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.

KD9SV Products SV-DXSS DXpedition Receive Antenna Switches
KD9SV Products SV-DXSS DXpedition Receive Antenna Switches are the ultimate unit for the active low-band DXer. They combine their legendary Front End Saver with the 80/160 Variable-Gain Preamp, a Four-Position Receive Antenna Switch and a high-speed Solid State Amplifier Keying Interface, all into one easy-to-use package. Originally designed for DXpeditions, they are sure to be on the wish list of all low-band DXers! DXpedition Switches were built to be connected to transceivers that ARE equipped with receive outputs and inputs, and to the transceiver's amplifier keying line. DXpedition Receive Switches will directly key all late-model RF power amplifiers. They include a heavy-duty relay for receive antenna disconnection and transceiver RX ANT INPUT grounding, giving your transceiver the ultimate in front-end protection. The four-port antenna switch allows you to select from different receive antennas and the variable-gain control adjusts for 10 to 28 dB preamplification with dual-band band-pass filtering. This lets you choose, on the fly, the correct antenna and gain combination for optimal signal-to-noise for changing band propagation conditions. You may also bypass the unit when you are operating on the higher bands or to listen to the low band transmitting antenna. KD9SV DXpedition Receive Antenna Switches include the Front End Saver, with a lightning-fast solid-state amplifier keying system that is full break-in CW (QSK) capable for all modern amplifiers. They can handle legacy amplifier positive DC voltage keying lines up to 500 Vdc at 8 A. However, DXpedition keying circuits will not work with amplifiers that have negative DC voltage keying lines such as the Heathkit SB-200, Yaesu FL2100-B or Collins 30L-1. For these and other negative DC voltage keyed amplifiers, pair these DXpedition Switches with KD9SV Products SV-KR External Keying Relays. Whether you are a DXer, contester, antenna experimenter, or just want easy access to multiple receive antennas, KD9SV Products SV-DXSS DXpedition Receive Antenna Switches will organize your station as never before!

DX Engineering RT4500HD Rotator Control Extension Cables
DX Engineering RT4500HD Rotator Control Extension Cables are premium pre-assembled cables with the appropriate 4-pin mating connectors installed for the DX Engineering RT4500HD Rotator. They eliminate the time-consuming task of soldering two additional optional connectors onto a long control cable. Designed for durability, these 4-conductor cable assemblies are rugged, yet flexible and are built to last with heavy duty stranded copper conductors and industry leading direct-bury polyethylene (PE) black jacket that is impervious to water and highly resistant to sunlight UV. Two 12AWG wires are for DC supply to the rotator motor and two 18AWG wires are for the rotator Pulse Sensor. One end of the cable features an interlocking weather-sealed 4-pin DXE-LP20-F female connector that mates with the RT4500HD rotator pigtail male connector. The 4-pin DXE-LP20-M cable mount male connector on the opposite end of this extension cable is intended to be connected to the controller pigtail. The DXE-LP20-F Rotator Control Line cable-mount female connector supplied with the RT4500HD, along with any convenient length of DXE-CW1812OR Heavy-Duty Spec Rotator Cable (sold separately), can be used to make a permanent pigtail with appropriate ring terminals for the screw terminal connections on the rotator controller. The use of the pigtail and this Rotator Control Extension Cable with mating connectors supports easy disconnection of the controller for additional surge protection and for simplified equipment repositioning. In this arrangement, the female receptacle connectors are appropriately used to supply power. Cable mounted male connector exposed pins are never energized when they are disconnected from their mate, thereby eliminating an accidental short circuit to ground. NOTE: At the appropriate point along the run, this cable may be cut, split, prepared and terminated for connection to a grounded surge protection device. Control Line Surge Protection, such as the DXE-CLTB-M or DXE-IS-RCT, is recommended to be installed at the grounding point of the tower base.
