Feature:1. RADIO TRANSCEIVER: Shortwave QRP SSB CW radio transceiver, with clear LCD display, support connection to computer, use FT8, JS8, FT4 and other mode software to control digital.2. REASONABLE DESIGN: Headphone and power button and microphone jack are on the front panel for easy connection of headphone and power button, with larger touch area and more comfortable key experience.3. WITH SPEAKER: Upgraded built in speaker effect, stable sound and less interference, fast change of QRP CW frequency, and support CW side volume adjustment.4. HIGH EFFICIENCY: The transceiver has an 8 band design, covering 80m, 60m, 40m, 30m, 20m, 17m, 15m and 10m frequency, which has high transmission efficiency.5. OTHER FUNCTIONS: This radio transceiver has multiple interfaces, with built in speaker with cavity and BNC antenna interface, and all LPF parts use 100v c0g/np0 capacitors.Specification:Item Type: Radio TransceiverSize: Approx. 83 x 38 x 124mm / 3.3 x 1.5 x 4.9in (excluding protruding parts)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)DSP Filter: 4000, 2500, 1700, 500, 200, 100, 50hz passbandDSP 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 -50dbcSupport multi-band support, continuously adjustable 10m within 80m frequency range (from 20khz to 99mhz, loss performance)Software Complexity: 2000 lines of software-based Vovox cod
