How does the new HackRF Pro perform in practical tests? We compare it with its predecessor, the HackRF One, and analyze improvements in RF characteristics.

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 ...

In the old days, a shortwave radio was a major desk fixture. These days, you can get truly diminutive radios. However, most of them only have AM capability (that is, no simple way to receive ...

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) ...

Regarding Frank Foti’s SSB FM proposal as described in “A Method to Improve Conventional FM Stereo” (Radio World Engineering Extra, Oct. 13): The main computational load required to implement this ...

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 ...
