I use a Phonak accessory called ComPilot that works with my Phonak
hearing devices. It hangs around the neck - the "loop" is the antenna -
to Bluetooth connect to my cell phone on my belt. It also has a 3.5 mm
stereo jack that can bring audio directly to the hearing devices, again
by Bluetooth. I'm sure that there are similar accessories for other
brands of hearing devices.

Re: K3 and hearing aids

I have been using the ComPilot for about 5-years. What a godsend. Never
use the headphones at all except when I have to operate ssb, because my
mic is on the headphones! ;-)

You can also use them on TV's, stereos, even on your PC, among many
other devices.

It wasn't about Mr. Hertz it was about the kilo that consistently is
written by a lot of folks with an upper case K, what I tried to focus
on. I suppose everyone knows why Hertz was given to the cycles per
second Phil was referring to...:-)

Re: ESSB

So, why is that? Most of the abbreviations for metric [i.e. SI]
prefixes with positive exponents are upper-case ... M [mega], G [giga],
T [tera], P [peta], X [exa], Z [zetta], Y [yotta]. *All* of the
abbreviations for prefixes denoting negative exponents are lower-case
... d [deci], c [centi], m [milli], u [micro, don't know how to get a mu
in email], n [nano], p [pico], f [femto], a [atto], z [zepto], y
[yocto]. When I bleed into the plasma machine each Fri, the blood
center measures my total serum protein in <somethings> per deciliter

Only da [deca 10^1], h [hecto 10^2], and k [kilo 10^3] violate this
pattern, which seems very un-metric. One would think the prefix
abbreviations would be paired letters, positive exponents get upper-case
and negative exponents get lower-case. How hard is that?

The prefixes themselves have some basis in real languages for smaller
[in absolute value] exponents ... I've always figured "milli" came from
a French word but since I speak almost no French, I'm not sure. I
struggled through 4 years of Latin in high school and I think I know the
origins of centi, deca, deci, and several others. Larger exponents in
absolute value really appear made up -- I mean, "yocto" and "Yotta"?

So, I generally camp on 1406100 daHz looking for folks activating
summits. Please call me if you're on a pointy part of the Earth.

One thing. The ComPilot manual includes:

"Persons using medical devices such as pacemakers
are not permitted to use this device."

Perhaps they're overly conservative, but worth a
discussion with cardiologist first.

Likely is conservative. I've had a pacemaker for 7
years and my KPA500 at full power seems to have no
effect on it -- nor on my Phonak hearing aid.
Using a 5 W HT also has no effect.
