HYT TC-620

Hand Portable Two Way Radio
  • Professional 2 Way Radio
  • Durable and Reliable 
  • Voice Operated Transmit (Vox)
  • By simple pressing one button, users can switch to low power when communicating within limited range coverage or switch to high power when further distance is required. High transmit power optimizes range coverage while low transmit power conserves battery consumption, all at the user’s control.
  • The feature enables flexibility and easy migration of channel spacing requirements when the need arises, with no need to buy new radios.
  • Allows users to monitor the activity on the current channel. The feature is especially helpful for receiving a weak signal.
  • The Battery Save feature is automatically activated once no activity on the channel and no operation performed, for extended operation time.
  • Recharge the battery should the battery level run low.
  • A channel already in use is not available to other users.
  • The feature allows for more efficient use of channels by limiting the amount of time of each transmission.
  • You are able to customize the features of each radio for each user.
  • Easily copy the features of one radio to another.
  • Set up workgroups/users with unique CDCSS/CTCSS to prevent unwanted conversations on the same frequency.
  • Helps minimize interference from undesired weak signals and helps weak signals be heard.
  • The channel scan feature enables the radio to continuously scan each channel in the scan list for activity. Simply press a side function button to activate scanning. When activity is detected on a channel the scan process will stop and you will hear the transmission.
  • Enjoy the convenience of hands-free operation when used with optional accessories.
