How long is a shortwave antenna?
The length of the antenna needs to agree with the length of the longest radio waves that you want to receive. Shortwave broadcasters use frequencies that are from about 50 to about 400 feet long, and an effective antenna needs to be at least one-fourth of that length — and one-half is much better.
Is shortwave AM or FM?
Marine radio uses FM except for long range marine that uses SSB a derivative of AM. And SSB is still the main transmit mode choice by a huge population of amateur radio operators. And most shortwave (SW) broadcasting is still AM. AM radio is talk radio, that is, news, weather, traffic, sports and opinion.
Why is AM radio so bad?
AM transmissions are much more susceptible than FM or digital signals are to interference, and often have lower audio fidelity. Thus, AM broadcasters tend to specialise in spoken-word formats, such as talk radio, all news and sports, leaving the broadcasting of music mainly to FM and digital stations.

Why is shortwave better at night?
As it turns out, the ionosphere reflects certain frequencies of radio waves. So the waves bounce between the ground and the ionosphere and make their way around the planet. … You can pick up some radio stations better at night because the reflection characteristics of the ionosphere are better at night.
What should I listen to on shortwave?
Specialized interests of shortwave listeners may include listening for shortwave utility, or “ute”, transmissions such as shipping, sailing, naval, aviation, or military signals, listening for intelligence signals (numbers stations), or tuning in amateur radio stations.
Why is AM radio bad at night?
The short answer to the question is: AM signals travel farther at night, so the FCC requires most AM radio stations to reduce power at night in order to avoid interference. … At night, as solar radiation decreases, the D layer dissipates, allowing AM signals to reflect back to the earth.

The decline in AM audio was due more to regulation than to method of modulation. One aspect of radio not understood by most listeners is the concept of occupied bandwidth, or the amount of spectrum that a station uses to transmit its signal.
Why do aircraft use AM radio?
Aviation voice radios use VHF AM. AM is used so that multiple stations on the same channel can be received. (Use of FM would result in stronger stations blocking out reception of weaker stations due to FM’s capture effect).
