8 Band SDR All Mode HF Transceiver. Please note this and make sure you can accept this before you make the order Thanks!! Type: HF QRP SDR Transceiver.
Rf output: 10W max at 13.8V exit DC in. 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).
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. If you receive defective item, please kindly notify us within 14 days.
