What is the 75 meter band? The upper portion of the band, which is usually used for phone (voice), is sometimes referred to as 75 meters. In Europe, 75m is a shortwave broadcast band, with a number of national radio services operating between 3.9 and 4.0 MHz.
As a consequence, Is 80 meters USB or LSB?
Also, What is the 50 MHz band? Six Meters (50-54 MHz) is known as "The Magic Band" to many of its fans, but the best description I ever heard came from a ham I worked during a frantic summer Sporadic-E opening: "This is a great band if you like having Mother Nature pull your chain."
Similarly one may ask, How do you use 2M band?
What are the 2m and 70cm bands?
2m- Good all around band for talking/chatting, but since its VHF, signal travel depends on what's in its way and the power output of the radio. 70cm- Good band, since its UHF its good to have in the city or around tall buildings or inside of buildings because its wavelength penetrates obstacles better.

What are digital modes?
Modes of digital transmission include multiple frequency shift keying (MFSK), wireless local area networks (WLAN), D-STAR, Codec2, and Automatic Packet Reporting System (APRS). On VHF bands, digital data modes have fewer restrictions on bandwidth.

What type of transmission is indicated by the term NTSC?
What type of transmission is indicated by the term NTSC? NTSC is the name of the standard used to encode colors in an analog fast scan color TV signal. If you ask a broadcast engineer, NTSC stands for Never The Same Color, because his job is to keep all the cameras looking the same.
What bands can Technicians use?
Techs can operate in CW (Morse code) mode on HF on the 40-, 15- and 10-meter bands on a narrow swath of frequency segments, as well as RTTY (radio teletype) and data on the 10-meter band.
What frequencies are in the 12 meter band?
They consist of 30 meters (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz) and 12 meters (24.890–24.990 MHz). They were named after the World Administrative Radio Conference, which in 1979 created a worldwide allocation of these bands for amateur use. The bands were opened for use in the early 1980s.
What is upper and lower side band?
In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, that are the result of the modulation process. The signal components above the carrier frequency constitute the upper sideband (USB), and those below the carrier frequency constitute the lower sideband (LSB).
Which bands are USB?
When single-sideband is used in amateur radio voice communications, it is common practice that for frequencies below 10 MHz, lower sideband (LSB) is used and for frequencies of 10 MHz and above, upper sideband (USB) is used.
