The generation of single sideband (SSB) signals first came to my attention via ham radio back in the early 1960s. My call was then and still is WA2IBH. The best phonetic I had for that call sign was ...

AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon microphone is ...

The upper or lower sideband of a carrier frequency that is amplitude modulated. To save power, the carrier and one of the sidebands is eliminated, leaving only a single sideband for transmission.

This year, we recognize John R. Carson for two major contributions to communications technology: the invention of single-sideband (SSB) modulation and his rule for estimating frequency modulation (FM) ...

There was a time — not long ago — when radio and even wired communications depended solely upon Morse code with OOK (on off keying). Modulating RF signals led to practical commercial radio stations ...

Many of today’s experienced engineers got their start in electronics through amateur, or “ham,” radio. (Many theories exist over the origin of the term “ham radio,” but there is no consensus.) Over ...
