Description
Overview
GAOTek shortwave radio transceiver is a 5 W portable QRP model with SDR structure. Its core is based on 16 bit-CODEC sampling and has excellent performance. The newly added AM broadcast reception capability allows you to listen to news broadcasts from around the world; the 800 Hz narrowband CW digital filter makes transmission easier and clearer. Its circuits have been redesigned to improve performance, reliability and stability. The front panel buttons have been adjusted and the display improved to improve the user experience. An interface option for the XPA 125B 100 watt amplifier has been added, and the serial port connector has been changed to a 0.14 in ( 3.5 mm) socket to simplify connection with a personal computer. As an entry-level SDR portable, G1M (SDR version) will provide you with as many new technology experiences as possible.
