DX Engineering ISO-PLUS Ethernet RF Filters
DX Engineering ISO-PLUS Ethernet RF Filters are very effective EMI Suppressors that are quickly and easily connected inline on Cat5e or Cat6 network cables. Their patented* design provides common mode RF interference and EMI noise filtering of radio frequencies from well below 1 MHz to 100 MHz and beyond. DX Engineering ISO-PLUS Ethernet RF Filters have no effect on throughput; Ethernet data signal levels and speed remain unchanged. *US Patent No. 11,211,679 B2 Electromagnetic interference (EMI), also known as RF interference (RFI), can be imposed onto your received radio and data signals from many electronic devices normally found around a residence, a radio room or a business network. Areas of major concern are the Gigabit Ethernet Cat5(e) and Cat6 cables used for network (LAN) connections between personal computers, printers, multi-port switches, cable modems, routers and radio transceivers, and between many other devices. DX Engineering ISO-PLUS RF filters, installed on both ends of Ethernet cables, work two ways. First, they can mitigate RF interference caused to the Ethernet connected device. Second, they can reduce interference to radio receivers and other Ethernet devices that is caused by RFI or EMI generated by an Ethernet connected device. ISO-PLUS filters are sold in pairs and are normally installed at each end of an Ethernet cable; one filter at the RJ-45 Ethernet plug of the first device and the other filter at the RJ-45 Ethernet plug of the second device. Each ISO-Plus comes with one six inch shielded RJ-45 patch cable (color may vary). They are designed to be installed in pairs; offered in a 2 filter package DXE-ISO-PLUS-2 or a 10 filter package DXE-ISO-PLUS-10. Click "More Details" below for additional information. DX Engineering ISO-PLUS Ethernet RF Filters are an important tool to improve productivity and radio reception of weak signals. "If you can't hear them, you can't work them."

DX Engineering Time Variable Sequencer Units
DX Engineering Time Variable Sequencer Units are microprocessor-based transmit/receive control signal-delay units. They can provide 0-30 milliseconds of delay, programmable in 2 milliseconds increments, to as many as five different outputs tied to your CW keying or push-to-talk (PTT) lines. By controlling the receive-to-transmit (and back) timing of linear amplifiers, and other sensitive equipment, damage caused by improper switch timing may be avoided. These DX Engineering TVSUs improve CW performance by eliminating the annoying leading-edge chopping or truncating of Morse characters, especially important in contests or pileups, where sending accuracy is critical. Now RoHS-compliant, they may also control external devices, such as preamps, active antennas, or external relays that need to have power removed during transmit. Separate power-in and power-out jacks on the front panel are used to control external power. Two 2.1mm power plugs and two 3.5mm stereo plugs are provided. Additional TVSU features include: * Control timing of PTT turn-on, hang delay of PTT, amplifier hang delay, external antenna relay hang delay, and turn-on delay of auxiliary output * Dip switch settable delays of 0-30ms in 2ms increments * Side tone generator that follows input of keyer or hand key, not transmitter * Side tone pitch can be programmed from 300 to 1,000 Hz in 50 Hz steps * Front panel headphone jack with adjustable volume * Supports CW full break-in * Can control external power to DX Engineering active receive antennas and thereby permit operation in closer proximity to transmit antennas Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. To make sure that all of your equipment keeps safely in step, use one of these DX Engineering Time Variable Sequencer Units!
