I just received the JUMA PA100-D from roWaves. Shipping to the US was extremely fast, just 3 or 4 days. I’m using the amp with an Icom IC-705 in Auto Band Detection-Freq. Sense Mode and it is working great. I really like how you can control the gain and the fan is so quiet. Don’t hesitate to order if you’re from the US, the communication from Andrei is great and no issues with shipping. There is not a better amp price/performance wise available for your QRP radio.

The roWaves Juma PA-100D is an excellent 100+W amplifier. It is just the thing for adding some punch to your QRP signal when needed. It is a quality built unit and offers tremendous features, many which were unexpected by me. See it in action on YouTube with Andrei-YO6TJJ giving the demonstration. I love this little amp! Andrei and the entire roWaves team are a joy to work with. My transaction was without any difficulty and the unit shipped stateside very quickly. More importantly Andrei and his team are dedicated to superior customer service and support. Buy from roWaves with total confidence as Andrei and the team are the real deal !

Cool amplifier ! Exactly what I needed to field work. The build quality is respectable. Quiet fans. The controls are simple and straightforward. I used this amplifier to work in SSB, CW and Digital modes. An excellent choice for the price !

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.

Bought this RX-1 receiver as a receiver for when not in the shack. Tuned wire antenna and this little rig receives everything I want to hear.

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

The JUMA PA100-D is a great and nice amp and was built very well by roWaves. This is a professional team. When connected to my Juma TRX, 817 Ft and KX3 I use it in CW and SSB mode. It usually runs at 50W-90W so it doesn’t heat up and the fan is quiet. For me, the right choice in terms of price / performance as well. My recommendation !

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.

JUMA PA100-D is a great amplifier and very well built by the roWaves Technologies team. I use it connected to my SunSDR2-Pro for digital communications on FT8. It usually runs at 30W-50W so it doesn’t heat up and the fan is quiet. For me, the right choice is also in terms of price / performance. My recommendation !

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, 73.

Beautiful amp. Exactly what I was looking for. Well built and well thought. I use it between my SUNSDR2pro and my KPA500/ACOM2000. The fact to be able to control the amp gain is a charm. Now thinking on the PA1000, Congrats !

I am very satisfied with this product from roWaves Technologies. The amplifier has been carefully assembled and extensively tested before it was shipped. After shipping I had already received the amplifier within 2 days. Highly recommended.

roWaves is a young and motivated team that puts passion in everything what they do. I bought a DSB 80-meter band transceiver, some time ago, and I was pleasantly impressed with both the practical implementation and performance. I strongly recommend roWaves and, as a mention, Andrei – YO6TJJ – is a great guy.
