I've had a similar problem, The headphone speaker element was the issue
with mine, it was picking up the RF like an antenna, try some ferrit bead
on the speaker line, I ultimately decided to change the headphones and that
solved the problem. There could be a feedback happening in the audio
amplifier which is why it doesn't happen on the kenwood.
My antenna is a vertical, somwhate close to the radio (30 feet) , my radio
is on the 2nd floor.
Have to take real care in this situation, a really good ground system is
required in my situation, Then I use the double sheilded LMR400 to insure
all the signal goes to the antenna, then I use line isolators at the ground
rod next to the antenna antenna, at the ground rod next to the house, and
then one after the amplifier. It may be over kill, but it pretty much
assures all the signal is at the antenna.
