Access to Amateur Radio for the Blind
Introduction
Blind accessibility to ham radio is largely hit and miss--excellent products come and go. Even when good products are available, it may be necessary to modify existing equipment.
Additional information on this subject and related topics can be found in back issues of QST and the other ARRL publications.
The ARRL has an extensive catalog of books and materials related to Amateur Radio.
