Feature: 1. Programmable: Open sources firmware is built in IDE, allowing experimentation, new function can be added, contributions can be shared via for Github, and the software complexity is 2000 lines 2. Multi Band Support: The transceiver is continuously adjustment in the frequency range of 160m to 10m, loss of 20khz performance 3. Full Mode Support: The radio transceiver supports full mode, which supports USB, LSB, CW, AM, FM DSP modes 4. Circuit Simplification: The transceiver simplifies the original qcx circuit, reduces installation components by 50%, does not require complex transformer winding and alignment procedures, and is more versatile 5. Long Last Durability: The transceiver uses IRF series transmitter and aluminum alloy housing, has long last durability Specification: Item Type: Shortwave Radio Transceiver Material: Aluminum alloy Battery: 18650 lithium battery 5000mAh (built in) Usage: Radio reception Basic Parameter: MDS Receiver Noise Level: -135dbm (200hz BW) at 28mhz Blocking Dynamic Range: 123db at 20khz offset, 78db at 2khz offset.
