Is HF radio still used?
This skip effect allows long range transmission beyond the horizon and even globally. While propagation can be affected by various atmospheric conditions, HF radio remains a consistently reliable performer in a surprising variety of conditions. Cruising is a community.

Is HF ham radio AM or FM?
Single sideband (SSB) is the most popular mode of voice transmission on the HF bands in ham radio. (FM is mainly used above 50 MHz.) The mode got its name from a key difference from the older mode, AM, which is used by AM broadcast stations and was the original voice mode that hams used.
What is HF ham radio?
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).
What frequency is HF?
High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz.
What HF 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.
How do I extend the range of my ham radio?
To boost range, get to an elevated area and use the radio there. Use a repeater – Signal repeaters can help extend range. A repeater receives and re-transmits the signal from your radio with increased power.
Does a longer antenna get better reception ham radio?
In a nutshell, the longer the antenna the more signals it can catch. So for your truck trying to catch the wavelengths of your radio station, typically what is referred to as a quarter-length antenna is best, so that’s about 32 inches long.
