Europa-List: radio interference

[Richard Iddon <riddon@sent.com>]

I recently fitted an Xcom voice activated intercom to my Microair radio
setup.  I also invested in a pair of ANR headsets. Whilst I have reduced
the noise both my passenger and I hear very considerably, I am getting
some complaints from ATC units that there is now a lot of background
noise in my transmissions, (possibly interference from the alternator?)

Any idea's why this might be?
