Handheld USDX USDR HF QRP SDR Transceiver SSB/CW 8-Band 5W DSP SDR+Battery+ Mic

Description: Description HanGeek USDR+ 5W QRP HF 8-Band SDR Transceiver FT8 USB LSB CW FM AM HF Transceiver with MicrophoneDescription:HanGeek USDR+ is a HF QRP SSB transceiver. It is easy to carry for outdoor use thanks to ultra-small size. The SDR transceiver is designed with a 4000mAh built-in lithium battery, a 1602N LCD screen and a built-in speaker. It can be connected to a PC to control radio frequencies using digital mode software such as FT8, JS8 and FT4. See the pictures below for specific wiring definition.Features:- Excellent PCB layout design in line with the principles of high-frequency circuit design to ensure excellent performance- Whether using internal battery or external 13.8V power supply, it can reach 3-5W in 8 bands. SOT-223 and TO-220 package pads are also reserved for retrofits- High transmitting efficiency: 80m/60m/40m/30m/20m efficiency is higher than 80%, 17m efficiency is higher than 70%, and 15m/10m efficiency is higher than 60%- High-precision original TCXO for KDS: Frequency accuracy is better than 1PPM and frequency stability is better than 0.5PPM- Ultra-small size: 83 x 38 x 124mm/3.3 x 1.5 x 4.9" (excluding protrusions)- Abundant interfaces: CAT, PTT OUT, MIC/KEY and K-type handheld microphone- LPF part is all made of 100V C0G/NP0 capacitors- It uses original magnetic latching relay for Omron- The noise of op amp chip is lower than that of the LM4562- Built-in speaker with cavity- 11.1V (12.6V) built-in lithium battery- BNC antenna interfaceFunctions:- Support full mode: USB, LSB, CW, AM and FM (SSB mode has good reception effect, poor transmitting effect. AM, CW, and FM modes are gifted and the effects of these modes are not guaranteed)- DSP filter: 4000, 2500, 1700, 500, 200, 100 and 50Hz pass band- DSP Functions: Automatic Gain Control (AGC), Noise Reduction (NR), Voice Operated Xmit (VOX), RX Attenuator (ATT), TX Noise Gate, TX Drive Control, Volume Control and dBm/S Meter.- SSB to side-band/carrier suppression transmission: better than -45dBc, IMD3 (two-tone) -33dBc and reception better than -50dBc- Support multi-band: continuously adjustable through 10m-80m frequency band (20kHz...99MHz, with performance loss)- Open-source firmware: built with Ar-duino IDE; experiments are allowed, new features can be added, contributions can be shared via Github; software complexity: 2000 lines of code- Software-based VOX can be used as quick full control (QSK and semi-QSK operation) or auxiliary RX/TX switched to operate digital mode (no CAT or PTT interface required), external PTT output/PA control-delay with TX- All-digital and software-based SSB transmission stage: by controlling the phase of SI5351 PLL (via small frequency changes on 800kbits/s I2C) and the amplitude of PA (via PWM PA key shaping circuit)- All-digital and software-based SDR receiver stage (optional): Sample I/Q (complex) signals from an orthogonal sample detector digital mixer and mathematically perform a 90-degree phase shift (Hilbert transform) in the software and cancel out one by adding a side-band- Three independent switchable analog front-end receiver attenuators (0dB, -1 3dB, -20dB, -33dB, -53dB, -60dB and -73dB)- Receiver noise floor MDS: -135dBm at 28MHz (200Hz BW)- Receiver front-end selectivity: +/-2kHz steep -45dB/decade roll-off from tuning frequency- Blocking dynamic range: 20kHz offset 123dB and 2kHz offset 78dB- VFO A/B+RIT and Split, as well as the corresponding relay with filter switching via I2C- CAT supports (TS-480 protocol for KENWOOD) operation: Currently, the following functions have been assigned to shortcut buttons (L=Left, E=Encoder & R=Right) and menu items: Menu function buttons1.1 vol1.2 mode1.3 filterbw1.4 band1.5 tune rate1.6 vfo mode1.7 rtt1.8 agc1.9 nr1.10 att1.11 att21.12 s-meter1.13 swr meter2.4 semi ask2.8 practice3.1 vox3.2 noise gate3.3 tx drive3.5 mox8.1 ta bias8.2 pa max8.3 ref frq8.4 iq phase8.6 cat115k8.7 quad10.1 lightPackage Included:- 1 x Main unit- 1 x Handheld Microphone- 1 x Power adapter- 1 x Power cable Payment Terms 1.
