USDX SDR ORP HF Transceiver R1.02W 5W 40M 15M 20M 3 Band SDR All Mode USB, LSB, CW, HF SSB QRP Transceiver with Mic

<ul><li>Simple, interesting and versatile QRP SSB HF transceiver with embedded and SDR functions.EER E-level driven SSB launch stage. 12V power supply provides about 5W Max PEP SSB output. Full mode support: USB, LSB, CW, AM, FM. filter: 4000, 2500, 1700, 500, 200, 100, 50Hz passband. function: automatic gain control (AGC), noise reduction (), voice trigger, voice trigger Xmit (), RX attenuator attenuator (ATT), TX noise gate, TX driver control, volume control, dBm/S-meter.</li><li>Software-based can be used as a fast full invasive (QSK and semi-QSK operation), or to assist in running in digital mode (without CAT or PTT interface) for RX/TX switching, external PTT output with TX/PA control-delay. Simple installation modification with 8 component changes and 8 wires. , low-cost transceiver: Thanks to EER transmitter E-level, it has high power efficiency (no bulky heat sink required), and simple design (no need for complex balanced linear power amplifiers).</li><li>SSB reverse sideband/carrier suppression transmission: -45dBc, IMD3 (two tones) -33dBc, reception: -50dBc. Multi-band support, continuously adjustable in the 160m-10m frequency band (and performance loss from 20kHz to 99MHz). Open source firmware, built in for IDE; allows experimentation, can add new functions, can share contributions through Github, software complexity: 2000 lines of code.</li><li>SSB transmitter stage based entirely on digital and software: By controlling the phase of the SI5351 PLL (via the tiny frequency change of over 800kbit/s) and the amplitude of the PA (via the PWM of PWM) to sample the microphone input and reconstruct the SSB signal. PA key shaping circuit).</li><li>This is a shortwave QRP SSB/CW transceiver. It boasts 1602 screen, built-in mic, built-in speaker! It can be connected to an automatic key, and can be decoded by CW. Using IRF series launch tube, . Can be used by connecting the antenna (BNC connector) 3 bands. Power standing wave digital display! Aluminum shell laser marking.</li></ul>

Fully digital and software-based SDR receiver stage (optional): sample the I/Q (complex) signal from the quadrature sampling detector digital mixer, and perform a 90-degree phase shift in the software (Hilber transform) and one by adding sidebands. Three switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB). Receiver noise level MDS: -135 dBm (200Hz ) at 28MHz. Receiver front-end selectivity: steep tuning frequency -45dB / ten times roll- +/- 2kHz. Blocking dynamic range: 20kHz offset 123dB, 2kHz offset 78dB. CW decoder, straight/Iambic-A/B keyer. VFO A/B + and and Split, and switch the corresponding relay band filter through . CAT support (TS480 subset), you can stream audio, keys, and display text through CAT. This is probably the most cost-effective and easy to build standalone SDR/SSB transceiver. Great simplification Simplifies the for-original QCX circuit (that is, reduces the installation components by 50%, reduces the installation components by 50%, does not require complex transformer windings, and does not require alignment procedures), and is more versatile. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use. Colour:Black Material:Metal+Plastic Dimensions:80 x 40 x 100mm Package Contents: 1 * Transceiver Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
