SunSDR2 DX

A hundred watts on HF in a compact aluminium case.

100 W on HF, up to 80 W on 6 m and up to 8 W on 2 m, two independent software receivers, 2.6 kg including the cooler. Designed and built in Taganrog, supported directly by the engineers.

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.

Where it works

  • 01

    Home shack

    Full power without an external amplifier, tuning from the E-Coder2 panel instead of a mouse.

  • 02

    Contest position

    SO2R/SO2V, split in a dense pile-up, CW skimmer over TCI.

  • 03

    DX expeditions

    Full power in a compact case, from the tropics to the Arctic.

  • 04

    Digital modes

    Reliable operation through long FT8 transmit cycles.

  • 05

    VHF

    2 m on its own, the PA50WV amplifier, transverter support.

  • 06

    QO-100 satellites

    Hardware groundwork for full duplex and transverters.

Proven on DX expeditions

Dozens of expeditions over seven years, in harsh climates.

ExpertSDR3、TCI 和 ERS

ExpertSDR3 及其更新均免費。開放的 TCI 協定可連接日誌、Skimmer 和數位模式軟體,無需虛擬序列埠或音訊線纜;不支援 TCI 的軟體可透過 RadioSync 橋接(CAT、OmniRig)。隨附 Expert Remote System(ERS):可透過瀏覽器或 ExpertSDR3 進行控制,支援直連或透過 ExpertCloud 服務連接。
