It is optimized fromuSDX QCX-SSB open source hardware. The powerful software supports the use of less hardware to complete the SW transceiver and supports the SSB mode (reception quality is very good, transmission quality is slightly worse). The hardware has the following features. Shell size: 82.8mm 28.8mm 110mm. Interaction and display: rotary encoder; Menu + exit key; 1602n LCD. Headphone output connector (marked HP). Cat and PTT_ Out interface (marked with cat). Mic microphone and key interface (marked mic / key). K-head hand microphone or headset interface (Jianwu line sequence, marked kJ). The antenna interface is BNC interface. The power interface is 5.5 2.0. Built in horn with cavity (general effect). Support 8 frequency bands. 80-meter band (3.5MHz). 60-meter band (5.3MHz). PA structure and output power. Three TO-92 packaged bs170 tubes are used, and the transmission power is 3-5w (one bs170 and irf530 pad are reserved for DIY upgrade). Working voltage: 9-13.8v (maximum 15V, but not recommended, and the transmission power will drop below 13.8V). All known defects have been modified, but I hope it will keep the original design as much as possible, so that lovers can query more information on the above website, so as to facilitate DIY or grinding in the later stage. The hardware indicators of this Sales meet or exceed the original design. However, DIY equipment cannot be compared with commercial machines. There may be such or such defects. If you choose, you will be accepted. Other notes: the operational amplifier chip lm4562 is genuine; The relay is genuine Omron dismantling machine. Please consider it carefully if you care. The frequency will be roughly calibrated before the finished machine is delivered (error + – 10Hz). Some tips on using. Due to software defects, the volume adjustment is not perfect. It is recommended that the volume should not exceed 13 and 14-16 during normal use. It is prepared for weak signals. When your receiving signal is weak, you can turn up the volume appropriately. If you feel the volume is not high enough, you can use an external active speaker (connected to the HP port) or an external 8 ohm 1W large speaker (connected to the kJ port). For some weak signals, try to turn off AGC or set AGC to fast and att2 to 0, which will have better reception effect. Due to the extremely simple hardware structure, the sensitivity will weaken with the increase of frequency, so it is recommended to turn off AGC at high frequency and set att2 to 0. Sensitivity is also reduced at frequencies supported by non amateur radio bands. The interference of switching power supply is relatively large. It is recommended to use linear power supply instead of switching power supply. Without power control circuit, the output power will change greatly with whether the antenna resonates or not. Do not supply power to the PA board alone during the mill and transformation. When the core version is not connected, supplying power to the PA board alone will cause self excitation and damage the PA transmitting tube. Do not use active antenna to transmit, otherwise your antenna will be damaged. Since there is no limiting device, if the input signal is too strong, the hardware may be damaged (it can not be determined yet).

8 Band SDR All Mode HF Transceiver. Please note this and make sure you can accept this before you make the order Thanks!! It is optimized from open source hardware. The powerful software supports the use of less hardware to complete the SW transceiver and supports the SSB mode (reception quality is very good, transmission quality is slightly worse). The hardware has the following features. Case size : 82.8MM28.8MM110MM. Interaction and display: rotary encoder; MENU+EXIT button; 1602N liquid crystal display; headphone output interface; CAT interface; PTT_OUT interface (used to control external power amplifier); MIC microphone interface; electric key interface; K-head microphone or headset interface (built 5 wire sequence); antenna interface is BNC interface; power interface is 5.52.0 specification. Built-in speaker with cavity (general effect). Support 8 frequency bands. 80-meter band (3.5MHz). 60-meter band (5.3MHz). Three TO-92 encapsulated BS170 tubes are used, and the transmitting power is 3-5W (reserve a BS170 and IRF530 pad for DIY upgrades). Working voltage: 7-13.8V (up to 15V but not recommended, transmission power will decrease if it is lower than 13.8V). However, I hope that it maintains the original design as much as possible, so that fans can find more information on the above-mentioned website to facilitate later DIY or Mill. The PLL uses 0.5PPM TCXO temperature compensated crystal oscillator. The LPF part uses 100V NP0/C0G capacitors, imported powder magnetic rings, and relays. It is an Omron magnetic latching relay. However, DIY equipment cannot be compared with commercial machines. There may be one or other defects. The choice is acceptance, please be aware. Other instructions: The op amp chip LM4562 is a genuine disassembly machine; the relay is a genuine disassembly machine from Omron. Please consider carefully if you are concerned. Usually it cost about 35USD-50USD. Thanks for your understanding. If you receive defective item, please kindly notify us within 14 days. The item “10/15/17/20/30/40/60/80m 8 Band SDR All Mode HF SSB QRP Transceiver Ham-USDR” is in sale since Monday, July 26, 2021.
