MCHF V0.6.3 HF SDR Transceiver QRP Amateur Ham Radio |

Shopping instructions:

1. The MCHF transceiver is based on an open source project. Please make sure you have a full understanding of it on the Internet before purchasing it. Both advantages and disadvantages need to be understood by yourself.

2. All MCHF transceivers sold in our store are made by our DIY. Minor defects in the shell, imperfect workmanship, and even minor problems are unavoidable. Please do not place an order if you cannot accept it.

3. Most people feedback that the SWR form of mcHF is not easy to use. This should be the defect of the design of mcHF itself.

4. You can also ask customer service for relevant instructions before purchasing.

Description:

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.
