DX FT8 – Portable GUI Tablet FT8 Transceiver

DX FT8 is a FT8 Digital mode capable HF QRPp GUI (Graphical User Interface) based multiband Transceiver.

It is an open source project with it’s design and software files available for public.

DX FT8 is abbreviation for Digital Xceiver for FT8.

Main aim of DX FT8 Transceiver Project is to create a highly portable stand-alone FT8 GUI Transceiver. Stand-alone aim is to create a user interface for working FT8 digital mode plus Multi band transceiver packed into one unit.

This creates an advantage for carrying one GUI based FT8 operation capable Transceiver unit and no longer needs to carry a PC or a laptop or tablet for GUI interface operation for FT8 with a classic transceiver.

This approach is quite appealing for smaller and lighter setups for backpacking for SOTA or POTA activation or as a travel transceiver with FT8.

Here are some highlights on DX FT8 Specifications:

DX FT8 Transceiver GUI (Graphical User Interface) and processing power comes from ST Micro STM32F746 DISCO Evaluation board. This is a ARM CORTEX based evaluation board for STM32F746 micro controller.

DX FT8 Transceiver operates on 5 HF bands or 7 HF Bands depending on PCB type.

DX FT8 TRANSCEIVER uses an unconventional RF power Amplifier consisting of a TTL octal buffer IC and step up RF Transformer. There is no conventional MOSFET PA transistors. This creates an extremely resilient RF PA for failure due to high SWR or no antenna accidental operations. This is an advantage for portable operations as antenna conditions can vary.

DX FT8 TRANSCEIVER incorporates a TAYLOE detector based Quadrature Sampling detector receiver with a high gain RF Preamplifier which outputs an I and Q phase output to STM32F746 DISCO board which generates true Upper Side Band (USB) SSB receive signal.
