Blue Tooth

After many decades of Ham Radio (licenced 1953) my ears are showing lack of
sensitivity and signal to noise! My friend showed me her new hearing aid
and it is Blue Tooth capable, her cell phone connects directly to her
hearing aids. It would be absolutely marvellous if the K3 could do the
same. I could sit at my desk copying CW without headphones or loudspeaker.
What about it Eric and Wayne?

http://www.blucomm.com/blucomm.jpg I have heard they can make custom
connections. Might be worth checking out.

I received a Bluetooth headset as a gift, and found I couldn't use it with my radio because of the delay. It made it impossible to send CW. There are audio-to-bluetooth adapters, but if you buy one for your rig you might want to make sure you can return it if there is an unacceptable delay.

All hearing aids in the UK and most of Europe include an Audio Hearing
Loop facility, called variously AFIL or Telecoil. I understand though
that these are relatively rare in the US - http://www.hearingloop.org/
is a site your side of the pond trying to change the situation. Loop
systems are widely used in churches (I think it is now a UK Disability
Act requirement), shop counters and other public places. Many people
also use them in their homes with loop amplifiers connected to their
TVs, suitable boxes to do this are widely available.

And of course many radio amateurs use them, just connect the audio into
a loop amplifier and have a small loop in the shack, or in the most
simplistic way just drive the loop from the rig speaker output.

Don't think there are any bluetooth hearing aids in the UK, but hearing
loops are universal.

Re: Blue Tooth

One matter that I think should be considered is the frequency profile of
one's hearing loss. A bluetooth headphone set will not normally provide
for the frequency compensation that your audiologist has built into your
hearing aids. Putting a headphone set over the top of hearing aids will
generally result in feedback howling. An in-ear bluetooth headphone can
be very comfortable, but with hearing aids removed, will not provide
frequency compensation unless you add a filter circuit between the audio
signal and the bluetooth transmitter.

If your hearing aids are bluetooth enabled, then for a few dollars, you
can buy a bluetooth transmitter that plugs into any audio output. The
transmitter battery is re-charged from a USB port on a computer.

Hope this helps

Get a Jabra A210 bluetooth adapter which was designed for older cell phones
without Bluetooth. You will have to convert the 2.5mm jack to different
dimensions. Plug the Xcvr headphone out to the Jabra and synch to your
hearing aids.

They can still be found on eBay.

This will also work on the microphone side for two way hands free, requires
a Bluetooth headset with boom mic.

Re: Blue Tooth

Oticon hearing aids (made in Denmark) offer an accessory that transforms
Bluetooth RX into the format used for wirelessly linking the right and
left hearing aid. With that adapter, you can hear a cellular phone (via
BT) in both ears instead of one. You can attach an auxiliary adapter to a
stereo output (TV, stereo RX, K3) and hear it in the hearing aids.

At some point, I'm going to get these adapters and dispense with my
headset (hi).

Re: Blue Tooth

In reply to this post by Mike Scott-7

Sorry for the OT bandwidth but this subject keeps coming up.

Two years ago I bought a Jabra bluetooth adapter and headset (with boom mic)
to use with my K3. I used the
equipment that was featured in a QST article on the subject a couple years
ago. It sort of worked but was a big hassle to set up .. and it was
necessary to go through a setup procedure every time I used it. The main
problem, though, is that bluetooth technology has been developed for use
with telephones and computers. I spent more than a hundred dollars on my
adapter and headset and found it to be very cheaply made. Even worse .. the
adapter has a battery saving feature that automatically shuts it down after
a minute or so when it does not detect any audio which makes it almost
unusable for typical ham radio use. I gave up in disgust. Maybe some
bluetooth equipment is
better now .. I don't know .. but I'm not going to give it another try.

I sure would like some sort of RF link for my headset with boom mic. If
anyone has a good idea along those lines I would like to hear it. I have
looked for commercially made equipment but all I can find is headphone-only
RF links and handheld mic RF links .. all fairly expensive and not adaptable
to a headset with boom mic.

Dear Max,

The Danish company Phonak are selling a device under the name of TVLink
which plugs into the line out, Scart, headphone or external speaker
connector and from it's console sends in stereo to your hearing aids. I have
not tried it yet - so I cannot say anything about the possible delay which
is mentioned by Liegh in another mail. The price is 3000 DKK.

Re: Blue Tooth

I tried those when I fist got my hearing aides for listening to music at work.
They use voice coil coupling and are definitely NOT high fidelity.

Re: Blue Tooth

No, Tom, they are NOT audio loop devices, but true bluetooth, and only
work with modern bluetooth hearing aids. And I am not sure what sort of
HiFi you expect, but if you have a hearing aid it is probably academic.

Full information at:
http://www.phonak.com/uk/b2c/en/products/accessories/communication/icom/
overview.html

All in English. Confusingly they call it the iCom, which is nothing to
do with the other company...
