Rudy, you may be making this more complex than it needs to be.  Does
your hearing aid have a GOOD T-coil?  (If not, junk it and get one
that does.)  Why try to put all that hardware in your helmet?  Use a
neckloop and couple the output of the FM receiver inductively to your
aid.  The FM receiver could be anywhere under your jacket or whatever
you may be wearing.  If it is unstable, just use more velcro.

The neckloop could be worn conventionally (around the neck), or if
you need a tighter coupling tape it around the helmet at ear level.

I've used effective but expensive FM systems from Telex, Williams,
Phonic Ear and Audex.  But if you would like something that works
about as well for 10% of the cost, try the FM wireless mike that
Radio Shack sells for use with video camcorders (part #32-1226).
The receiver has a monitoring jack that can drive a neckloop.

Neckloops can be purchased for $40 to $80 from most any of the ALD
makers, or you can make your own with about $2 worth of stuff from
the hardware store.

... Jack.
