Digital Switch Hits Glitches

Ahead of transition, viewers struggle to receive digital signals

Share

(Newser) – The big switch to digital TV may be less than a month away but many viewers are finding the transition anything but smooth, the Washington Post reports. Consumers are discovering that getting a converter box for older analog sets or buying a new digital TV doesn't always guarantee good reception. Many are expected to lose channels if they don't buy more powerful antennas.

To get all the channels they had before the switch, some viewers will have to buy pricey high-end converter boxes ineligible for the $40 government-sponsored coupons—or adjust the antenna for every channel change. All full-power stations plan to shut off their analog signals for good on February 17, although President Obama is pushing for the switch to be postponed.

Many viewers are expected to have to upgrade to high-end converter boxes or endlessly tinker with antennas to get all the channels they had before the digital switch.

what the price on the "pricey" boxes???? They are about 50 bucks down here, in Texas.....even if they were a hundred, we all have known of the switch for over two years......and if you can't manage to save a hundred dollars in two years, you have more things to worry about than watching TV.....and as for the reception aspect.....don't fall for the bs.......unless the TV stations are reducing their power after the switch, (a fact that I havent even heard about yet)....quality reception is either improved or unchanged by digitization.....if you had great coverage before the switch, you will continue to have it after the switch, the real difference is in the fringe areas.....digital information, that is corrupted by poor reception goes from great to poo poo with no in between, analog on the other hand, gets unreadable in many degrees, such as increasing snow or background static until it goes unusable, and the brain can compensate for a little of that to a degree. AND if the frequency, and polarity of the signal has not changed, the antennas effectiveness will remain the same, just ask any ham radio operator........and as an adjunct, a computer with a sound card can detect and translate morse code, PSK, MFSK, DIGIPAN, and a few other digital communication modes we "hams" use...waaaaaay below the effective threshold of simple voice communication......also, the better your antenna setup is the better results you will get....to put it in perspective, a satillite in geostationary orbit, is a few thousand miles line of sight over the equator......and they only put out 75 to 125 or so watts.....but with the right antenna, ......you have dishnetwork, direct TV and satillite internet...all from a measly 125 watts....but I wouldn't want to put up a parabolic dish designed for the TV frequencies....that sucker would be huge....kinda like the radio telescopes in "contact"...lol...but not quite that big..maybe just 20 footers...hope I wasn't too long winded, but I still havent touched as much info as I could Reply
