4O3A 1A2R Radio Switches
The 4O3A 1A2R Radio Switch is engineered to allow a single amplifier to be safely shared between two radios, making it an ideal solution for SO2R (Single Operator Two Radios) contesting or multi-radio station setups. It uses a "first PTT wins" logic, ensuring that only one radio can access the amplifier at a time, preventing signal conflicts and potential equipment damage. Each radio's PTT control can be independently disabled via a dedicated switch, offering added flexibility during operation. Once installed, the switch eliminates the need for manual rewiring—your amplifier remains permanently connected and ready. In the event of a failure during SO2R operation, the amplifier can be quickly reassigned from Radio B to Radio A, providing a reliable backup path.

ACOM 2S1 Automatic Two-Transceiver Commutators
ACOM 2S1 Automatic Two-Transceiver Commutators are transmit/receive switches that allow two transceivers to use a common load, which can be either an amplifier or an antenna. These ingenious devices guard each transceiver's input while the other transceiver transmits, they prevent simultaneous transmissions and they allow simultaneous reception. Especially useful for SO2R operations, ACOM 2S1 Commutators are specially designed to work in unison with the ACOM2000A automatic HF Linear Amplifier. Nevertheless, they may be used to commutate a multi-band antenna, or may be adapted for other systems, too. Operation of 2S1 switches can be fully automatic with full break-in (QSK) mode standard. Built-in protection grounds one transceiver RF input while the other transceiver transmits. Simultaneous transmission is prevented while T/R sequencing and RF relay contacts are electronically monitored continuously. Here are the specifications of ACOM 2S1 Automatic Two-Transceiver Commutators: *Frequency Coverage: 1.8-54MHz, all Amateur bands. *Power Handling: 200W PEP or continuous carrier. *Input and Output Impedance: 50 Ohm nominal, unbalanced, UHF female (SO239) connectors * VSWR: Below 1.1:1 from 1.8-54MHz; below 1.2:1 up to 80MHz. *Power Requirement: 11-14 Vdc, less than 30mA consumption. *Dimensions, WHD: 4-11/32 x 2-21/32 x 1-21/32 in. (110 x 67 x 42 mm) *Weight: 0.8 lbs. (350g) including cables *Operating Temperature Range: 32 - 122 degrees F (0-50 degrees C) Join the realm of advanced dual-radio DXing and SO2R contesting operations. Adapt an ACOM 2S1 Automatic Two-Transceiver Commutator to your system. Order yours from DX Engineering.

4O3A Switchable 3:1 Coaxial Power Splitter/Combiners
4O3A Switchable 3:1 Coaxial Power Splitter/Combiners can be used to split power between one, two, or three antennas/directions, or to combine two or three antennas. They are broadband, and capable of operating from 1.8–30MHz, with excellent matching and a well-designed PCB and circuitry. The PS-3000RX can be controlled using Station Genius or any manual switch controller that provides +12VDC for antenna selection. The SPLIT relay inserts a 50-to-22-Ohm transformer for matching when using two or three antennas.

ACOM A3x2000A HF Power Splitter/Combiner
The ACOM A3x2000A HF Power Splitter/Combiner is a passive device designed to sum the outputs of three HF linear amplifiers into a common load while the amplifiers are driven by a single exciter. This allows for better signal processing, modular amplification setup, and more consistent power levels. For best results we recommend three automatic amplifiers of the type ACOM2000A. Manual tune amplifiers with a precise tuning indicator like ACOM1200, ACOM1000, ACOM1010 or ACOM1011 can be used. Models that use a broadband input network are recommended. An automatic protection circuit is implemented in the ACOM A3x2000A, which monitors the three amplifier outputs during operation. In case of an imbalance, the protection circuit cuts the drive to the amplifiers and switches transceiver output to an internal 50 Ohm dummy load. The imbalance power is swamped by powerful resistors until the protection trips. Circuit reset is accomplished by a simple push-button. Specifications: * Frequency coverage: 1.8 – 30 MHz, continuous * Power output: 5 kW PEP, VSWR < 1.3:1 * Input impedance: 50 ohm unbalanced, UHF, SO-239 connectors, broadband * 8.268 in. wide, 12.795 in. deep, 7.677 in. tall * 14.1 lbs.
