HOW CAN I DETERMINE IF AN OUTDOOR ANTENNA
WILL HELP?
While inside your normal listening environment, tune in a rela-
tively weak shortwave signal. Staying tuned to this signal, step
outside and away from your building. If the signal strength
increases significantly, an outdoor antenna will help considerably.
If there is little or no improvement in signal strength, an outdoor
antenna will help; however, the amount of improvement will
depend on the type of antenna used. If you have questions about

Mean Time (GMT), World Time and Zulu Time.
Just what is UTC? It is the time in Greenwich England with no
correction for daylight savings time, and is always stated in 24
hour format. In North America, UTC is ahead of our local time, 5
hours EST, 6 hours CST, 7 hours MST, 8 hours PST; one hour
less during the months of daylight savings time. So, if a broadcast
starts at 20:00 hours UTC, this correlates to 15:00 hours (or

GETTING STARTED WITH SINGLE SIDEBAND (SSB); MARITIME & AERONAUTICAL WEATHER AND COM-
MUNICATION FREQUENCIES; HAM RADIO COMMUNICAATION FREQUENCIES; TIME SIGNALS
High end shortwave radios, such as the Grundig YB400PE, have
a feature called SSB, a highly efficient way of electronically
processing transmitted and received signals for two-way commu-
nication. Examples of this are amateur radio (hams), maritime, and
aeronautical communication. Either upper side band (USB) or
lower side band (LSB) can be used....

Below are some selected frequency ranges on which SSB communication can be found. All frequencies are shown in Kilohertz.
