DX Engineering Key Line Combiner
DX Engineering Key Line Combiner – DXE-3RIGKEYLINE is another handy gadget that can take the ground-on-transmit amplifier keying lines from up to three transceivers or other devices and connect them to one amplifier or accessory. All four connectors are female RCA phono. After we came out with the DXE-KEYLINE-3 for one radio to key an amp and two other accessories, then the requests for this DXE-3RIGKEYLINE combiner came in. It really isn't surprising that many hams have multiple transceivers but only one amplifier. So, while a coax switch handles the RF, now the DXE-3RIG-KEYLINE handles the PTT keying from three radios to one amplifier. We also have a two-input, two-output combiner-splitter DXE-KEYLINE-DUAL, if that fills your needs. Each keying input of this device is guarded with a separate 45V 2A Schottky diode, providing ground-on-transmit isolation between each rig keying line. Therefore, this combiner will keep the load or voltage of any one device from affecting the others. This device is passive, meaning that it requires no power to function. It is not a transistor buffer and it has no relays. The DX Engineering Transceiver Key Line Combiner DXE-3RIGKEYLINE allows two or three ground-on-transmit keying lines inputs to key this unit's single output. It's another handy device that can be used in lots of ham shacks and it's a great gift item for the Amateur Radio operator who has everything… except one of these gems!

DX Engineering Transceiver Key Line Splitter
DX Engineering Transceiver Key Line Splitter – a handy gadget designed to be connected to the 'Ground-On-Transmit' amplifier keying line of a transceiver. This single-input, triple-output passive DC only unit provides multiple PTT keying lines, two for other accessories in addition to one for the amplifier. All four connectors are female RCA phono. Many special Amateur Radio devices, from receive accessories to simple phasing units and even automatic antenna switches, need to use the same T/R keying line as your amplifier. But they don't have a keying line pass-through for the amplifier. The Transceiver Key Line Splitter is that handy item that is needed in almost every shack! It's a great gift item for the ham who has everything! Developed by Ed, K8IV, you can think of it as an "IV" line for your radio's amp keying output, allowing more than just an amplifier to switch when your transceiver goes to transmit. Each keying output of this device is guarded with a separate 45V 2A Schottky diode, providing ground-on-transmit isolation between each accessory keying line. Therefore, this splitter will keep the load or voltage of any one device from affecting the others. But, the KEYLINE-3 input depends upon the voltage and current rating of your transceiver's transistor or relay keying circuit for an amplifier, so check your manual for the total that it will safely handle. Most accessory keying lines send 13.8 Vdc at only a few milliamps, so this combination typically works without issue. The KEYLINE-3 is passive, meaning that it requires no power to function. It is not a transistor buffer and it has no relays. We really want to call it the "Key Line 3.14" - (key line pi). You know… three outputs from one input with a total of four phono female connectors. But we can't call it a "pie" because someone might think they are buying some kind of non-raspberry micro-PC or something! No, it's just a splitter. So, here's the DX Engineering Transceiver Key Line Splitter with ground-on transmit for each port. Get your slice today!

DX Engineering Key Line Combiner-Splitter
DX Engineering Key Line Combiner-Splitter – DXE-KEYLINE-DUAL is yet another handy gadget that can take two ground-on-transmit amplifier keying lines from up to two transceivers or other devices and connect them to two amplifiers or accessories. All four connectors are female RCA phono. After we came out with the DXE-KEYLINE-3 for one radio to key an amp and two other accessories, then the requests for the DXE-3RIGKEYLINE Combiner and this DXE-KEYLINE-DUAL two-rig to two amp combiner-splitter came in. It really isn't surprising; some hams have two radios and two amplifiers or an amp and an accessory that both need to be keyed. While a couple of coax switches can handle the RF, now the DXE-KEYLINE-DUAL handles the PTT keying from two radios going to two amplifiers or to one amp and one accessory. Each keying input and output of this device is guarded with a separate 45V 2A Schottky diode, providing ground-on-transmit isolation between each keying input and output line. Therefore, this combiner-splitter will keep the load or voltage of any one device from affecting the others. This device is passive, meaning that it requires no power to function. It is not a transistor buffer and it has no relays. The DX Engineering Transceiver Key Line Combiner-Splitter DXE-KEYLINE-DUAL allows two ground-on-transmit keying lines inputs to key this unit's two outputs. It's another handy device that can be used in lots of ham shacks and it's a great gift item for the Amateur Radio operator who has everything… except one of these gems!

