All-band HF direct conversion transceiver QRPver DC-3001 Minion Mini

Transceiver direct conversion, short-wave, all-band. QRPver Minion Mini DC-3001

This is a small-size multi-band short-wave QRP transceiver.

The transceiver is built according to the transceiver scheme with direct frequency conversion.

The device is controlled by the microcontroller STM32F100. As a local oscillator, a frequency synthesizer is used on the SI5351 chip

This transceiver is designed to work in the lower (LSB) and upper (USB) sideband by both a telephone (SSB) and a telegraph (CW). It is possible to work in digital communication modes (DIGI).

On board the transceiver there is a USB (UART to USB) port for connecting to a computer to control the transceiver from amateur programs, using the CAT protocol “Kenwood TS-440”

The transceiver has small dimensions of 100x103x30 mm. and a light weight of 430 grams. It will suit both for work on the field trip, on nature, at the dacha …. So for everyday work, at home.
