VERSATILE WSPR BEACON for MOBILE and FIXED applications
MEPT = Manned Experimental Propagation Transmitter
Es dauerte einige Monate - aber jetzt ist es (fast) fertig.
A versatile beacon concept that consists of a number modules that can be combined according to the application.
Anschlüsse:
- USB interface für die Windows Konfigurations Software
- serial interface zum Anschluss der GPS Maus
- 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
Here you can find an overview of the possible configurations
A detailed description of the individual modules can be found here
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)
