Better documentation in English would be a plus. ### ⭐⭐⭐⭐⭐ Will buy from again *by T***B on February 15, 2020* Great product ### ⭐⭐⭐ Good troubleshooting practice. *by W***S on November 19, 2019* The molex connectors are wired backwards! Dont rely on the color of the wires when connecting power! I got a big puff of smoke, and now i need a new voltage regulator before I can assess if further damage occurred. Also, the photocopied instructions contain so many smudges and artifacts that they are almost unusable! There were no instructions on how many turns of wire are needed on the inductors. I later found on the internet that 11 turns for the black one and 16 turns for the colored one (by the antenna) are needed. Board quality is good and dense. I would like to see an option for a BNC or SMA connector for the antenna. ## Frequently Bought Together - HAM Radio CW Shortwave Transmitter Receiver Forty-9er 3W CW Shortwave Radio Transmitter Receiver Telegraph DIY Radio Kit - LJJDSLYU S-Pixie CW QRP Ham Amateur Shortwave Radio Transceiver 7.023 7.050 Mhz DIY Kits with Transparent Acrylic Shell - 1-30MHz Manual Antenna Tuner Kit for Ham Radio QRP DIY Kit --- ## 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.co.th/products/80916958-ham-radio-cw-shortwave-transmitter-receiver-forty-9er-3w-cw](https://www.desertcart.co.th/products/80916958-ham-radio-cw-shortwave-transmitter-receiver-forty-9er-3w-cw) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-30*
