What frequencies are in the HF band?

radio communications High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz.

Are aircraft radios VHF or UHF?

Air band or avionic radios are used in aviation as for both navigation and two way communication. If you are into aviation, you probably already know how important it is to have a radio while in the air. Air Band radios use VHF frequencies in the 108 MHz – 137 MHz range.

What is the most popular HF band?

20 meters – 14.0–14.35 MHz – Considered the most popular DX band; usually most popular during daytime. QRP operators recognize 14.060 MHz as their primary calling frequency in that band. Users of the PSK31 data mode tend to congregate around 14.070 MHz.

Do aircraft still use HF radio?

Modern aircraft now have an array of communication devices from the rudimentary HF radios of old to sophisticated satellite-based systems that enable us to talk almost as if we were on a mobile phone.

Is there a set frequency for HF radio?

The frequencies change daily depending on which has the less interferance (as you no HF radio isnt as clear as VHF) and so there are no set frequencies for different times of the day. Here is a list of HF frequencies and what they are used for over North Atlantic Crossings… (the 1st two of each listed are the most commonly used freqs!)

What are the VHF frequencies used in aviation?

The VHF frequency ranges used for aviation are: Frequency Allocation 108.000 – 112.000 MHz Aviation Terminal VOR and ILS Navigation 112.000 – 117.950 MHz Aviation VOR Navigation 118.000 – 136.975 MHz Aviation Communication

How old is the Aeronautical HF radio map?

Many thanks to Craig Fuller who shared this excellent Aeronautical HF radio map on the Shortwave Listeners Global Facebook page. Click here or here to download the map as a large graphic. Note that this map is 13 years old and somewhat out-of-date. Paul Jones kindly posted some frequency updates to the Shortwave Listeners Global Facebook page:

What are the radio frequencies for civil aircraft?

In the United States, VHF civil aircraft communications are placed in the 100 MHz band and allocated 760 channels within the range from 118.0-136.975 MHz. As a pilot, every frequency you talk on will fall within this range.
