The N2EME SDR Switch 0–70 MHz 100W is a premium RF switching solution for amateur radio operators seeking seamless integration of Software Defined Radios (SDRs) into their existing setups. Engineered for single-receive configurations, this switch allows your SDR to function as the primary receiver while maintaining full transmit capabilities on your HF, 50 MHz, or 70 MHz transceiver. Key Features: Frequency Range: 0–70 MHz Power Handling: Up to 100W Low Insertion Loss: Ensures minimal signal degradation High Isolation: Protects SDR and associated RX components during transmission Single RX Design: Ideal for setups where the SDR serves as the sole receiver Compact and Durable: Built with high-quality components for long-term reliability Operational Overview: Receive Mode (Default): Antenna signal routes directly to the SDR receiver, safeguarding all RX-only components. Transmit Mode: Upon PTT activation, the switch reroutes the transceiver's output to the antenna, isolating and protecting the SDR and RX chain. Why Choose the N2EME SDR Switch? Optimised for Weak Signal Work: Designed by VHF/EME operators to ensure optimal performance without compromising signal integrity. Enhanced Station Performance: By dedicating the SDR as the primary receiver, operators can leverage advanced features like panadapter displays and improved signal processing. Ease of Integration: Compatible with popular transceivers and SDRs, facilitating straightforward installation and operation.
