8 tracks cover 80m/60m/40m/30m/20m/17m/15m/10m. Excellent PCB layout design in line with high-frequency circuit design principles to ensure excellent performance. Whether using built-in battery or external 13.8v power supply, 8 gears of 3-5w power can be achieved, and necessary sot-223 and to-220 pack pads are reserved for upgrade. High transmission efficiency, 80m/60m/40m/30m/20m efficiency greater than 80%, 17m efficiency greater than 70%, 15m/10m efficiency greater than 60%. KDS high-precision tcxo brand, frequency accuracy better than 1ppm, frequency stability better than 0.5ppm. Ultra-small size: 88x39x124mm (excluding protruding parts). Rich interfaces (cat, ptt out, mic/key, k-head mic). All LPF parts use 100v c0g/np0 capacitors. Use genuine Omron magnetic latching relays. Use lower noise op amp chips than lm4562. Built-in speaker with cavity. BNC antenna interface. Move the headphone and power button/microphone jacks to the front panel for easy connection of headphones and power buttons. Move the buttons to the bottom of the LCD screen for a larger touch area and a more comfortable button experience. Upgrade the built-in speaker effect, double the sound! The PCB reserves the pads required for various upgrades, ready to use out of the box, and can be used as a template for DIY upgrade learning Quickly change the qrp cw frequency. Support cw sidetone volume adjustment. Support cw sidetone adjustment. This is a shortwave qrp ssb/cw transceiver. The ultra-small size is easy to carry for outdoor use (with or without battery, built-in 4000mAh lithium battery) 1602n LCD screen, built-in speaker, support connecting to a computer to use FT8, JS8, FT4 and other mode software to control digital, support cw automatic decoding. Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on. voltage: AC220V Colour:Black Material:Metal Package Contents: 1 * Shortwave 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.
