MEPT - a WSPR beacon


VERSATILE WSPR BEACON for MOBILE and FIXED applications

It took me a couple of month - but now it's (almost) ready.

A versatile beacon concept that consists of a number modules that can be combined according to the application.

Connectors:

  • USB interface to connect to a Windows application for configuration
  • serial interface to attach a GPS mouse
  • SPI bus to interconnect the modules
  • ICSP for in circuit serial programming of the PIC processor


Features:

  • Configuration software for Windows
  • Beacon runs independent from PC
  • Time and Location can be derived from GPS signal
  • Autonomous generation of WSPR data string in local microcontroller
  • Up to 8 different filters selectable through filter switch box
  • Up to 4 Attenuator networks selectable through attenuator switch box
  • Multiple DDS & PA modules attachable to one controller
  • DDS & PA module for 1.8-50MHz with up to 15W



At the moment there are two modules. The CPU box with a DDS/PA module and a switch box that can hold up to 8 filter and one attenuator modules

I have a long list of improvements and additions I want to create to my beacon system. Here is a list of my plans (Although I don't know yet where to find the time to do all that)
