Given the great accuracy of the RSP RF meter, I wonder if there is a standalone ‘power meter app’ available? I run a directional coupler on the back of my HF amp, and the sample port is fed to the RSP via a step attenuator.
A simple app that takes the amount of dialed-in attenuation as in input and displayed the corresponding output power in Watts would be cool. With cat control it could follow the frequency of the HF rigs VFO etc. Probably beyond my ability to code, but thinking it would be nifty.
