This semi-homebrew QRP (low power) CW transceiver is based on the ARK-40 transceiver kit, by S&S Engineering. With its built-in CW keyer and 5 watts of power, the basic ARK-40 transceiver is an outstanding 40 meter CW performer

This homebrewed antenna tuning unit also incorporates a 50-ohm QRP dummy load, power meter (1 or 10 Watts full scale), and SWR meter

This is a C-L-C type tuner with a reflected power indicator. Tuning is done for minimum reflected power.

This describes a homebrew End-Fed Half-Wave (EFHW) antenna for low power SOTA, Parks and Field Day events. Made with readily available materials, it offers a resonant antenna in 40/20/15/10m bands without requiring an antenna tuner. The 19.8m long radiator wire in an inverted V configuration achieves VSWR below 1.5:1 for voice. CW users might need to adjust the length. Details include materials list, fabrication of the end insulator, and the 49:1 impedance transformer construction with a circuit diagram.

Learn how to build the PAC-12 Antenna, a multi-band portable vertical designed by long-time antenna aficionado James Bennett, KA5DVS. This award-winning antenna is easy to homebrew using common components from a hardware store, with replaceable loading coils. Perfect for hams looking for an efficient and portable antenna for field trips. Discover the design and construction plans, as well as the author's journey to create the ideal travel antenna for lightweight and packable use.

The Homebrew uSDX SDR TRX is an experimental transceiver primarily designed for CW and Digital modes due to limitations in meeting FCC requirements for SSB. Developed from the QRP Labs QCX, it incorporates advanced SDR features while utilizing an 8-bit ATMEGA328P. The µSDX community fosters open-source development with various design streams and versions, encouraging collaboration and sharing among enthusiasts.

Tubes are a dying technology. All modern transmitters, even high power ones, do work with transistors and other semiconductors. But many fondly remember their first homebrew transmitter and its hard to forget warm glow of a vacuum tube. The Station QRP website is especially for you to come into touch with tube technology. This site is all about handcrafted QRP AM tube transmitters.

This article details the design and construction of a compact 20-meter QRP SSB transceiver by Pete Juliano, N6QW, measuring just 2 x 4 x 2 inches—small enough for a shirt pocket. Inspired by a 1963 QST design and refined from a prior version, it employs bilateral circuits, a 4.9152 MHz homebrew crystal filter, switched-crystal VXO for 60 kHz coverage (14.160-14.220 MHz), and standard components like ADE-1L mixers and IRF510 PA for 1W output. Key innovations include a double-sided PCB skeletal frame for shielding and isolation, Vectorboard sub-assemblies, and ultra-miniature relays. The bilateral receiver/transmitter shares stages, omitting AGC for simplicity, while a W3NQN LPF and optional 10W external amp enable DX contacts. Tune-up focuses on crystal matching and bias for linearity. Videos on YouTube demonstrate performance, confirming excellent stability and audio. Total cost nears $100, prioritizing portability over features like CW.
