N4MW Code Practice Oscillator Museum

Middle age for "baby boomer" hams (like me) inspires various "nostalgia trips".  For me that means collecting artifacts which I encountered along the way in my ham career, beginning about 1965.  The code practice device collection, began in 1999, has grown to include a variety of morse code training devices and aids of many styles, currently including almost 400 items.
