Description: Usdr Usdx+ Plus V2 8-SDR Full Mode HF Ham Radio SSB QRP Transceiver Durable DESCRIPTION Product Description:* Brand new and high quality* Made of high quality materials,* This is a shortwave QRP SSB/CW transceiver. It is ultra-small and easy to carry outdoors. It uses a 1602N LCD screen and a built-in speaker. It supports connection to a PC. It can be controlled by digital mode software such as FT8, JS8, FT4, etc., and supports CW automatic decoding.notes:* This product has no built-in battery and no power supply. It needs to be equipped by the user. Please make sure you dont mind before purchasing!!!* The power interface is 5.5mm, the power supply voltage is 12.6V, and both 1A and 2A can be used.* Battery specifications are 11.1V/12.6V 4000mAh lithium battery.* You can purchase a power supply or battery based on the above values, thank you.Features:* 8 tracks covering 80m/60m/40m/30m/20m/17m/15m/10m* Excellent PCB layout design, in line with high-frequency circuit design principles, ensuring excellent performance* Whether using the built-in battery or an external 13.8V power supply, 8 levels of 3-5W power can be achieved, and the SOT-223 and TO-220 Pack pads required for upgrades are reserved.* 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-precision 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)* Rich interfaces(cat, ptt out, mic/key, k-head mic)* All LPF parts use 100v c0g/np0 capacitors* Use gen uine Om ron orig inal magnetic latching relay* Use an op amp chip with lower noise than LM4562* Built-in cavity speaker* BNC antenna interfaceusdx+ is updated as follows:- Moved the headphone and power key/microphone j ack to the front panel for easier access to the headphone and power buttons.- Move the keys to the bottom of the LCD screen for a larger touch area and a more comfortable keystroke experience.- The built-in speaker effect to double the sound!- PCB reserves various pads, ready for use out of the box, and can be used as a template for DIY learning- Quickly change qrp CW frequency.-Supports CW sidetone volume adjustment.- Supports CW sidetone adjustment.function list:1. Support all modes: usb, lsb, cw, am, fm(ssb mode has good receiving effect, but poor transmitting effect. AM and FM modes are free, but the effect is not good)Filter for DSP filter: 4000, 2500, 1700, 500, 200, 100, 50hz passba2. Function for 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.3. Sidebar/Carrier Suppression SSSSB Transmit: Better than-45dbc, imd3(dual tone)-33dbc, Receive: Better than-50dbc4. Supports multi-ba support, continuously adjustable 10m within the 80m frequency range(from 20khz..99mhz, loss performance)5. Open source firmware, built using Ardu ino IDE; allows experimentation, new features can be added, contributions can be shared via github, software complexity: 2000 lines of software-based Vovox cod e 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 level transmitter in digital mode(no need for cat or ptt interface): control phase of sill si5351(via 800kbits under i2c/s for switching) and the amplitude of the PA(through the PWM PA key shaping circuit)6. Software-based all-digital receive stage(optional): I/Q(complex) signals are sampled from a quadrature sampling detector digital mixer and mathematically performed in software by 90-degree phase shifting(Hilbert special transform) and three indepe ndent switchable analog faders(0db,-13db,-20db,-33db,-53db,-60db,-73db) from the pre-receiver by adding atten sideba nds7. Receiver noise floor mds:-135dbm at 28mhz(200hz bw)8. Receiver front-end selectivity:+/-2khz steep 45db/ten times tuning frequency rolling9.
