An economical dipole for simple QRP HF homebrew rigs

This Magnetic Longwire Balun (MLB) makes it possible to efficiently use a coaxial lead-in cable with all forms of longwires, T-forms or other types of wire antennas, without the need for an antenna tuner.

by Jim Stafford, W4QO appeared in QRP Quarterly, Fall, 2006

A frame antenna for the 80 meters band, built to be folded and to be easy to be mounted and dismounted. This antenna is suitable for indoor and QRP use, bandwidth is just 10kHz and should be observed a proper distance while transmitting due to high voltage.

The A QRP Club is a small group of Amateur Radio enthusiasts who enjoy building, operating and (mostly) talking about Low Power radio communications, equipment and systems.

The Atmel AVR Butterfly is a credit card sized board which contains an AVR MEGA169 processor, a six character LCD display, a five way joystick navigation switch, a piezo speaker, a 3 volt lithium battery cell for power and a few other odds and ends.

This project is based around the recent HF1 QRP transceiver by Ashhar Farhan, VU2ESE. The transceiver is an interesting SSB design with wide tuning range from 0-30MHz and should cover several amateur bands. The schematic for the transceiver can be found on the Minima mail list in this post with a PDF attachment

The KnightLites QRP Association is a world wide fellowship of low power (QRP) amateur radio communications enthusiasts founded in 1996, and is coordinated through the efforts of a small group of radio amateurs located in the Research Triangle region of North Carolina in the United States.
