Morning Will
There seem to be two sorts one which is a component and is actually
connected in series with the wire and another that simply wraps around
the
outside of the cable those are the bumps on the PC cables (I think). I
would ask Yaesu for more information (make and model number and where in
the
set up it goes) I would guess round the headset cable to cut out the
stray
hum. Radios are strange things, the one that has always worked most
reliably for me has been my Icom handheld (Now 15 years old) with or
without
headset plugged in.
Good luck.
Pete
If it whines when away from the aeroplane you could take to whole setup
to
say Radio Shack and try the fix in the shop.

Thanks Pete
The radio is a self contained handheld. It has an adapter for use with
headphones. It works fine without headset but when you use the adapter
you
get the whine. The yaesu email help desk said use this ferrite choke
thing
(I now know what they mean) but not where to put it.. I am assuming that
the
ferrite choke would go on the headset cable?
Is it the same thing as you get round laptop power cables?

Hi Will
A ferrite choke is a coil of wire wound onto a ferrite rod. It has the
effect of passing DC ok but offering a high resistance to AC. If you
put it
in the supply line to whatever an Aviator Pilot is it stops the stray AC
getting through and kills the whine.
Regards
Pete

Has anyone "plumbed in" opne of these portables. I think I saw one
attached to a panel but I can't remember where.
Apparently it is not as simple as just connecting the headset and an
antenna
extension. You get a strong whine through the headset. I am told by
Yaesu
helpdesk that you need a ferrite choke. Not wishing to appear
ignorant.but
what the hell is a ferrite choke?
