- Qrp receiver homebrew. Here is a rig that provides a real challenge for the QRP home builder. It was originally based around an Arduino Nano but now uses an ATtiny3216. 18-21 Exotic circuitry and hard to find components aren't necessary if you want to build excellent performance into a home-brew SSB/CW transceiver: Careful design is the key. We simply take a lot of old ideas and put them into a sort of mental I’ve been working on a homebrew QRP CW HF transceiver for some time. Jun 18, 2025 ยท This was my first attempt at building a superheterodyne receiver so I was a bit nervous (although this video calmed me down). Homebrew RF Circuit Design Ideas "There is no such thing as a new idea. A classic circuit and a favorite in the QRP community. I believe that 45 years ago hardly anyone had receivers that were “adequate” for QRP contacts. It is impossible. When I was a novice, my first transmitter was a 7-watt homebrew for 40 and 80 meters. Only Technical stuff, and nothing else. The receiver takes inspiration from John Dillon’s (WA3RNC) TR-35. It’s completely scratch built and borrows design elements from several sources including the BITX40. com Kits QMX+ 160-6m multi-mode transceiver QMX multi-band transceiver kit QCX-mini 5W CW transceiver kit QCX+ 5W CW transceiver kit QDX Digital Transceiver QDX-M 5W Digital Transceiver Ultimate3/3S QRSS/WSPR kit U4B - Balloon tracker 50W Amp for QCX Ultimate relay-switched LPF kit GPS receiver kit QLG2 GPS receiver kit QLG3 10W HF Linear PA Low Pass Filter Band Pass Filter Si5351A Simple Receivers: More complex Receivers: Alternative microcontroller DDS and PC shortwave receiver: Two old shortwave receivers with the Wadley loop: Experiments with a passive crystal receiver: Receivers with tubes: Simple QRP transmitters: Simple QRP transceivers for portable use: QRP Transceivers for in the shack: Frequency counters for QRP More recently I have been using a receiver using an I. C. audio amplifier which is just a different version of the same receiver. What should I do to get started into home-brew HF RF devices? A QRP SSB/CW Transceiver for 14MHz -- Part 1 QST December 1989, pp. I know it worked OK, because I talked to my novice buddies around town. Low Profile, low power, Low QRM and High Fun! Also you are welcome to submit your own projects. qrp-labs. It is easy to achieve without relays at low power level. Mims III - it's a fast, easy and entertaining way to quickly grasp basic electronics and develop understanding of schematic diagrams. Do it your self, come and get simple circuits that you can build to enjoy real hamming. . Follow all the way to the bottom for a picture gallery, schematics, and source articles. A QRP SSB/CW Transceiver for 14MHz -- Part 2 QST January 1990, pp. I want to build a simple 40 meter CW transmitter and Receiver pair. 28-31 Homebrew amateur radio receivers, transmitters & transceivers. Take advantage of this 10-meter/QRP combo to get more miles per watt! Full QSK is beneficial during QRP CW work. QRP related The nice thing about stacking the boards is that I can shield the receiver from the transmitter and digital components. The bottom board houses the band-pass filters, receiver, and audio chain. HomeBrew HF High Performance Tranceiver (HBR2000) -- CW/SSB 160 to 10 meters, 6 watts output, full QSK on CW -- From Markus Hansen, VE7CA Homebrew SSB Transceiver for 60 Meters By Paul Alexander WB9IPA Cameron Tribe, KI7MNW recently posted his homebrew QRP transceiver on the Amateur QRP Radio group on Facebook.
