My current project

Ever tried to manually switch your antennas and bandpass filters 30 hours into a contest? I have been doing it for years. 🙂 (And I have been complaining about it for ages too)

But the solution is near:

band decoder 001 band decoder 002

This is the prototype for my new universal band decoder.

The hardware is an Arduino (in the pictures is a Mega, it will be replaced by a UNO r3 in the finished product) and 2 4×4 Driver Shields from Logos Electromechanical.

The goal is to switch my SixPak and my 2 Dunestar 600 band pass filters for SO2R.

The data comes from the pc (over the usb port) using the Open Two Radio Switching Protocol (OTRSP) which is supported by N1MM and DXLab logging software.

For now this is a work in progress,  so come back here soon to follow the evolution!
