Providing quality products to Amateur Radio Operators, morse keyers, portable paddle.

Free Donwload of the PDF file of ITU and CQ zones of the world, made available by Icom America

The terminal program for CW-operators. You can transmit both from the keyboard and from a paddle connected to game or LPT ports. You can also operate in paddle iambic mode. Control of the transceiver (PTT and CW keying) is made through one of the COM or LPT ports. CwType can integrate with AALog software

Tombone VHF antenna for 146 MHz ad designed by YB8EIP

A quarter wave vertical end-fed antenna for the 40 meters band. As all vertical antennas, also this aerial requires a good earthing system. In this project the ground is composed by twelve 4, wires buried in the lawn by using a spade to create a slit to drop the wire into.

How to build a beacon keyer for 28 MHz using an old CB Radio transceiver, by Tom Sevart

CW decoder project that automatically adapts itself to the CW rate and may be employed for learning purpose substituting the traditional tone generator and offering the capability of displaying the keyed code.

This note describes a relatively small, but efficient, loop antenna initially created for portable operation. With suitable modifications, it can be adapted for fixed station use. In this age of CC&Rs, an antenna similar to this may very well be the answer to your problems. Have a look, be inspired, get out the torch / soldering iron and create your own version!

A vertical antenna specifically designed to work with the 80 meter CW beacon keyer

This simple 30m QRSS beacon is built entirely out of junkbox parts, the only component purchased specifically for this project was the 10,140kHz crystal. Hans Summers' 30m QRSS beacon project emphasizes simplicity and low cost, built almost entirely from reused parts. Key components include a 10,140kHz crystal, a 2N3904 transistor from a broken DVD player, and an ordinary LED used for frequency shift. The oscillator is stabilized in a polystyrene box, with power amplification driven by recycled copper PCB. Output power peaks at 360mW, and a custom 50-ohm dummy load manages heat. Though aesthetically unconventional, the beacon works effectively, fulfilling the project's low cost aim.