DX Engineering Transceiver Amplifier Keying Cables
DX Engineering Transceiver Amplifier Keying Cables connect the "ground on transmit" or contact closure provided by the radio that is required to make an HF amplifier switch from "receive mode" to "transmit and amplify mode" when using PTT (push-to-talk), VOX or break-in CW keying. DX Engineering Transceiver Amplifier Keying Cables are made for specific transceiver models that have special DIN or mini-DIN connector accessory ports which provide the transceiver's only connections for linear amplifier keying. One type of amplifier keying cable has one RCA phono plug for the amplifier relay jack, which is all that is needed. When the transceiver PTT (push-to-talk) is keyed, the RCA plug center pin is connected to the shield (and chassis ground in most cases) to key the amp relay or its solid state keying circuit. Instead of a direct connection to the amp relay, the RCA plug may be connected to the keying input of an accessory device (DXE-KEYLINE-3, DXE-RTR-2 or DXE-NCC-2), amplifier keying interface (DXE-SV-KR or legacy Ameritron ARB-704 or KD9SV Products SV-KR) or other amp keying line interrupt device, such as a meter or an array controller. Each has a keying input and a keying output for the amplifier relay or another accessory. Another type of amplifier keying cable has two RCA phono plugs, one RED plug for the amplifier relay jack and one WHITE plug for ALC (Automatic Level Control) voltage from the amplifier. The legacy ALC connection does not need to be used with present era solid state transceivers and most modern amplifiers. ALC was required for use on transmitters with tube finals. Some modern amplifiers do not have an ALC output connector. If the amplifier does not have ALC it is okay to leave the WHITE plug disconnected. Order your DX Engineering Transceiver Amplifier Keying Cables to connect to your transceiver accessory port for keying amplifiers, sequencers, receive-transmit interfaces, buffer relays, and other accessories. NOTE: To enable the function of this keying cable, some late model Kenwood transceivers require menu activation of the amplifier keying circuit.

DX Engineering Pretuned Quarter-Wave Phased Array Cables are ready to go into your phased array for 80 or 40 meters. These RG-11U coaxial cable assemblies are electronically tuned during production to 3650 kHz and 7100 kHz, the two most popular phased array frequencies. Pretuned Quarter-Wave Phased Array Cables ensure optimum pattern control and gain from your phased antenna array. They are available individually, in pairs and in four-packs, all terminated with soldered silver-plated PL-259s. These cable assemblies are exactly as required for many 80 and 40 meters phased arrays including Comtek Hybrid Four Square Arrays, DX Engineering TFS4 Four Square Arrays, as well as DX Engineering Dual Vertical Arrays. DX Engineering Pretuned Quarter-Wave Phased Array Cables are made from the highest quality waterproof PE jacketed, direct-burial RG-11/U 75-ohm low-loss foam coaxial cable. They are called "phasing feed-lines" because they are one quarter wavelength long electrically, which differs from the free-space dimension by the velocity factor of the cable. This RG-11U coaxial cable is manufactured to DX Engineering specifications, with a nominal velocity factor of 0.82. That means they're the right physical length to allow for easy burial and routing from the center-mounted array phasing unit to the base of each vertical element. Maximum performance is achieve with properly installed phased arrays, including ground-mounted base-fed full-size quarter-wave elements with free-space array dimensions and complete, interconnected ground radial wire systems. The electrical dimensions of phased array transmission cables are critical to system performance. Each of our cable assemblies is hand crafted and electronically tuned at DX Engineering. Eliminate the trouble and concern of trying to tune your own cables and order a set of DX Engineering Pretuned Quarter-Wave Phased Array Cables. NOTE: Custom tuned phased cables for all other frequencies in each Amateur band are also available. See DX Engineering Phased Array Quarter Wave Tuned Cables.

DX Engineering Transceiver to Amplifier Interface Cables
DX Engineering Transceiver to Amplifier Interface Cables support automatic band changing using band data, TTL or serial data, and are used to connect specific amplifier models to many modern transceivers. These cables have specially wired connectors to provide transceiver frequency information or general band data to the amplifier for automatic band changing. Most do not have a PTT amplifier keying line. Cables must be selected by amplifier model and transceiver brand and model: DXE-OMAUTO-RS232 connects OM Power Automatic Tuning Amplifiers to transceivers with RS-232C CAT or COM ports, including Yaesu, TenTec, Elecraft and Kenwood (FlexRadio requires additional serial USB adapter). DXE-2000 series cables are only for the Acom 2000A models DXE-ACOMSS series cables are only for Acom Solid State 2020S, 1200S, 700S, 500S and legacy 600S (replacing original DXE-600 series cables). DXE-ACOMSS-101, DXE-ACOMSS-YSU10 and DXE-ACOMSS-YSU8 cables carry PTT keying as well as Band Data, but they do not support Acom 04AT, 06AT or 20AT Tuner automatic operations, which require DXE-ACOMSS-YSU. Most interface cables carry only CI-V, CAT or COM frequency data, but not transceiver PTT to amplifier keying signal (ground on transmit). Automatic band-changing amplifiers that are interfaced with frequency data cables require a separate keying line. These have either a special connector to a male RCA, or are a standard male RCA phono patch cable, to handle PTT keying from the transceiver.
