Description:
This is a shortwave druse ssb/cw transceiver. It has 1602 screen, built-in battery, equipped with charger, built-in microphone, built-in speaker! It can be connected to an auto key and can be cw decoded.
Characteristics:
-Using Osmo series launch tube, durable
-Can be used by connecting the antenna (M seat)
-8 bands. Power wave digital display! 13.8v 10w maximum external power! Built-in 12.6v battery
-Dimensions: 76x46x130mm/3x1.8x5.1"
-Provides FT8 option connector later
-Use tcxo for kds. Accuracy 0.5ppm (1ppm per year)
- Aluminum shell laser marking
-Fully aluminum buttons! Translucent silica gel button (receive green, emit red)
Function list:
- Simple, interesting and versatile cxp ssb HF transceiver with built-in dsp and sdr functions
- EER electronic level driven SSB launch stage
- 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: Auto Gain Control (AGC), Noise Reduction (NR), Voice Trigger, Xmit Voice Trigger (VOX), Attenuator RX Attenuator (ATT), TX
Noise gate, TX driver control, volume control, dbm/s meter
- Sideband Reverse SSB/Carrier Suppression: better than -45dbc, imd3 (two tone) -33dbc, reception: better than -50dbc
-Multi-band support, continuously adjustable in 160m-10m frequency band (and 20khz..99mhz performance loss)
-Open source, integrated firmware for Arduino IDE; allows experimentation, can add new functions, can share contributions via github, software complexity: 2000 lines of code
-Software based VOX can be used as a quick and full raid (QSK and Semi-QSK operation), or to assist in running in digital mode (no cat or ptt interface) for rx/tx switching, external delayed ptt output control tx/pa
-Simple installation modification with 8 component changes and 8 wires
-Lightweight and cost-effective transceiver: thanks to the level and eer transmitter, it has high energy efficiency (no bulky heat sink needed) and simple
Design (no complex balanced linear power amplifiers required)
-SSB transmitter stage entirely based on digital and software: by controlling the phase of the PLL SI5351 (through the small frequency shift of I2C above 800kbit/s) and the amplitude of the PA (through the PWM of PWM) to sample the microphone input and reconstruct the ssb signal. Pa key shaping circuit)
-Software-based, all-digital SDR receiver stage (optional): samples the I/Q (complex) signal from the digital mixer from the square sampling detector, and perform a 90 degree phase shift in the software (hilber transform) and eliminate one by adding sidebands
-Three independently switchable analog front receiver faders (0db,-13db,-20db,-33db,-53db,-60db,-73db)
- MDS receiver noise level: -135 dbm (200hz bw) to 28mhz
- Receiver front selectivity: Steep tuning frequency -45db/ten times roll-off/-2khz
- Lock dynamic range: 20khz offset 123db, 2khz offset 78db
- CW decoder, straight/iambic-a/b keyboard
-Vfo a/b scrit and split, and switch the corresponding relay band filter via i2c
-Support for cat (TS480 subset), you can stream audio, press keys and display text through cat
-This is probably the most economical and easiest to build standalone SDR/SSB transceiver. Great simplification simplifies the original QCX circuit (i.e. reduces installation components by 50%, reduces installation components by 50%, does not require complex transformer windings and does not require alignment procedures), and is more versatile
