Eighosee 5W UsDX SDR QRP Transceiver QCX-SSB to SSB 3-Band All Mode High Frequency Transceiver with Handheld Microphone

1.Open-Source : The USDX transceiver features a usdx open-source design, enhanced with personal touches like a front-end audio amplifier TDA1308, allowing for direct volume control with a knob rather than the less convenient menu-based adjustment. 3.Versatile Antenna Base: The all mode high frequency transceiver is designed with a variable antenna mount, providing the flexibility to install either an SMA seat or a BNC elbow seat, catering to different user preferences and connection needs. 2.Superior Power Conversion: For its power supply, the all mode hf transceiver employs a high-end LT1805 component for the 12V to 5V conversion, ensuring the rear circuitry is free from the risk of current deficiency and overheating that plagues common 7805 voltage regulators. 4.Enhanced Volume Control: The integration of a TDA1308 audio amplifier allows for a more tactile and responsive volume adjustment through a physical knob, this radio transceiver offering a significant improvement over the old menu-based volume setting. 5.Heat Damage Prevention: By utilizing the robust LT1805 for voltage conversion, the high frequency transceiver circumvents the high heat damage associated with standard 7805 voltage regulators, ensuring a and more sturdy operation.
