VisAir

Go to the website of VisAir HF transceiver DDC/DUC 100W ATU


There are two versions of the transceiver VisAir for self-Assembly:
1. The analog version of the conventional SDR.
2. The digitization of the signal DDC.
Controller VisAir – versatile and can work in all variants. To it requires ( depending on option) DSP module (RX9CIM rx9cim@rambler.ru), the radio, the bandpass filters (see below), the power amplifier, LPF.
For DDC versions there are several radio RX/TX who can work with the controller:

  • HiQSDR, link
  • HiQSDR-mini link
  • вариант радиотракта DDC от (Rolin) Module-1. link

For all these radio RX/TX suitable DSP DDC version 2 RX9CIM. As George (RX9CIM) includes a new option Board DSP 96 kHz.
On the acquisition boards and the DSP is ready, at this stage it is necessary to apply directly to George.
For the analog option, you can use the radio channel from transceiver Tulip ( link) or a new radio channel VisAir on AD9958 (see below). For both options you need analog DSP transceiver Tulip. In the development of new reduced DSP Board for analog option.
