We are less than a year away from a big transition. On February 17th,
2009, a big portion of the analog spectrum will end. You may have heard
about this on TV or radio. Unfortunately, there is a lot of
misinformation going around.

There are 2 issues in play.
1.
The analog frequencies for TV stations will expire. The stations will
still exist, but they will only broadcast digitally. This will
ONLY affect people who get their TV
SOLELY through an antenna. If you watch TV via cable or satellite, this will
NOT affect
you. Don't believe your provider if they tell you otherwise (now they
might be changing some of their equipment at the same time, but that's
a separate issue). If this change affects you, you will need a
converter to take the digital signal coming though the air and convert
it back to analog for your TV. Go to the
FCC website
to get a coupon for the converter. Currently all Chicago area (and
Rockford and Milwaukee) stations are broadcasting both in analog and
digital. So next year, they will just shut off the analog and keep
broadcasting digitally.
As a side issue, digital does not
necessarily mean HDTV. All HDTV is digital, but not all digital is HDTV
(like squares & rectangles). Almost all shows are now recorded in
high definition. Pretty much just some random reality shows and
cable/satellite only shows are not in high definition. And those are
planning to switch soon.
2. The other issue is our wireless
mics. Currently all wireless mics use unused TV frequencies to operate.
For instance we don't have a TV station 28 here. So that is one of the
frequencies that we use for our wireless mics. If we moved these
systems to Lubbock, Texas, we would be in trouble. Their ABC station is
channel 28. So churches down there use wireless system with other
channels. However, once these analog frequencies get shut off next
year, a big change happens. TV channels 52-69 will no longer be
available. They are being auctioned off right now to the highest
bidder. Companies such as Verizon, AT&T, and Google are bidding
billions of dollars for the right to sell devices that use these
frequencies. Not only will it be bad to use wireless mics in this
spectrum because of interference, but it will be illegal. Thankfully
none of our wireless systems are in this spectrum. One of the churches
around here will have to replace $30,000 worth of equipment that is
within that spectrum. They will basically become boat anchors.
The
FCC also wants to sell off the "white spaces" in between the new
frequencies to these companies. This would be horrible. If this
happens, our channel 28 wireless systems would be unusable. So would
all wireless systems. Thankfully Shure and all the other wireless
manufactures are talking to Congress about this and the impact it would
have on our nation (all TV & film productions, Broadway, live
sporting events, political conventions, etc all use wireless systems).
So that is the issues in a nutshell. I hope this wasn't too confusing. If you have any questions, please ask.
