Features

Contests and SO2R

Two independent software receivers, each with a sub-receiver: two HF bands at once and split in DX mode. With ExtCtrl the compact unit becomes a complete contest position.

Home shack and field

130 dB dynamic range on HF and 114 dB on VHF, 0.2 µV sensitivity and a +10 dB preamp keep you confident on a crowded band.

Field power

10–16 V on receive and 12–16 V on transmit: a switching supply or a battery will do.

2 m VHF and transverters

A built-in +22 dB VHF LNA and transverter support. With an external amplifier the PRO runs the whole set-up, and the kit stays portable.

Use Cases

  • 01

    Contesting

    Two independent receivers allow SO2R operation and hunting multipliers on the second VFO.

  • 02

    DX Hunting

    Wide panorama and instant split frequency jump give an edge in dense pileups.

  • 03

    Remote Operation

    Streaming audio and IQ over the network enables full remote operation worldwide.

  • 04

    Digital Modes (FT8/FT4)

    Direct integration with WSJT-X and loggers via TCI protocol with no virtual cables.

ExpertSDR3, TCI and ERS

Free ExpertSDR3 with free updates. The open TCI protocol connects loggers, skimmers and digital-mode programs without virtual COM ports or audio cables; programs without TCI use the RadioSync bridge (CAT, OmniRig). Expert Remote System (ERS) is included: control from a browser or ExpertSDR3, directly or through the ExpertCloud service.
