Home Made HF/50MHz DC Transciever

Husarek DSP is HF + 6m all modes home made direct conversion transceiver, designed by Janusz SP5BMP (hardware) and Tomasz Korniluk (software) in 2016. The heart of this transceiver is Discovery STM32F746G module. This module has a 4.3" LCD touch screen and an excellent 24-bit codec along with a power amplifier. It controls the whole functions of this transciever via the I2C bus and performs DSP filtering. The following filters can be attached: 2.5 kHz, 2.2 kHz, 1.9 kHz, 1 kHz, 500 Hz, 200 Hz and 100 Hz, and three AGC time constants for each emission SSB, CW, AM and FM. On the transmitting side, you can select the compression ratio in the range: 1, 2, 4 or 8. A telegraph key is also built-in this transceiver, as is the possibility of connecting a hand-held key. A characteristic feature of the device is that it has only one knob that controls the encoder. Other settings can be changed using the touch display. Output RF power is 15 watts on all bands.
