Description
The AT-5555N II is an upgraded version of the AT-5555N, featuring CTCSS/DCS and NRC. The TX and RX noise reduction can effectively filter out background noise, such as car engine sounds and music. Different levels can be set according to various signal strengths.
The radio has a high power output (PEP) with 60 W for AM, 45 W for FM, and 60 W for SSB. It supports FM, AM, USB, LSB, and PA modes, with a frequency range of 28.000 to 29.699 MHz.
The big LCD display shows the frequency and a range of other information.
The radio also features a flexible menu function and PC program software. You can download the free software from the AnyTone official website.
