Hi all. Something occurred to me the other day: I was communicating with a deaf man via iphone as I do not know sign language. It got me curious as to whether or not there were any kind of exemptions to the CW requirement in the past for deaf people? I know that SSB would be a limited activity as well, but RTTY would seem to an activity that a hearing impaired person would be able to partake in. I have seen that there were deaf hams in the past (if i read it correctly) but was there a exemption made for those folks?
