Greetings All:  I am a sighted ham trying to assist one or more visually
impaired teenagers eventually get into ham radio.  What are the best sources
for current study materials to hold a class.  One student is a good braille
reader but I am doubting that materials are available in braille.  Any
suggestions for materials and hold a class for the visually impaired in
general.  Thanks much...Steve Ferguson/N4PKJ
