Radioddity GA-510 is a dual-band tri-power handheld radio based on a new generation chip with up to 10W of high power output. In addition, the GA-510 has many other useful functions such as dual-channel monitoring, VOX, voice prompt, and manual programming.

3 Ways of Scanning
GA-510 has three different scanning options (time scanning, carrier scanning, search scanning) for your use to meet various requirements.

Display Lowercase and Punctuation
Unlike other radios, GA-510 is completed with a bigger screen which can contain up to 10 characters long; letters (uppercase, lowercase), numbers, and punctuation are available.

SOS Alarm Function
Like no other analog radios, GA-510 comes with an SOS button at the top of the radio. You can activate the alarm by simply pressing and holding the orange button for 2 seconds. The alarm will go to other radios with the same frequency.

154 CTCSS / DCS
GA-510 supports CTCSS, DCS, and DTMF tones/codes. In the US, most repeaters require CTCSS/DCS for access, also allowing you to make group calls with a party, offering you more sub-channels for communication without interferences.
