[Elecraft] Bluetooth latency and CW reception
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? 73, Bob N7XY __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Bluetooth latency and CW reception
I tried a few BT transmitters. No issue with interference, but the latency you are concerned about made it impossible to send at any speed. Works fine on SSB, but for me was not usable for CW and since most of my time is spent on CW I stopped using it. I know there have been a few members who claim to have found one that is better. Hopefully one of them will come in with a model and some data. -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

My hearing aid devices (Phonax Audeo) use an around-the-neck pendant adapter (Phonax ComPilot II) that does BT to and from my cell-phone but couples to the hearing aid devices inductively. It has a 3.5 mm jack that will feed external audio to the induction system as well. Standard 3.5 mm M-M patch cord from the headphone lack on the radio or the computer puts the audio sounds into my ears with no noticeable latency problems, as tested with my K2. They also make a BT adapter for across-the-room TV sound use but I have never tried it because I have no need for that. Enjoy hearing again. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Bluetooth latency and CW reception
Thanks for that reply Phil. Actually I also have Phonak hearing aids and a ComPilot II. I will give that a try after I get my new K3S installed within the next few days. I have only had the hearing aids for a few weeks but the improvement has exceeded my expectations. 73, Bob N7XY On 8/19/18 11:40 AM, Phil Kane wrote: On 8/17/2018 10:40 PM, Bob Nielsen, N7XY wrote: Like many of us of a certain age, I have started wearing hearing aids Welcome to the club.

Re: [Elecraft] Bluetooth latency and CW reception
I am also hearing impaired, but like to use a headset with microphone. My hearing aids just didn’t work with my favorite headset, but I discovered a work-around. I used the K3 audio receive settings to boost the frequencies required. For CW, I applied essentially a lot of gain to amplify my preferred sidetone frequency (~800 Hz) and for SSB I applied gain to frequencies required for speech recognition and attenuation to others ( a technique I borrowed from MFJ’s audio speech enhancer). With these adjustments, I can operate without hearing aids.
