VisAir - HF DSP Transceiver Standalone DDC DUC

Microprocessor-based data processing.

A distinctive feature of the transceiver is the modern technology of processing data in DSP and output information to a large 7 “touch-colored color TFT LCD display with a resolution of 800×480 with a capacitive touch screen.

Minimum delays in reception and transmission. Qualitative formation of SSB signal. The user can adjust a large number of parameters of the transceiver.

Informative quality spectrum analyzer and waterfall

To date, a transceiver of this class is the only one having such a quality spectrum analyzer with a waterfall. The output of the information of the spectrum analyzer occurs in real time. This allows you to get full visual information about correspondents in the bandwidth of the analyzer.

The spectrum analyzer has a configurable depth of the visible region and is in the range of -150 dB to 10 dB, which allows the operator to adjust the spectrum analyzer to the current reception conditions.

Second survey receiver

An additional survey receiver operating in the band from 0.01 to 60 MHz, allows you to quickly monitor other bands and stations in the band of the first receiver. Independent settings for the viewband, the type of modulation and the width of the filter for the second receiver.

Audio Player

Built-in audio player, allows you to record the received stations and, if necessary, make a signal demodulation to the correspondent.

Signal Predication

The signal pre-emphasis function in the power amplifier reduces the intermodulation distortion during transmission in SSB and digital communication modes.
