The DX Patrol QO-100 Down Converter is a high-stability receiver designed for precise and reliable monitoring of the QO-100 (Es’hail-2) narrowband transponder. Compact and efficient, it provides excellent frequency accuracy, gain control, and signal clarity straight out of the box. The latest “Blue” model, issued after 20 October 2019, supports four selectable intermediate frequencies—28.550 MHz, 144.550 MHz, 432.550 MHz, and 1296.550 MHz—allowing seamless integration with a wide range of amateur transceivers.
Each unit is supplied with a ready-modified LNB, pre-tuned for the lower QO-100 beacon frequency, ensuring strong and clear reception from the start. The converter includes an internal 10 MHz TCXO reference with 0.5 ppm stability, providing exceptional frequency precision. For even higher accuracy, it can accept an external 10 MHz GPSDO input. A PLL lock LED gives clear visual confirmation of stable operation, while the internal 12 dB preamplifier and adjustable RX gain help optimise signal levels for your setup.
Built with an aluminium enclosure for durability and excellent shielding, the DX Patrol Down Converter includes SMA connectors for IF output and external reference input, F-type connectors for LNB and TV cable compatibility, and a DC power input with ground shield connection. With its straightforward, PC-free operation and outstanding performance, it is the perfect companion for anyone seeking dependable, high-quality reception from QO-100.
