• The Tecsun PL880 is a world band radio receiver with FM stereo. In addition, it can receive AM, SW, LW and SSB radio waves. The reception range can go from as little as 64 to 108 MHz. This makes it suitable for worldwide FM signal reception. It has various buttons that make the portable radio comfortable and easy to use.
• 'Long distance reception' on the AM band is dependent on many factors, not just the radio. The antenna is also a big part of the picture (loops are often used here, unless you are very well endowed with lots of land for an antenna), as well as understanding how the AM band works, and when and where to listen.
• View Distance Records here - Last updated 11 September 2020. Notes: Frequency bands include Micrometer Radio (300 to 3000 GHz) and Light (3 to 30,000 THz).. Propagation modes are tropospheric refraction and ducting (including line-of-sight paths), divided into in three categories: Tropo (A) (tropospheric modes across the Atlantic, Caribbean, and Gulf of Mexico); Tropo (C) (tropospheric modes ...
• Radio wavelength is the distance between crests of a wave. The product of wavelength and frequency is a constant that is equal to the speed of propagation. Thus, as the frequency increases, wavelength decreases, and vice versa. Radio waves propagate at the speed of light (300 million meters per second).
• Dec 11, 2015 · Useful daytime AM service is generally limited to a radius of no more than about 100 miles (162 km), even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called "skywave" propagation.
• At typical heights when your radio is being held to your head, the horizon is only 3 miles away (and if the other radio you are communicating with is also, say, 5.5 ft above ground level, then the total distance between you should be under 6 miles for line of sight conditions).
