Description

Product Description
5-10W USDX USDR HF QRP Transceiver SSB/CW 8-Band +Microphone+Battery+Charger
Describe:
- Brand new and high quality
- Made of high quality materials, durable
- USDR/uSDX is a pocket-sized 8-band SSB/CW QRP transceiver. It is designed with built-in lithium battery, built-in microphone, PTT button and extremely low RX current consumption, it is a good partner for SOTA, POTA or any other portable activities.
- This QRP SSB/CW shortwave transceiver has a 1602 screen, built-in battery, charger, built-in microphone and speaker. It can be connected to an automatic button. It can also be CW decoded.
Feature:
- Using durable IRF series launch tubes
- Can be used to connect an antenna (instrument base)
-  marking on aluminum shell, all aluminum buttons, with translucent silicone buttons
- The original transformer qcx circuit is greatly simplified, and the installation components are reduced by 50%. No complicated windings. There is no wiring procedure. Most cost-effective and easy to construct
function list:
- Eer e-level drive SSB emitter stage
- 13.8v power supply about 10w ssb pep output
- Full mode support: usb, lsb, cw, am and fm-dsp
- Filters: 4000, 2500, 1700, 500, 200, 100, 50hz passband
- DSP functions: automatic gain control (agc), noise reduction (nr), voice trigger, voice trigger xmit, attenuator rx (att), tx noise gate, tx drive control, volume control and dbm/s-meter
- Ssb reverse sideband/carrier suppression transmit: better than -45dbc, imd3 (dual tone) -33dbc; receive: better than -50dbc
- Supports multiple frequency bands. Continuously adjustable in the frequency range of 160m-10m (loss of 20khz performance) ..99mhz
- Open source firmware, built-in ide; experiments are allowed, new functions can be added, and contributions can be shared through github, software complexity: 2000 lines of code
- V-based software for fast and full rogue operation (qsk and half-qsk), or auxiliary execution in digital mode (no cat or ptt interface) for rx/tx switching, with tx/pa delay control external ptt output - Simple installation and modification, 8 component changes and 8 lines
- Lightweight, low-cost transceiver: thanks to eer electronic level transmitter, it has high power efficiency (no huge heatsink required) and simple design (no complex balanced linear power )
- SSB transmitter phase is completely digital and software based: controls the phase of the si5351 PLL (via small i2c frequency changes over 800kbit/s) and the amplitude of the PA (via pwm to pwm) to test the microphone input and reconstruct the SSB signal. Key shaping circuit PA)
- All-digital and software-based SDR receiver stage (optional): I/Q signal (complex) is sampled from quadrature sampling detector digital mixer where 90 degree phase shift (Hilber transform) is performed in software and passed through Add and remove sidebands
- Three switchable analog controllers  of the front receiver
- 0db, -13db, -20db, -33db, -53db, -60db and -73db
- Mds receiver noise level: -135dbm (200hz bw) at 28mhz
- Front receiver selectivity: Steep frequency adjustment - 45db/decade roll-off +/- 2khz
- Blocking dynamic range: 123db at 20khz offset, 78db at 2khz offset
- CW decoder, direct/iambic-a/b keying-Vfo a/b + rit and crossover, switch corresponding relays with filters via i2c-Cat support (TS480 subset), can transmit audio over CAT for streaming mode transfer, keystrokes and display text
Interface introduction:
- Charging: Built-in lithium battery charging port, only use the included charger! Do not use chargers from other manufacturers
- Turn off. Bat: Built-in battery powered. 13.8: External power supply
- DC13.8v/3a: External power interface
- Key: Automatic key body connection (a, b, single key)
- Pa: external power , ptt signal
- Microphone: External microphone interface
- Uart: Serial communication (TS-480 compatible commands)
- Spk: External Speaker
