I am very happy with the performance of the transceiver.
There is no other QRP like it, great quality at a reasonable price.
Stop looking and buy an MCHF here.

Cheresdi Ioan Dorin –
I built a small sdr, I liked how it works, but I wanted an “industrial” one and so I bought MCHF SDR assembled by rowaves. I’m more than satisfied. Lightweight, small, powerful, perfect for portable with a Lipolymer battery. Thanks RoWaves. YO7LRC, Doru

The mcHF SDR arrived in perfectly working order, it’s indeed a very good radio. Andrei and his team did a great job assembling it and very rapidly answered some questions via e-mail, going above and beyond what is expected.

Ordered the fully assembled receiver beginning of 2021 when I was still in training for my license. Works as intended, would buy it again.

Mirek, OK2FUG (verified owner) –
I knew mcHF from Youtube and reviews only. Now that I have it in my hand, it exceeded my expectations. I’m very satisfied. Selectivity, sensitivity, waterfall, transmitter power, everything is a dream come true for a QRP amateur. Fast delivery and a flawlessly functioning radio after assembly by this service is absolutely perfect. I would appreciate option of choosing an antenna connector between BNC and SMA. The mcHF has a slightly higher power consumption during receiving, maybe it would be solved by changing the CPU, eg STM32L4 series.
