Abstract

The invention discloses a virtual short wave narrowband receiver which comprises a bottom support and a vertical support fixedly installed at the left end of the top of the bottom support, and a plurality of receiver storage mechanisms are installed at the right end of the vertical support in a matched mode. Through arrangement of the receiver storage mechanism, placement of a single receiver is facilitated, so that damage to the receiver below due to stacking of a plurality of receivers is avoided; meanwhile, due to the fact that the multiple receiver storage mechanisms are arranged, and the number of the receiver storage mechanisms is adjustable, storage of the multiple receivers is facilitated; and a first rotating bracket is arranged, so that the receiver storage mechanism can be conveniently rotated, and the receiver in the receiver storage mechanism can be debugged.

Description

technical field [0001] The invention belongs to the technical field of digital communication equipment, and in particular relates to a virtual short-wave narrowband receiver. Background technique [0002] Shortwave communication is a kind of wireless communication, the frequency range is 3MHz ~ 30MHz, the communication distance is relatively long, and it has the characteristics of small channel bandwidth and large number of channels. Traditional receivers can receive fewer channels at the same time. The receiver is basically composed of amplifiers, filters, mixers and other components to amplify and filter the analog input signal and perform several frequency shifts or conversions. After sampling through the ADC, it is sent to a computer or DSP for further processing. In actual use, multiple receivers need to be debugged one by one. Generally, multiple receivers are stacked. Because the receivers are stacked, it is easy to press the receiver at the bottom; and multiple recei...
