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?
