Build a Low Cost Code Practice Oscillator (#120)

Here's a really inexpensive, yet thoroughly serviceable Morse code practice device complete with a (rudimentary) key. This is only $18 postpaid in the US from the Four States QRP group. Build along with me and you'll have the perfect companion to our Saturday code practice sessions held at noon US Eastern Time (5pm UTC). Subscribe:    / davidcasler  .
