The radio I'm referring to is the much loved AND reviled, and misunderstood "Pixie 2". The origins of this radio are familiar to the ardent QRP enthusiast. The original radio, called the "Foxx", was invented in 1982 by George Burt, GM3OXX. It was a simple, 5 transistor rig, that produced a … 16/01/2016 · The Pixie QRP transceiver kit is super-cheap but comes with some performance compromises. This video discusses crystal and ceramic resonator VXO circuits to add frequency agility and make contacts
5W HF PA kit SIMPLIFIED assembly instructions 1. Introduction This is a Power Amplifier kit (PA) for CW or FSK modes. The output power is approximately 5W in the middle of the HF frequency range, using a 13.8V supply. A single inexpensive IRF510 MOSFET is the amplification device. An unusual feature of this PA is the built-in facility for The original circuit was designed by Dave Joseph, W7AMX based on the earlier Micro-80 mini-transceiver by Oleg Borodin, RV3GM. Doug Hendricks, KI6DS drew a schematic and designed the original PCB layout for the Pixie 2 transceiver. The Pixie 2 first appeared in the June 1995 issue of the NorCal QRP Club's magazine called "QRPp". Additional
circuit trace printed on a circuit board acts like a coaxial cable and has very low inductance. With a PC board the same drive to the next stage can be nearly 100%, not 20%. If you have already developed your own method of making printed circuit boards, you may skip ahead. But if … “PIXIE” is a very small volume of simple 40 meter band micro-power amplitude telegraph transceiver, Despite it's small size and DC receiver limitations, it is capable of working several hundred miles when connected to a good 40 meter antenna.

The Pixie 2 is a small, versatile radio transceiver that is very popular with QRP (low power) amateur radio operators the world over. It reflects a history of contributions from amateur radio operators looking to build the simplest transceiver possible. At it’s core it is a crystal controlled (single frequency) sub 1-Watt QRP CW transceiver (High-frequency power meter circuit diagram with 1W 50 ohm dummy load And then connected to the high-frequency power meter with a dummy load reference circuit diagram (above), the “KEY” at both ends of the short-circuited, the headphones should be quick and silent, high-frequency power meter output.
It can be made in an evening and can be an ongoing project for anyone interested in building and I am sure it will give anyone interested in home-brew QRP projects hours of tinkering time.
