Diy arduino and psoc based rf swr\wattmeter for any band hf through microwave depending on the coupler and detector modules you choose. Now the final bits have arrived for the swr meter module, i can do the final assembly. Arduino based simple swr and power meter. Reads output from a pair of power detector modules that you assemble into a box. As this 'monimatch' type of bridge is frequency dependant, the meter must be calibrated for every band. Arduino code that runs on the m5stack with graphics and buttons. Swr is easier than power because it is a ratio and the absolute values don't matter so much (within a certain range). The first sensor device i will use below is a power meter, but the only data critical to the tuning cycle is the relative magnitude of the two readings, used to compute the swr. Incluye el sensor en la misma caja. Turns counter for vacuum capacitor or roller inductor 24/12/2018 graat 0. Arduino rf power & swr meter.
In the arduino sketch, i compensate for the loss in the rf tap by altering the intercept point used for the power calculation. It is highly flexible and. Alternately, a coupler with diode detectors can also be used. See appropriate #defines in the pswr_x.h file, included in the source code. Medidor de roe con instrumento analógico de dos agujas.

The frequency range of this product is from 140 to 150 mhz, and from 430 to 450 mhz. Based on an arduino nano and the pcb is designed by vu3wjm, rahul (bitx20 initial pcb designer). As this 'monimatch' type of bridge is frequency dependant, the meter must be calibrated for every band. The same circuits can be used for the rf power coupler and the ad8307 as in the original power and swr meter project, however a few new builds are shown below. Because these meters are very expensive, a cheaper solution is presented here as a diy wattmeter based on a arduino nano board. These are simply tee'd off the wiring inside the meter where it connects to the switch.
