This project define a simple shortwave all mode and general coverage Software Defined Radio receiver. - gcallipo/RadioDSP_SDR_RX ...

Many of the less expensive shortwave receivers have no squelch circuit and continue to emanate noise when no usable signal is coming in. Fortunately, they normally have an LED which lights to indicate ...

The Silicon Labs Si4735 is a single-chip solution for receiving AM, FM, and shortwave radio. With a bit of hacking, it even supports single sideband (SSB). All you’ve got to do is provide it … ...

Article Shortwave Monitor This broadband AM receiver enables you to ‘monitor’ the shortwave radio band. The circuit has been deliberately designed to have low selectivity and is most sensitive in the ...

In the developing world, however, the need for shortwave radio remains, but listeners do not have the money to buy expensive DRM receivers. “Unless a company comes along with a DRM receiver that can ...

AM/FM/SW Active Antenna This circuit shows an active antenna that can be used for AM, FM, and shortwave (SW). On the shortwave band this active antenna is comparable to a 20 to 30 foot wire antenna.

This paper presents an AM receiver implemented in a flexible a-IGZO TFT technology. The circuit consists of a four-stage cascode amplifier at the RF input, a detector based on a source follower, and a ...
