This is an SDR HF QRP transceiver that has been popular all over the world since its launch and has at least 30,000 users so far. Its advantages are: small and portable, cost-effective, full-featured, and direct selection of software radio circuit models. For electronics enthusiasts who like DIY and hardware, this is a very good hands-on tool. It can be used to familiarize yourself with the working principle of amateur radio transceivers; for software enthusiasts who write code programming and code farmers, you can also use this hardware to modify the source code by yourself, add or reduce some functions, and give full play to your code farmers. With technical ability, you can modify and upgrade the software of this machine at will. For college students studying electronic technology, it can be used to test their own learning level. And QRP communication enthusiasts can use the assembled kit for various outdoor QRP communication, especially digital communication using PSK31, RTTY and JT65. For emergency communication, it is a small and portable emergency communication equipment.
