DXPatrol MK4 Wideband SDR Receivers
DXPatrol MK4 Wideband SDR Receivers are a compact, high performance wideband SDR receiver offering seamless coverage from 100kHz to 2GHz. With its built in HF up converter, precision band filters, and excellent strong signal handling, it delivers clean, reliable reception across the entire spectrum. Dual independent SMA antenna inputs let you connect optimized HF and VHF/UHF antennas simultaneously, while software selectable modes provide flexible tuning and fast spectrum sampling up to 3.2 MS/s. Housed in a rugged, shielded aluminum enclosure, the MK4 works effortlessly with popular SDR apps on Windows, Linux, Android, and iOS, enabling everything from aircraft ADS B tracking and NOAA satellite reception to amateur radio monitoring, RF analysis, and general RF exploration. Powerful, portable, and endlessly versatile—the DXPatrol MK4 opens the door to the full radio spectrum. Building upon its advanced wideband architecture, the DXPatrol MK4 delivers the same seamless 100 kHz–2 GHz coverage found in professional grade SDR platforms, far surpassing the performance of basic USB DVB T dongles. Its integrated HF up conversion stage and precision band filtering ensure excellent dynamic range, strong signal tolerance, and exceptionally clean reception across HF, VHF, and UHF bands. The independent SMA inputs for HF and VHF/UHF allow operators to connect multiple antennas connected without re cabling, while software controlled switching between direct sampling and Q signal sampling modes provides flexible, optimized performance across the entire spectrum. Supporting sampling rates up to 3.2 MS/s, the MK4 enables wide, instantaneous spectrum displays—from 96kHz to nearly 1MHz—depending on the SDR software in use. Fully compatible with virtually all RTL2832 based software, the MK4 performs flawlessly with applications such as HDSDR, SDR Radio, SDR Touch, GNU Radio, and others. It also supports specialized tools including dump1090 for ADS B aircraft tracking and programs designed for receiving NOAA weather satellites at 137MHz, making real time flight awareness and satellite image reception straightforward and reliable. Whether used for public safety monitoring, HF/VHF/UHF/ Amateur Radio listening, educational experimentation, or advanced RF signal analysis, the DXPatrol MK4 provides a powerful and flexible platform for exploring every corner of the radio spectrum. Setup is simple and efficient: users typically install the recommended Zadig USB driver rather than stock Windows drivers, and the receiver connects via a USB-A to USB-C cable (included) providing data and power to the MK4. Android operation is supported through SDR Touch when used with compatible OTG capable smartphones or tablets. The MK4's rugged, shielded aluminum enclosure houses a high performance preamplifier with excellent IP3 characteristics, robust front end protection, gold plated SMA connectors, and highly efficient band filters for clean audio and stable operation. With native support for Windows, Linux, Android, and iOS devices, the DXPatrol MK4 stands as a compact, durable, and exceptionally capable SDR solution for beginners, advanced experimenters, and serious RF hobbyists alike.

DXPatrol v3.0 GPS Disciplined Oscillators
DXPatrol v3.0 GPS Disciplined Oscillators (GPSDO) deliver laboratory grade frequency precision by disciplining a high quality OCXO with continuous GPS correction. Designed for applications where absolute accuracy and long term stability are essential, this third generation model provides exceptional performance in a compact, easy to deploy package. A GPSDO ensures its output never drifts over time, which is crucial for RF, timing, measurement, and synchronization tasks across both amateur and professional environments. Using a U Blox 7N GPS reference driving a 10MHz CTI OCXO (0.05 ppb* stability), the DXPatrol v3.0 generates up to four programmable independent LVCMOS outputs from 350kHz to 350MHz, giving engineers and radio operators the flexibility to feed multiple devices from a single, ultra stable source. The clear OLED display provides instant visualization of position, satellite lock status, and time information. Multi constellation support—GPS, GLONASS, and Galileo—ensures strong reception and rapid lock in under challenging conditions. For users who need highly accurate system time without relying on the Internet, the DXPatrol GPSDO v3.0 can act as a standalone precision time source. Operators can synchronize a PC directly to the GPSDO, making it ideal for isolated networks, secure installations, DXpeditions, remote stations, and any environment requiring dependable, offline timing for digital modes such as WSJT. Accessing the GPSDO is simple: scan the on screen QR code with a smartphone and instantly connect via Wi Fi to a built in configuration and status webpage. The unit operates from any 6–14VDC supply via a standard 5.5/2.5mm barrel connector, drawing 350mA during initial warm up and stabilizing at approximately 270mA. The DXPatrol GPSDO v3.0 is ideal for amateurs working with weak signal digital modes (FT8, WSPR, JT9), microwave and millimeter wave bands, SDR systems, and beacons, where even small frequency drift can degrade performance. Its stable 10MHz reference ensures precise tuning for high frequency transverters, consistent calibration for test equipment, and reliable synchronization in remote or Internet isolated stations. From EME enthusiasts to portable microwave rovers, the GPSDO v3.0 provides the rock solid frequency foundation advanced operators depend on.

DXPatrol v2.0 GPS Disciplined Oscillators
DXPatrol v2.0 GPS Disciplined Oscillators (GPSDO) deliver ultra stable 10 MHz performance engineered for demanding microwave and RF applications, now upgraded with even greater accuracy and reliability. Its high contrast OLED display provides real time satellite status, timing, and position data, powered by a fast acquiring multi constellation receiver supporting GPS, GLONASS, and Galileo. USB C power ensures simple, universal connectivity. The rear panel includes the GPS antenna input along with three ~7 dBm sine wave SMA outputs and one square wave SMA output, making the v2.0 ideal for reference distribution, SDR stabilization, test setups, and transverter chains. Operating in hot start mode, it maintains a precise 10 MHz output even without an active GPS lock. The internal OCXO (Oven Controlled Oscillator) reaches full stability after a brief warm up, providing exceptional long term accuracy. Perfect for amateur radio operators, the DXPatrol v2.0 excels in weak signal digital modes, microwave and millimeter wave operation, SDR accuracy, beacon work, and lab grade frequency standard applications—anywhere rock solid stability is essential.

DXPatrol Charon Adalm-Pluto HF Transverters
DXPatrol Charon Adalm-Pluto HF Transverters unlock the full potential of your ADALM Pluto SDR by expanding its frequency coverage far beyond the stock 325MHz–3800MHz range. The DXPatrol Charon HF Transverter bridges the gap, enabling true HF operation and giving experimenters access to the 160-6-meter amateur bands with an output power of 50mW—greatly expanding the Pluto's capabilities for research, learning, and on air experimentation. At the heart of the Charon is a stable 80MHz local oscillator, allowing clean and reliable frequency conversion into the HF spectrum. The built in VOX system automatically switches the unit into transmit mode, while a two color status LED clearly indicates RX or TX state. For operators who prefer manual control, a dedicated PTT jack input is also provided. Configuration is simple: the necessary parameters for transverter operation can be set directly in the ADALM Pluto software, and the displayed operating frequency remains accurate after conversion. Power is supplied through a standard 12–16VDC input, and the unit uses SMA (female) connectors for both antenna and Pluto RX/TX interfacing. The Charon HF Transverter is housed in a lightweight, 3D printed PLA enclosure, providing a compact and practical solution that integrates seamlessly into your SDR setup.
