Cobra PX500 BC Pro Business Radio REVIEW

Even though mobile phones have permeated the communication device market there is still a call for a portable radio — a.k.a walkie talkie. I’ve been in positions where there were so many people that mobile phones just weren’t reliable because systems were clogged due to overuse. Therefore, having a portable radio available can be very beneficial. The Cobra PX500 BC business radio is ideal for moderate use within a certain radius of a specified area.



  • UHF/FM: Ultra-clear long distance reception.
  • 121 Privacy Code: 38 CTCSS (Continuous Tone Coded Squelch System) codes and 83 DCS (Digitally Coded Squelch) codes provide a total of 121 privacy codes. 2662 privacy combinations are possible when the 22 channels are combined with the 121 privacy codes.
  • VOX (Voice Activated Transmission): 5 VOX sensitivity levels allow the user to select at which point the radio will detect their voice.
  • Call Alert: Provides an easily recognizable alert for incoming calls.
  • Roger Beep Tone: Confirmation tone indicates the completion of the user’s transmission, and signals others it is clear to talk.
  • Key Lock: When activated, provides key pad security eliminating accidental channel changes.
  • Power Saver: A unique circuit extends the life of your batteries. If there are no transmissions within 10 seconds, the unit will automatically switch to battery save mode.
  • Auto Squelch: Automatically shuts off weak transmissions or unwanted noise due to terrain or range constraints.
  • LCD Display: Easy to view display provides the radio’s status at a glance.


Set-up and use of the radios are very simple. You actually only have to unscrew the battery door, insert the battery (provided), connect the battery wire, and then replace the battery door. At this point, the charging station only has to be plugged into a wall outlet and the walkie-talkies placed in the charging cradle. This is one of the features I appreciate the most about these radios — the fact that they are rechargeable.

There are 22 channels to choose from and both radios have to be on the same channel in order to communicate with each other. It’s important to note that channels 8–14 are designated as ‘low’ power output while the others are ‘high’. This can be problematic for the range so if you are trying to communicate with someone a farther distance away, make sure you’re on one of the other channels.
