Shortwave radios must compete with internet radios and televisions for their listener’s attention - a tough competition for it to win. Shortwave radio quality is weaker than domestic and some FM stations, even when there is a good reception. Shortwave radios are .

International Shortwave Broadcast Guide: Winter / 9th Edition. by Gayle Van Horn and Larry Van Horn | out of 5 stars 9. Tecsun PL Portable Digital PLL Dual Conversion AM/FM, Longwave & Shortwave Radio with SSB (Single Side Band) Reception out of 5 stars $ $ 98 $ $ Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to megahertz (MHz), with corresponding wavelengths of ten meters to one meter.
Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). Common uses for radio waves in the VHF. Shortwave radios are available in desktop and portable models. If you are planning on using the device in a stationary location and want the most powerful reception possible, consider a desktop model; however, if you are going to be using your radio while you’re traveling, a portable option is the obvious choice.
Shortwave Listening Tips: Listen to Asia and Australia in the morning and listen to Europe at night. No SW frequency operates 24 hours. You may not hear anything unless you are listening at the right time, or you may hear another language, or you may hear some other country sharing the frequency.
Shortwave - Shortwave Bands Use these frequency ranges when tuning around the shortwave bands to find international broadcasters. Only a very few stations operate outside these ranges. 49 Meter Band - kHz ( Mhz) 41 Meter Band - 31 Meter Band - 25 Meter Band - 22 Meter Band - Shortwave radio frequency energy is capable of reaching any location on the Earth as it is influenced by ionospheric reflection back to the earth by the ionosphere, (a phenomenon known as "skywave propagation").
A typical phenomenon of shortwave propagation is the occurrence of a skip zone where reception fails. With a fixed working frequency, large changes in ionospheric conditions may create.
Ultraviolet radiation lies between wavelengths of about nanometres (1 nanometre [nm] is 10 −9 metre) on the visible-light side and about 10 nm on the X-ray side, though some authorities extend the short-wavelength limit to 4 nm.
In physics, ultraviolet radiation is traditionally divided into four regions: near (– nm), middle (– nm), far (– nm), and extreme (below.

Paolo Boccotti, in Wave Mechanics and Wave Loads on Marine Structures, Overall Synthesis. The conclusion of this chapter consists of Eqns (), () and ().Equations () and () say that extreme wave loads on large isolated bodies are equal to the Froude–Krylov force multiplied by the diffraction coefficient.
Equation () may be used for calculating this. Over on the SWLing Post blog, author Thomas Witherspoon K4SWL has uploaded a new article titled "Software Defined Radio Primer Part 1: Introduction to SDRs and SDR applications".The article originally appeared in the June issue of The Spectrum Monitor magazine, which can be purchased online for $3 per issue.
The idea behind the article is to introduce people to SDR from a shortwave. The radio described here is a two band short wave receiver which is both very sensitive and very portable.
It receives AM, single sideband (SSB), and CW (code) signals over a frequency range of approximately to 12MHz. This includes 40, and 30 meter Ham bands plus several international short wave bands.
