It performs DDC / DUC conversion (digital frequency shift down or up the spectrum) - by analogy with a direct conversion receiver. The I and Q quadrature signals from the conversions are fed to the STM32 microprocessor. It filters, (de) modulates and outputs audio to an audio codec / USB. It also handles the entire user interface. When transmitting, the process occurs in the opposite order, only at the end of the chain there is a DAC, which converts the digital signal back to analog RF. -Specifications -Receiving frequencies: 0 MHz - 55 MHz -Transmission frequencies: 0 MHz - 30 MHz -TX power : 20W -Modulation types (TX / RX): CW, LSB, USB, AM, FM, DIGI -Preamplifier -Adjustable attenuator 0-31dB -Band pass filters -ADC dynamic range (12 bit) ~74dB -Supply voltage: 13.8V (overvoltage and polarity reversal NOT protection) -Consumption current when receiving: 350-800mA (DC-DC or linear) -Current consumption during transmission: ~5А -Transceiver Features -Panorama (spectrum + waterfall) up to 48 kHz wide -Panorama tweaks and themes -Adjustable bandwidth: HPF from 0Hz to 600Hz, LPF from 100Hz to 20kHz -Integrated SWR/power meter (HF) -Automatic and manual Notch filter -Switchable AGC (AGC) with adjustable attack rate -Range map, with the ability to automatically switch modes -CAT virtual COM port (FT-450 emulation, RTS - PTT, DTR - CW) -USB operation (audio transmission, CAT, KEY, PTT) -SWR Graphs -Spectrum analyzer -Equalizer TX/RX, reverber -AGC takes into account the characteristics of human hearing (K-Weighting) -TCXO frequency stabilization (it is possible to use an external clock source, such as GPS) -Tangent support Yaesu MH-36 и MH-48 -And other..
