SWR meter #2094

Hello, just wondering: would it be possible to measure SWR readings for the antenna attached to the HackRF on a specific frequency? I don't know if the HackRF chip or the Portapack one can provide SWR readings but, as we can receive and transmit in a huge frequency range, it would be great to be able and test our specific antennas to fulfil our needs at their best. Then - but I think we shouldn't worry too much about it, as tx power is very low - we could safely tx withouth the risk of burning the final RF transistors.

Similar to a VNA??? That'd be a great addition if it was possible for sure... being able to tune antennas and pair one for a specific use would be incredibly useful for HRf...

All available metrics are already exposed, and I don't think we can measure SWR from within the portapack.
