Features: This is a shortwave QRP SSB/CW transceiver. The ultra-small size makes it easy to carry for outdoor use. It adopts 1602N LCD screen, built-in speakers. Support to connect to PC and use FT8, JS8, FT4 and other digital mode software control, support CW automatic decoding. 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). In addition, the developer also developed an AM/FM mode for it, but AM/FM is defined as a gift function. Don'for t expect AM/FM too high. Excellent PCB layout design in line with high-frequency circuit design principles to ensure excellent performance.
