usdx usdr hf s7p sdr transceiver ssb/cw 8-band 5w dsp sdr transceiver with black housing for amateur radio

software:
//github.com/threeme3/QCX-SSB/tree/feature-rx-improved

describe:
This is a shortwave druse ssb/cw transceiver. 1602 screen, built-in battery, equipped with charger, built-in microphone, built-in speaker! It can be connected to an automatic key, which can be decoded by cw.

feature:
-Using osmo series launch tube, durable
-Can be used by connecting the antenna (seat m)
-8 band. Radio wave digital display! The maximum external power supply is 13.8v 10w! Built-in 12.6v battery
-Size: 76x46x130mm/3x1.8x5.1"
-Ft8 option connector will be provided later
-Use tcxo for kds. 0.5ppm accuracy (1ppm per year)
-Aluminum shell laser marking
-All aluminum buttons! Translucent silicone button (receive green and red)

function list:
-Simple, fun and versatile cxp ssb high frequency transceiver with built-in dsp and sdr functions
-SSB launch phase triggered by eer electronic level
-13.8v power supply provides about 10w ssb output
-Full mode support: usb, lsb, cw, am, fm
-dsp filter: password 4000, 2500, 1700, 500, 200, 100, 50hz
-dsp function: automatic gain control (agc), noise reduction (nr), voice trigger, voice trigger xmit (vox), attenuator rx attenuator (att), tx
Noise gate, tx driver control, volume control, dbm/s meter
-Sideband reverse/carrier suppression ssb: better than -45dbc, imd3 (dual tone) -33dbc, reception: better than -50dbc
-Multi-band support, continuously adjustable in the 160m-10m frequency band (and 20khz.. 99mhz performance loss)
-Open source firmware, integrated for arduino ide; allows experimentation, can add new features, can share contributions through github, software complexity: 2000 lines of code
-Software-based vox can be used as a fast and complete hack (qsk and semi-qsk operations), or to assist in running in digital mode (no cat or ptt interface) for rx/tx switching, external ptt output with delay tx /pa control
-Simple installation and modification, 8 component changes and 8 wires
-Lightweight and low-cost transceiver: Thanks to the eer level and transmitter, it has high energy efficiency (no need for bulky heat sink) and simple
Design (no need for complex balanced linear power amplifiers)
-Fully digital and software-based ssb transmitter stage: by controlling the phase of pll si5351 (through small i2c frequency changes above 800kbit/s) and the amplitude of pa (through pwm of pwm) to sample the microphone input and reconstruct the ssb signal . Key shaping circuit pa)
-All-digital, software-based sdr receiver stage (optional): sample the i/q (complex) signal from the digital mixer of the square sampling detector, and perform a 90-degree phase shift (Hilber transform) in the software ) And remove a sideband by adding
-Three independent switchable analog front receiver faders (0db, -13db, -20db, -33db, -53db, -60db, -73db)
-Mds receiver noise level: -135 dbm (200hz bw) to 28mhz
-Front receiver selectivity: steep adjustment frequency -45db/ten times roll-off/-2khz
-Dynamic blocking range: 20khz offset 123db, 2khz offset 78db
-Cw decoder, direct keyboard/iambi-a/b
-vfo a/b script and split, switch the corresponding relay band filter through i2c
-Support cat (subset of ts480), can stream audio, keystrokes and display text through cat
-This is probably the most economical and easiest to build standalone sdr/ssb transceiver. Greater simplification simplifies the original qcx circuit (that is, the installation components are reduced by 50%, the installation components are reduced by 50%, no complicated transformer windings, and no wiring procedures are required), and the versatility is stronger

Port introduction:
-Charging: Built-in lithium battery charging port, only the supplied charger can be used! It is forbidden to use other chargers!
-Switch: Turn off to turn off. Bat: Built-in battery power supply. 13.8: External power supply
-DC13.8v/3a: External power interface
-Key: Automatically connect the key body (a, b, single key)
-Pa: external power amplifier, ptt signal
-Microphone: external microphone interface
-Uart: Serial communication port (compatible with OSM)
-Spk: external speakers
