SDR Shortwave Radio Transceiver USDR USDX Mini 8 Band SSB CW QRP Transceiver 3.5 to 470MHZ 20W Item Type: SDR Shortwave Radio Transceiver Material: Aluminum Alloy Battery: 12.6V Lithium Battery 6000mAh x 1 ( Shipped With Built In Battery ) Feature List: Simple, Fun and Versatile CXP SSB HF Transceiver with Built In DSP and SDR Functions! Eer E Class Drive SSB Transmitter Stage. 13.8V Power Supply Approx. 10W SSB PEP Output Filters: 4000, 2500, 1700, 500, 200, 100, 50hz Passband DSP Functions: Control Auto Gain (agc), Noise Reduction (nr), Voice Trigger, Voice Trigger, Attenuator(att), tx Noise Gate, tx Drive Control, Volume Control, dbm/s meter SSB Reverse Sideband, Carrier Rejection Transmit: Better Than -45dbc, imd3 (Dual Tone) -33dbc, Receive: Better Than -50dbc Multiband Support, continuously adjustable over 160m-10m frequency range (loss of 20khz performance). .99mhz Open Source Firmware, Built Into Ide; Allows Experimentation, New Features Can Be Added, Contributions Can Be Shared Via Github, Software Complexity: 2000 Lines of Code V based software can be used for fast full rogue operation (qsk and semi-qsk) or assisted execution in digital mode (no cat or ptt interface) for rx, tx switching with tx, pa latency control external ptt outputs Simple Installation and Modification, 8 Component Changes and 8 Lines Lightweight, Low Cost Transceiver: Thanks to the eer e level transmitter, it has high power efficiency (no bulky heat sinks required) and simple design (no complex balanced linear power amplifiers required) 3 Switchable Analog Modulators Independent of Pre Receiver 0db, -13db, -20db, -33db, -53db, -60db, -73db Mds Receiver Noise Level: -135dbm (200hz bw) at 28mhz Pre Receiver Selectivity: Steep Frequency Tuning -45db, Decade Roll Off +, - 2khz Blocking Dynamic Range: 123db at 20khz Offset, 78db at 2khz Offset CW Decoder, Straight or Inhibit Grid -a or b Keying -Vfo a or b + Rit and Crossover, and switching of the corresponding relays with filters via i2c-Cat support (TS480 subset) allows streaming of voice, keystrokes and display text over CAT. This is probably the most economical and easy to build standalone sdr or ssb transceiver. Greater simplicity simplifies the original qcx circuitry (i.e., 50% fewer mounting components, 50% fewer mounting components, no complex transformer windings, no pairing procedures), greater versatility Port Introduction: Charging: Built in charging port for lithium batteries, only use the supplied charger! Prohibit the use of other chargers! Switch: Off, Bat: Built In Battery Power, 13.8: External Power Supply DC13.8V, 3a: External Power Connector. Key: Automatic Key Body Connection (a, b, Single Key) Pa: External Amplifier, PTT Signal Mic: External Microphone Interface Uart: Serial Communication (TS 480 Compatible Command) Spk: External Speaker, Lambic Fret -a or b Keying -Vfo a/b + rit and crossover, switching of the corresponding relay with filter via i2c Cat support (TS480 subset), possibility of transmitting the voice via CAT for streaming mode transmission, keystrokes and display of texts Tuner Parameters: FRQ: 3.5-30MHZ, 50-54MHZ, 76-108MHZ, 117-136MHZ, 136-174MHZ, 400-470MHZ SWR≤1.5 Power: 20W FM reception 76mhz-108mhz Can receive VHF UHF frequency. With function auxiliary transmission Frequency adjustment by knob; band switch to select high and low shortwave bands. Top with M4 male connector. M male output or BNC male connector.
