Class A TV stations are former LPTV stations that have certain interference protection rights not available

to LPTV stations. These stations are technically similar to LPTV stations, but unlike LPTV stations must

air at least three hours of locally-produced programming each week and comply with most of the non-

technical regulations applicable to full-power stations. Approximately 600 licensed Class A TV stations

are in operation.

A TV translator station rebroadcasts the programs of a full-power TV broadcast station. Translator stations

typically serve communities that cannot receive the signals of free over-the-air TV stations because they

are too far away from a full-power TV station or because of geography (such as uneven terrain or

mountains). Many of the 4,700 licensed TV translator stations operate in mountainous or more remote

areas of the country.

There are several ways to determine whether the broadcast stations you view over-the-air (with a rooftop

antenna or “rabbit ears” attached to your TV) are LPTV, Class A or TV translator stations. Class A

stations are required to visually or aurally identify their stations with their community of license and call

sign (that includes the suffix “-CA” for Class A) at sign on, sign off, and on an hourly basis. LPTV

stations also must regularly identify their station call sign. When locally originating programming, they

must visually or aurally identify their call sign and community of license at sign on, sign off, and hourly.

LPTV call signs may consist of four letters followed by the suffix “-LP” (for low power) or, alternatively,

five characters beginning with the letters K or W followed by two numbers (their operating channel) and

two additional letters. Also, some TV translators are identified by the full-power TV stations whose

signals they rebroadcast. Further, LPTV, Class A, and TV translator stations may regularly broadcast

information as to their status, and may include information regarding the DTV transition.

While the February 17, 2009 deadline for ending analog broadcasts does not apply to low-power, Class A,

and TV translator stations, the FCC will require these stations to convert to digital broadcasting some time

thereafter. Nearly 2,000 of these stations have been authorized to construct digital facilities and some are

broadcasting in digital already.

If you have an analog-only television that receives free over-the-air programming (with a roof-top antenna

or “rabbit ears” on the TV), you will need to purchase a digital-to-analog converter box in order to watch

digital broadcast television. Each U.S. household is eligible to receive two $40 coupons to be used toward

the purchase of two digital-to-analog converter boxes. The National Telecommunications and Information

Administration (NTIA) is administering the coupon program. (Please note that these coupons will expire

90 days after mailing). More information can be found by calling 1-888-388-2009 (voice) or 1-877-530-

2634 (TTY).

If you purchase a digital-to-analog converter box to watch digital broadcasts on an analog TV and also

wish to continue watching analog LPTV, Class A, or TV translator stations, you should purchase a

converter box with “analog pass-through” capability, which allows analog broadcast signals to pass

through the converter box to be tuned by your analog TV. NTIA’s TV Converter Box Coupon Program

has certified converter box models that have analog pass-through capability. A current list of coupon-

eligible converter boxes is available. The converter box models that have analog pass-through capability

are noted on the list with an asterisk next to them. In addition, NTIA will mail a list of current coupon-

eligible converter boxes, noting with an asterisk those that have analog pass-through capability, to each
