 (They are much cheaper elsewhere - around $65/pair at Sams Wholesale as I
recall - usable, real-world range is much less than that also.)

  The consensus in rec.motorcycles seems to be that the combined mic/earphone
units are totally unusable on a motorcycle.   In addition, recent discussion
from those that use them indicate that the range on the 49MHz FM units are
totally unsuitable in motorcycle applications in general.  In particular, the
VOX (voice-activated mics) are pretty useless in the high-ambient-noise
enviroment of a motorcycle, primarily due to wind noise.  The only exception
to this sometimes is use on fully (and I mean completely) faired mototcycles
like the long-distance luxury tourers.

  As an alternative, many people have spoken highly of using simple CB units
on a motorcycle.  I am in the process of fabricating a headset to build into
my helmet, by mating a new mic and headphone arrangement to a matching mic
plug and external speaker plug on the $39 Uniden CB radios I bought at Service
Merchandise.  By the time I finish buying the parts, the antenna, etc..,
including the tank bag for my wife's bike (to mount her CB in), the cost will
have exceeded the cost of the FM units by quite a bit, yet I will have the
advantage of longer range and many more channels, plus the ability to
communicate with the more common CB radio crowd, if I so choose.

  For further opinions, perhaps a posting in rec.motorcycles would be more
appropriate, or at least cross-posted there.
