Notes:
Historically, there were local "Class A" frequencies (like A.M. radio's class C stations) to which only class A stations would be allocated & the other frequencies could not have a class A. According to the 1982 F.C.C. rules & regulations those frequencies were: 92.1, 92.7, 93.5, 94.3, 95.3, 95.9, 96.7, 97.7, 98.3, 99.3, 100.1, 100.9, 101.7, 102.3, 103.1, 103.9, 104.9, 105.5, 106.3 & 107.1.
Zone I in the U.S. includes all of Connecticut

Notes:
The class-A television class was created in 2000 by the FCC to allocate and protect some low-power affiliates. Class-A stations are still low-power, but are protected from RF interference and from having to move should a full-service station request that channel. http://www.fcc.gov/Bureaus/Mass_Media/Orders/2001/fcc01123.txt Additionally, class-A stations, LPTV stations, and translators are the only stations currently authorized to broadcast both analog and digital signals, unlike full-power stations which must broadcast a digital signal only.
The LPTV (low-power television) service was created in 1982 by the FCC to allocate channels for smaller, local stations, and community channels, such as public access
stations. LPTV stations that meet additional requirements such as children's "E/I
" core programming and Emergency Alert System
broadcasting capabilities can qualify for a Class A (-CA
) license. http://www.fcc.gov/cgb/consumerfacts/lptv.html
Broadcast translators, boosters, and other LPTV stations are secondary, unless they have upgraded to class A. Class A is still considered LPTV with respect to stations in Canada and Mexico.

- Canada protects all radio stations out to a signal strengthSignal strengthIn telecommunications, particularly in radio, signal strength refers to the magnitude of the electric field at a reference point that is a significant distance from the transmitting antenna. It may also be referred to as received signal level or field strength. Typically, it is expressed in...
of 0.5mV/m (54dBu), whereas only commercial B stations in the U.S. are. Commercial B1 in the U.S. is 0.7mV/m (57dBu), and all other stations are 1.0mV/m (60dBu). Noncommercial-band stations (88.1 to 91.9) are not afforded this protection, and are treated as C3 and C2 even when they are B1 or B. C3 and C2 may also be reported internationally as B1 and B, respectively. - Class C0 is for former C stations, demoted at request of another station which needs the downgrade to accommodate its own facilities.
- In practice, many stations are above the maximum HAAT for a particular class, and correspondingly must downgrade their power to remain below the reference distance. Conversely, they may not increase power if they are below maximum HAAT.
- All class D (including L1 and L2 LPFM and translator) stations are secondary in the U.S., and can be bumped or forced off-air completely, even if they are not just a repeater and are the only station a licensee has.

Historically, there were local "Class A" frequencies (like A.M. radio's class C stations) to which only class A stations would be allocated & the other frequencies could not have a class A. According to the 1982 F.C.C. rules & regulations those frequencies were: 92.1, 92.7, 93.5, 94.3, 95.3, 95.9, 96.7, 97.7, 98.3, 99.3, 100.1, 100.9, 101.7, 102.3, 103.1, 103.9, 104.9, 105.5, 106.3 & 107.1.

- For U.S. analog stations, the -TV suffix was required if there was a radio station with the same three- or four-letter callsign. Stations not required to use the -TV suffix could optionally request it if desired.
- All U.S. digital stations received a -DT suffix during the analog-to-digital transition. At analog shutdown, the FCC assigned each digital station the callsign its associated analog station had used. (with a -TV suffix if the analog station had one, without the -TV suffix if the analog station didn't have it) Stations could optionally choose to keep the -DT suffix. Most stations did not keep the -DT suffix.

- UHF all (14-69): 150 kW video; 15 kW digital
The class-A television class was created in 2000 by the FCC to allocate and protect some low-power affiliates. Class-A stations are still low-power, but are protected from RF interference and from having to move should a full-service station request that channel. http://www.fcc.gov/Bureaus/Mass_Media/Orders/2001/fcc01123.txt Additionally, class-A stations, LPTV stations, and translators are the only stations currently authorized to broadcast both analog and digital signals, unlike full-power stations which must broadcast a digital signal only.
