There is a speaker extension that works on 84 FM.  Has anyone tried it
out?  There must be something better.

I recommend the CARK-91H, which includes a privacy handset. I have had mine
for over two years, as I originally used it with my Nokia 6120, and I now
use it with my Nokia 6340i.

And for the external antenna that you would need.
