Transceiver and control panel

SunSDR2DX handles the radio signal; E-Coder2 puts everyday controls back in your hands. The bundle pairs a direct-sampling HF/VHF transceiver with a hardware panel for tuning and frequent commands.

The DX delivers 100 W on HF, up to 80 W on 6 m and 7 W on 2 m. Two independent software receivers let you monitor different parts of the bands.

Hands-on tuning

E-Coder2 uses a 1024 PPR optical tuning encoder. Three additional push encoders and 14 programmable buttons bring frequent commands out of the on-screen interface.

Assign controls in ExpertSDR settings. Templates cover 72 functions, so the panel can follow your own operating routine.

Audio and connections

Connect the transceiver to the computer over LAN and the panel over USB. E-Coder2 includes a 24-bit CS4272 audio codec with a 114 dB dynamic range.

Four rear 6.3 mm sockets accept headphones, a microphone, a CW key and a PTT footswitch. A dedicated CW core reduces sidetone latency when operating Morse code.

Features

100 W and a DDC/DUC architecture

  • Direct sampling on receive (DDC) and direct digital synthesis on transmit (DUC), with separate receive and transmit paths.
  • A 16-bit LTC2209 ADC at 160 MHz: real dynamic range for dense pile-ups and contests.
  • A quiet 140 × 140 mm fan and stable operation through long transmit cycles on digital modes.

Two independent receivers

  • Two software receivers, each with a sub-receiver; reception 0.1–65 and 95–155 MHz.
  • Panorama up to 312 kHz and a band scope up to 80 MHz.
  • Simultaneous reception on different HF bands, DX split and an SO2R position with peripherals controlled over ExtCtrl.

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.

About the software
  • ExpertSDR3Free software for operating on the air
  • TCIAn open protocol for loggers, skimmers and digital modes
  • ERSRemote operation from a browser or ExpertSDR3

Hardware headroom

  • ALC*

    Input for external power amplifiers; today control runs over ExtCtrl.

  • Full Duplex*

    Full-duplex operation.

  • Predistortion*

    Predistortion for a clean signal without external devices.

* The hardware is ready; software support is planned in ExpertSDR3 updates.
