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.

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. ### ⭐ No me funcionó *by J***P on December 4, 2024* No me funcionó, no amplificó y no hay documentación al respecto, se devolvió el artículo. ### ⭐⭐⭐⭐⭐ 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. ## Frequently Bought Together - AURSINC Radioberry Preamp Board V2, A Addition to Turn The Radioberry into a Small QRP Radio, Output 1.5W-3W for HF Power Ampfier (10W-100W PA), for Raspberry pi 4,4b - DHT Electronics Handheld Antenna Cable SMA Male to UHF SO-239 Female Connectors 6'' Pack of 2 for Amplifier --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/643763159-radioberry-preamp-board](https://www.desertcart.sn/products/643763159-radioberry-preamp-board) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-08*
