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 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.

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.
Hardware Evolution
Gen6.0
Description of changes:
Optimized RF circuitry from the DAC to the power amplifier, resulting in a significant reduction in harmonic levels;
Upgraded 6M low-pass filter, resulting in additional harmonic suppression;
Upgraded 2M low-pass filter, resulting in a significant reduction in power loss;
Increased sensitivity of microphone inputs Mic1 by 4.2 times, Mic2 by 2.13 times;
Output power at the DAC OUT connector increased from +4 dBm to +9 dBm;
Optimized the VHF amplifier's BIAS node to improve stability.
