Here is what I do with good success.

For CW, I maximize RX EQ for my sidetone frequency. In my case, Sidetone is
800 Hz. RX EQ is 0 db for all bands except Band 5 (800 Hz) which I set at
+16 dB.

I just had my hearing aids adjusted. I asked for one program to bandpass at
800 Hz. Still evaluating if that is going to help.

Different people have different results.

Regarding hearing aids you may be interested in a product that can send LF
from K3 directly to your hearing aids.
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 been using this for about 6 years now and it is the best "headphones"
I have ever had! The price is about 3000 Danish kroner which is something
like 450 US $.

Kjeld,

I briefly mentioned that I have a "blue-tooth appliance" (without
explanation what it does).

My hearing aids support blue-tooth connection which requires a
separate remote (cost $450) that enables connecting to blue-tooth
accessories:  my i-phone5, for example.  The remote provides mic for
that connection.  With the remote came the "appliance" which has a
3.5mm phone plug and works with any audio source (like a stereo or a
ham radio).  Just plug the appliance into the headphone jack and you
hear the audio via blue-tooth.  Hearing aid batteries last about two
hours in use with blue-tooth vs lasting six days normal use.

To use the Phonak system would require buying new hearing aids
(current pair cost me $5200 two years ago), so that is not going to happen.

To the rest of the reflector, my apology for the OT subject.

For aids that include a telecoil (magnetic transducer), there are much
less expensive neck loops that plug into a headphone jack. For RF-based
hearing impaired systems that I designed and specified for public
spaces, I specified the Comtek NTC-102 neck loop. I see it listed at $95
from internet vendors. It has the obvious advantage of zero latency.

This is a relatively rugged professional product from a company based in
Salt Lake City. It's something that could easily be built -- the only
unknown is whether the loop is a single turn or multiple turns, and this
could easily be learned by winding one and trying it.
