What band does ham radio use?
As for ham radio, the FCC has allocated a specific set of frequencies that start at the AM radio band at 1.6 MHz and end at 1240 MHz. This range includes two radio frequency bands, Very High Frequency (VHF), and Ultra HIgh Frequency (UHF), each of which has its pros and cons.
Which ham bands are best at night?
In general, the lower bands, 80 and 160 meters are best at night because of daytime D layer absorption. 30 and 40 meters typically work both night and day but daytime distances are limited because greater distances require lower propagation angles, which, in turn, mean longer paths through the D layer.
What bands can a general transmit on?
Generals can transmit on two new longwave bands that are below the AM broadcast band, as well as 10 HF bands that allow worldwide communications in a variety of modes. Many hams who go for the General class license do so because they want those HF privileges.
Which ham bands are USB or LSB?
When operating an amateur radio station using SSB, there are choices for upper and lower sideband. It is generally accepted that Upper Sideband, USB is used on frequencies above 10 MHz and that Lower Sideband, LSB is used in frequencies below 10 MHz.
Is 15 meters upper or lower sideband?
The higher frequency bands above the 30 meter band (20m, 17m, 15m, 12m, 10m, VHF, and UHF bands) utilize the upper sideband (USB), while the lower frequency bands below 30 meters (40m, 80m, 160m) use the lower sideband (LSB).
What ham bands are active during the day?
So, very rough rule of thumb:
- 20m, being in the middle, works to some extent day or night.
- Lower frequency bands work best at night.
- Higher frequency bands work best during the day.
- The farther from 20m you get in either direction, the more pronounced these effects are.
Which frequency is best for long range?
VHF and UHF Radios Compared – Which Is Best? VHF (136 – 174MHz) signals generally work best outdoors, giving a somewhat longer range for the same power output than UHF (400 – 470MHz).
Is upper sideband or lower sideband better?
It is generally accepted that Upper Sideband, USB is used on frequencies above 10 MHz and that Lower Sideband, LSB is used in frequencies below 10 MHz. Single sideband is available for use on most of the HF amateur radio bands, although some bands and frequencies are narrow and do not allow the use of SSB.
