Feature: 1. MULTI FUNCTIONAL CONFIGURATION: This QRP SSB CW shortwave transceiver features a 1602 screen, built in battery, charger, built in microphone, and speakers. The transceiver can be connected to an automatic button. Also perform CW decoding. 2. USDR uSDX: A compact 8 band SSB CW QRP transceiver. Built in lithium battery, built in microphone, PTT button, and extremely low RX current consumption, making it a good partner for SOTA, for POTA, or any other portable activities. 3. FINE WORKMAHSHIP: Aluminum laser shell marking, all aluminum buttons, with 4 translucent silicone buttons. 4. EASY TO INSTALL: The original qcx circuit is greatly simplified, with a 50% reduction in installed components. No need for complex transformer windings. No wiring program required. 5. EASY CARRYING: This multifunctional transceiver is light in weight and compact in size that can be used for different scenes.

Continuously adjustable in the frequency range of 160m-10m (20khz performance loss). 99 MHz 8. Open source firmware with built in IDE; Allow experimentation, add new features, share contributions through for GitHub, software complexity: 2000 lines of code 9. V based software can be used for fast and complete malicious operations (qsk and semi qsk), or to assist execution in digital mode (without CAT or PTT interface), for RX TX switches, with TX PA delay control external PTT output, simple installation and modification, 8 component changes, and 8 lines 10. Lightweight, low cost transceiver: Thanks to the for EER electronic liquid level transmitter, it has high power efficiency (without the need for a huge heat sink) and a simple design (without the need for complex balanced linear power amplifiers) 11. The phase of the SSB transmitter is entirely based on digital and software: controlling the phase of the si5351 PLL (through small I2C frequency changes exceeding 800kbit/s) and amplitude PA (through PWM to PWM) to test the microphone input and reconstruct the SSB signal. Button shaping circuit PA) 13. Three switchable analog controllers, independent of the front receivers 0db, -13db, -20db, -33db, -53db, -60db, and -73db 14. MDS receiver noise level: -135dbm (200Hz bandwidth) at 28MHz 15. Pre receiver selectivity: steep frequency adjustment -45dB/ten fold roll down+/-2kHz x blocking dynamic range: 20kHz offset 123db, 2kHz offset 78db 16. CW decoder, directly, iambic a, b keying Vfo a b and rit and frequency division, and switching corresponding relays with filters through for i2c Cat support (for TS480 subset), can transmit sound, keystrokes, and display text through for CAT .
