Use with any HF rig

The XV transverters can be used with nearly any transceiver that covers the 28 to 30 MHz frequency range, including Elecraft's high-performance K3S, K3, K2. Single-port and dual-port IF connections work with almost any transceiver interface. IF transmit levels from -20 dBm to +39 dBm (.01 mW to 8 W) can be accommodated, with a constant-impedance IF termination for top performance. Reliable overload detection is included at the IF port to protect the mixer. Multiple transverters can be daisy-chained to a single IF transceiver, providing multi-band operation without cable rearrangement. A brightly-illuminated label clearly identifies which transverter is selected. There is also an auxiliary BNC connector on the rear panel that can be wired for a RX-only path at the XV output for split TX/RX antenna paths.

Easy to Build, Understand and Repair

Like Elecraft's transceivers, the XV Series transverters are completely modular, simplifying construction and alignment. The professionally-written, fully-illustrated manual will appeal to experienced as well as first-time builders. The kits are easy to assemble, featuring our "no-wires" construction, and all surface-mount parts used in the kit are preinstalled at the factory. Comprehensive Assembly and User Manual Our illustrated step-by-step assembly instructions include modular assembly and check out of each stage. Extensive theory of operation and troubleshooting sections are also provided.

      Q: Are the XV Series of transverters available as kits only?

      A: Yes.  However, we do have builders for hire.  Please contact for more details.

      Q: When should I consider adding the XVOVN, high stability oscillator oven?

      A: For maximum stability, consider adding the high stability oven for CW, SSB/phone or digital modes.  It will not be needed for FM operation.


      Q: Can the XV series of transverters be used with other radios than Elecraft?

      A:  Yes.  The XV series of transverters are quite flexible for connections to most any transceiver that can operate in the 10 Meter band.
