-talk switch on the microphone.

Antenna Connector - This female connector permits connection of the transmission line cable male connector (PL-259) to the transceiver.

EXT SP Jack - An External 8 Ohm 7-Watt Speaker may be connected to this jack. The internal speaker is disabled when you plug into this jack.
