Review: Works well, but... there is always a "but" - Got a replacement for one of my orders where one of the AFT504 Transistors were broken out of the box. That was a super fast replacement without may questions. Can't test the board yet, but looks better than all my orders before No cold soldering, all pins are short and will not poke the radioberry. The white pins are my soldering. so don't take them as a reference for aursincs work. but, there is always a "but". the wires on the transformer are a bit long this time. i think that might cost just some milliwatts. All in all, i'm very happy with aursinc. meanwhile i build over ten devices and only one part was defective after recivement. To the customers: Hint 1: Use cooling. A fan, a coling plate, whatever. Hint 2: The AFT504 is made for 7.5v, so don't use 8v for longer time without a hard cooling. You will just miss some milliwatts on 7.5v. To the producer: Please rebuild and add a solution to cool the transistors. Example; Just a hole between the two transitors, so we can screw a coling plate on it. And/ or, made them easier to replace. The AFT504 isn't a long live product. It's qite hard to resolder them. The white pins are my soldering. s don't take them as a reference for aursincs work. old review for preamp v2 (end of april 2025): New version, new order and new quality ( preamp v2): it is a amazing little amplifier. got the radioberry setup running on 4 - 5 watts on all hf bands. sadly the board has still no hole to screw a cooling plate on the transistors. maybe available on version 3 of this board. :) Cooling plate issue fixed by parts out of the scrap box. old review for preamp v1: It is my second order. Found lot of cold soldering. On the other hand some of the solder points are so big, example sma, that they connect to radioberry board when mounted. first order was "okay". At all: check before mounting and fix it or send it back. whatever.
Review: Works Good - Very nice product. BUT the instruction are not good, as well as the unreachable link to download the test file. I already connected it to my Radio berry, with the raspberry pi-4. and it works fine

## Features

- New Version V2: The output power of the amplifier board V2 is slightly higher than that of the previous version, with V2 reaching 3–5W. Technical Specs: Power in 6-8V (8.4V preferred); HF Power in: Tx from radioberry; HF Power out: 3-5W for for HF amplification. RF range: 1mhz-50mhz. Port Type: Input SMA, Output SMA. Supports SSB, FM, and AM
- Designed for Radioberry SDR: This radioberry preamp board V2 is a nice addition to turn the radioberry into a small QRP radio. Seamless compatibility with Radioberry boards, making it a clean plug-and-play-style expansion, increased capability for your Radioberry
- Amp board integrates with RPi 4: Pairs with Pi 4/4B for those building a Raspberry Pi-based QRP SDR radio, combining digital signal processing and radio functionality in a small form factor
- What's Inside: 1x Radioberry Preamp Board; 3x SMA cable (1 for Rx ,1 for Tx,1 for ANT); 1x 8V Battery-powered Wire; 1x Connecting Row Needle; 4x Screw and Nut; 8x Plastic Column. Compact & Lightweight: Ideal for portable SDR radio setups, field use, or minimalist shack builds
- How to Work: https:// jumbo5566 .github.io/pro/rb/2024/04/17/rb016_025 .html (Download the dedicated test image and run it directly for reception: http s://drive .google.com/file/d /1RzKAeha6EW8e4WeDlxpYBMPwdu-GsVZJ/view ?usp=drive_link)
- Notes for prolonged continuous transmission: The bias voltage needs to be adjusted, and a range of 2.4–2.5V is safe. Additionally, adding a small fan for heat dissipation is recommended for better performance. For WSPR, there’s a simpler method that can be achieved using an RP2040 + GPS. Please search for “RP2040 GPS” for details

### ⭐⭐⭐⭐⭐ Works Good

Very nice product. BUT the instruction are not good, as well as the unreachable link to download the test file. I already connected it to my Radio berry, with the raspberry pi-4. and it works fine

### ⭐⭐⭐⭐⭐ Amp board working great with Pi4
*by J***Y on April 13, 2025*

I purchased the amp board before I noticed that it was not supposed to be compatible with the Pi4 board and required the Juice interface. I am glad I didn't see that in the description because I have it working perfectly with a Pi4, without any issues or modifications. The Pi4, Radioberry, and amplification board drive my Micro PA-50+ at 52 watts on 40m. I attached a couple of photos. I am using a voltage regulator to provide 8.4 volts to the amp board. I could use some help with the PTT interface. Anything I plug in automatically keys the Radioberry and amp.
