    Software-defined radio (SDR) is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators, demodulators, detectors etc.) are instead implemented by means of software on a personal computer, lap-top, tablet or mobile phone.

    Software-defined radio using analog-to-digital converter (ADC) and some form of input RF cirquit (for SDR-receiver), or input-output circuit (for SDR transceiver).

    Because we landed on the moon recently?

    Maybe the OP just discovered it and wanted to share?? Hmm... :confused:

    Hi ABDO!....(CN8VO)...

    I believe in a few years, most of the transceiver will be using SDR. This is especially needed, for where most of the growth in ham radio, which is in suburban location. The noise that is inherent to these locations (Like mine), has a real disadvantage when working weaker signals. Using the current DSP's to eliminate the noise works to far down stream in the transceiver (Audio)....

    FYI (I worked for RTM!)

    Umm, No! SDR is not defined where the software is implemented, though it has been difficult for years to get hams to understand that SDR does NOT require an outboard Personal Computer for processing and user interface. We are finally seeing SDR radios with typical radio controls.

    Not every ham has an all-in-one radio. For example, my SDR is a combination of a SoftRock Ensemble II HF Rx and Linrad DSP software running on a Linux computer.

    Huh? I am making the point that SDR is not defined by using outboard PC"s for processing and/or user interface, as so many hams have misunderstood for years. Secondly that fully integrated SDR radios with typical ham radio controls are now in the market place.
