⭐usdx+ HF Shortwave Transceiver QRP SSB/CW Transceiver 3W-5W All Mode 8 Band Upgraded Version of usdx

Note:

This product has no built-in battery and no power source. It needs to be equipped by the user. Make sure you don't mind before buying! ! !

The battery specification is 11.1V/12.6V 4000mAh lithium battery. 

If you need batteries, you can buy power or batteries according to the above values, thank you.

Description:

This is a shortwave QRP SSB/CW transceiver. The ultra-small size is easy to carry for outdoor use, using 1602N LCD screen, built-in speaker, support to connect to PC, use digital mode software control such as FT8, JS8, FT4, etc., support CW automatic decoding.

Features:

✅8 tracks cover 80m/60m/40m/30m/20m/17m/15m/10m

✅Whether using internal battery or external 13.8v power supply, it can achieve 3-5w power in 8 ranges, and reserve SOT-223 and TO-220 pack pads needed to upgrade

✅High emission efficiency, 80m/60m/40m/30m/20m efficiency is greater than 80%, 17m efficiency is greater than 70%, 15m/10m efficiency is greater than 60%

✅High accuracy KDS brand TCXO, frequency accuracy is better than 1ppm, frequency stability is better than 0.5ppm

✅Ultra small size: 83*38*124mm (excluding protruding parts)

✅Abundant interfaces (cat, ptt out, mic/key, k-head mic)

✅All LPF parts use 100v c0g/np0 capacitors

✅Use genuine Omron original magnetic latching relays

✅Use op amp chip with lower noise than LM4562

✅Built-in speaker with cavity

✅BNC antenna interface

List of Functions:

🛠️ Support all modes: usb, lsb, cw, am, fm (ssb mode has good reception effect, but poor transmission effect. AM and FM modes are free, and the effect is not good)

Filter dsp filter: 4000, 2500, 1700, 500, 200, 100, 50hz passband

🛠️ Function DSP functions: automatic gain control (AGC), noise reduction (NR), Xmit voice trigger (VOX), RX attenuator (ATT), TX noise gate, tx unit control, volume control, dbm/s meter.

🛠️ Sidebar/Carrier Suppression SSSSB transmit: better than -45dbc, imd3 (dual tone) -33dbc, receive: better than -50dbc

🛠️ Support multi-band support, continuously adjustable 10m within 80m frequency range (from 20khz..99mhz, loss performance)

🛠️ Open source firmware, built with arduino ide; allows experimentation, new features can be added, contributions can be shared via github, software complexity: 2000 lines of software-based Vovox code available for fast full control (qsk and half-qsk operations) or rx/ Auxiliary switch tx for external control of ptt/pa output using fully digital tx-delay stage and software based ssb stage transmitter in digital mode (no cat or ptt interface required): controls the phase of the sill si5351 (by switching at 800kbits/s Small frequency changes under i2c) and magnitude of pa (via pwm pa key shaping circuit)

🛠️ Software-based all-digital SDR receiver stage (optional): The I/Q (complex) signal is sampled from a quadrature sampling detector digital mixer and a 90 degree phase shift is performed mathematically in software ( Hilbert transform) and three independently switchable analog faders (0db,-13db,-20db,-33db,-53db,-60db,-73db) from the pre-receiver by adding Atten sidebands

🛠️ Receiver noise floor mds: -135dbm at 28mhz (200hz bw)

🛠️ Receiver receiver front-end selectivity: +/-2khz steep 45db/decade tuning frequency rolling

🛠️ Blocking blocking dynamic range: 20khz offset 123db, 2khz offset 78db

🛠️ cw decoder, direct/iambic-a/b keyer

🛠️ vvfo a/b + rit and split, and the corresponding relay through i2c

🛠️ cat supports cat with filter switch (using kenwood TS-480 protocol)
