Power meter

I worked a bit on one of my other projects today for the station. I changed the micro controller on the board since I managed to break the other one and started to do some programming. The power meter will be compatible with various pickups with various power ranges. The input voltage to the input board is maximum 10V (peak to peak) and when larger voltages are used the scaling is done inside the pickup. As an example the pickup I made can measure 6W reflected power at 5kW forward power, so the attenuation between the ports is very high.

Here are some pictures, the power is just a simulation, not the actual power 🙂

I will do some more work on this device during poor weather when no outside work can be done. I will also then try it for real with RF power and see how it acts.
