by way of introduction, i have a small production
company focused on theatrical roadshows.

I have 18 Audio-Technica 7000 series wireless
microphones in the 728-740 MHz range. Recently,
the U.S. FCC auctioned off the 732-744 MHz range
to AT&T, with no clear winner in the 720-732 range.
with AT&T's investment in the billions of dollars,
it seems to me that I will lose use of most of
my range starting Feb 19, 2009, per the 'rule'.

I would like to retain my investment here,
if at all possible.

i wonder if anyone has had experience recrystalizing
wireless mics to alternative frequencies.

thanks,
-steve
