[Elecraft] Bluetooth latency and CW reception

[Bob Nielsen, N7XY]

Like many of us of a certain age, I have started wearing hearing aids 
(actually I first tried one 20 years ago but since my hearing on one ear 
was still pretty good at the time I gave up on it soon after).  Now I 
have issues in both ears and am essentially deaf in one so I got aids 
with CROS technology to feed sound from both sides to my better ear.

Because of the technology involved in this, I was unable to get 
bluetooth capability in my hearing aid and have an adapter which 
receives bluetooth and  I have been told that it sends it to the aids 
with a very low power 10.6 MHz signal.  This works quite well but 
ordinary headphones aren't very comfortable when wearing the hearing 
aids and I would prefer to not have to remove them when operating.  I 
have been thinking about getting a bluetooth transmitter to connect to 
my K3S instead of using my headphones. However, I suspect that latency 
may be an issue and there might be an unacceptable delay between the 
keying input and the sidetone received by the hearing aids.  I N7XY'm 
also concerned that RF (especially on 30 meters) might saturate the 10.6 
MHz receiver inside the hearing aid.

Has anyone been able to use a bluetooth connection (such as bluetooth 
headphones) successfully on CW?
