Transceiver 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.
Control panel
The panel has a main tuning encoder with 1024 PPR resolution, 14 programmable buttons with templates for 72 functions, and 3 programmable rotary encoders with push-button functions. It connects via USB and supports macOS, Windows and Linux.
Audio and monitoring
E-Coder2 is the control panel of the new generation with an HQ built-in stereo 24-bit audio codec with 114 dB dynamic range (CS4272).
When you operate in RX mode, the ExpertSDR2/3 sends the same audio stream in the TRX and in the E-Coder2. Thus, you can listen to the air directly from the TRX or from the E-Coder2, the latency in both cases is the same - almost nonexistent. Also, in E-Coder2 we've implemented a special CW core to minimize latency if you monitor yourself during transmission.

Remote operation
E-Coder2 will be especially useful for those who use the Expert Remote System (ERS) and who place their transceiver at any distance from the operating position.
Connections and power
USB-port should provide 5V, current not less than 0.5 A. On the rear panel of the E-Coder2, you'll find four stereo Jack 6.3 connectors: headphones, microphone (designed for asymmetrical mics), CW-paddle, PTT foot switch.
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.
