500mw CW Transmitter - A very quick and easy way to get on the air is to build a "Michigan Mighty Mite" CW transmitter for 160, 80, 40 or 30 meters. It can't get simpler than this. It has very few parts, costs almost nothing, and it works! Cost estimate $10 by VE6WTF

40 meter QRP Transceiver - 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

A 80/40m DDS controlled QRP CW transmitter - JUMA-TX1 is a 5W CW transmitter for the 80/40m bands. Juha (OH2NLT) and Matti (OH7SV) have had high quality CW keying and a compact size as design goals for this project. No coils need to be wound to construct this transmitter!
