VisAir HF transceiver DDC/DUC 100W ATU
Description
A distinctive feature of the transceiver is the modern DSP data processing technology and information output to a large 7 touchscreen color TFT LCD display with a resolution of 800x480 with a capacitive touch screen.
Minimum signal delays for reception and transmission.
High-quality SSB signal shaping.
The user has the ability to adjust a large number of transceiver parameters.
Informative quality spectrum analyzer and waterfall
Today the transceiver of this class is the only one with such a high-quality spectrum analyzer with a waterfall.
The spectrum analyzer displays information in real time.
This allows you to get complete visual information about the correspondents in the analyzer's bandwidth.
The spectrum analyzer has a configurable visual depth and ranges from -150 dB to 10 dB, allowing the operator to tune the spectrum analyzer to suit the current receiving conditions.
Second survey receiver
An additional survey receiver operating in the 0.01 - 60 MHz band allows you to quickly observe other bands and stations in the first receiver's span.
Independent settings for span, modulation and filter width for the second receiver.
Audio player
The built-in audio player allows you to record the received stations and, if necessary, make a demonstration of the signal to the correspondent.
Signal pre-distortion
The signal pre-distortion function in the power amplifier reduces intermodulation distortion when transmitting in SSB and digital modes.
Built-in automatic antenna tuner and power supply
Built-in antenna tuner and power supply. will allow you to use the transceiver both in stationary conditions and in the field.
