Here’s a collection of NASA sounds from historic spaceflights and current missions. You can hear the roar of a space shuttle launch or Neil Armstrong’s “One small step for (a) man, one giant leap for mankind” every time you get a phone call

While roaming around the upper part of the 40 meter Ham Band in the LSB MODE, I recently overheard a conversation between a roundtable group. I listened for a few moments and then heard one of the Hams who was most likely new to Ham Radio, ask one of the others in the group to give him a signal report.

In this episode we build a BM and do some experiments with it to understand how it works. A BM is always in the TX SSB signal path.

So I wanted a headset/boomset for use with my ham radio equipment. I knew I wouldn't use it all that frequently so the high prices for the Heil products didn't make a lot of sense to me.

This page is to share what I and some others have learned about several items of surplus radio gear suitable for use in the Amateur Radio service. Many models of surplus commercial and military radio equipment are desirable because of the higher physical and electrical characteristics this equipment is built to.

I have been actively using, installing, and repairing transceivers for the 11 meter band, or CB Radio, as it is best known, since getting my first real radio in 1970 (not to mention using CB walkie-talkies since the 60's).

The nomenclature of the radio hobby can be bewildering! The following is a list of some of the more widely used (and confused!) terms and abbreviations found in ham radio, shortwave radio, and scanner monitoring.
