I must say, I'm glad this thread is out there. I'm in my mid 30's, and as prior military and current law enforcement (thus the call) I have had my fair share of "bangs" next to my ears. The xyl is already complaining about my hearing, and I have to admit, my hearing isn't what it once was. I'm so happy the USMC gave us hearing protection hihi. I really haven't thought much about hearing aids but know I'm destined for them. I didn't realize until this thread that hearing aids were that advanced. One of my concerns was if I would be able to hear the radio in my retirement years. The reality is I may need hearing aids before retirement years. But I feel better about it now. I'm sure what ever aids I end up wearing will work perfectly with my future K5 or whatever K# we're at.
Maybe by then the technology will be so advanced that the K line will sense what we're thinking via ESP ( hint hint Wayne hihi) and convert it to CW and vice versa. But Gents, on a serious note, keep us younger hams informed on how hearing aids work, or anything else for that matter, because one day we'll be there as well, and at that point all we can do is pass down the knowledge we have to the next generation and keep the spirit of Amateur Radio alive. 73, Steve KS6PD On Wednesday, August 7, 2013, Al Lorona wrote: > Nope, sorry it was me that wasn't clear.
