QRO.cz RX AuditePRE SDR Antenna Switch Controllers
QRO.cz RX AuditePRE SDR Antenna Switch Controllers combine the functionality of a T/R switch, a receive antenna input and a receive splitter with specialized switching, all with RF limiter protection. The transmit/receive (TX/RX) main antenna can be shared with both outputs, transceiver and receiver (SDR) with RF power limiter protection. These versatile devices are perfect for use with a separate SDR receiver for Spectrum Panadapter, WebSDR or as a Skimmer Server to contribute spots to the Reverse Beacon Network (RBN). The RX-AuditePRE features frequency coverage of 100 kHz–60 MHz including 160 through 6 meters with a maximum transmit power handling of 200W and a switchable 16 dB preamplifier. Included in the Package: RX-AuditePre Switch – Assembled and Tested DC Cable – DC barrel connector to stripped and tinned wires

QRO.cz Stack Match High Power Broadband Antenna Phasing Switches
QRO.cz Stack Match High Power Broadband Antenna Phasing Switches are high-performance broadband antenna combiner designed to impedance match two Yagi antennas to a single transceiver (TRX). Ideal for mono-band, tri-band, or multi-band antenna systems, they support both in-phase (BiP) and out-of-phase (BoP) configurations, enabling advanced stacking and phasing configurations. Whether you're optimizing a contest station or enhancing DX performance, these Stack Match 1-2 switches allow seamless switching between upper, lower, BiP, and BoP modes. Built with high-quality components and housed in a rugged aluminum enclosure makes them a reliable choice for demanding HF operations.

QRO.cz MK2 Classic 6-to-2 Antenna Switches
QRO.cz MK2 Classic 6-to-2 Antenna Switches are engineered to optimize SO2R (Single Operator Two Radios) setups by offering flexible switching configurations. Operators can use the switch to connect two transceivers to up to six antennas, six transceivers to two antennas, or even configure it as a Band Pass Filter (BPF) switch for two transceivers. The MK2 version introduces several enhancements, including improved isolation and a newly integrated Hazard Protection Board for added safety and reliability. This model also incorporates First-Win logic, which ensures that only the first valid control signal is accepted, preventing conflicts. Control is made versatile with BCD (Binary-Coded Decimal) inputs that feature optocoupler isolation and high-voltage protection. The BCD interface is compatible with TTL logic and supports voltages up to 15VDC. Additionally, BCD signals exceeding 13VDC can directly power the internal relays. For added protection, when DC power is not present, all unused antenna ports are automatically grounded.
