MEPT - a WSPR beacon

Vielseitige WSPR Bake für mobile und stationäre Anwendungen

MEPT = Manned Experimental Propagation Transmitter

Es dauerte einige Monate - aber jetzt ist es (fast) fertig.

Das Baken Konzept beruht auf getrennten Modulen die nach den speziellen Anforderungen kombiniert werden können.

Anschlüsse:

• USB interface für die Windows Konfigurations Software
• serial interface zum Anschluss der GPS Maus
• SPI bus für die Datenübermittlung zwischen den Modulen
• ICSP for in circuit serial programming of the PIC processor

Ausstattung:

• 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
• Bänder (80m / 40m / 30m / 20m/ 17m / 15m / 12m / 10m / 6m)

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

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)
