Any answer? Hello?
I agree it would be useful. I only think an SWR meter is feasible. A VNA would require two HackRFs and some extensive hardware modifications.
For an SWR meter using a noise source, it sounds like what is needed is a baseline difference function on the spectrum display. A sweeping spectrum analyzer like what is done with hackrf_sweep would be useful to extend the frequency range of the analyzer beyond the 20MHz bandwidth of the baseband ADCs.
Hello, is there any way to add to Portapack firmware SWR/VNA menu/option in future? I found that HackRF/SDR can be user as SWR meter with cheap noise source - https://www.rtl-sdr.com/measuring-the-swr-of-fpv-antennas-with-an-rtl-sdr/ https://www.rtl-sdr.com/rtl-sdr-tutorial-measuring-filter-characteristics-and-antenna-vswr-with-an-rtl-sdr-and-noise-source/ Also found on GitHub some hackrf_antenna_swr_utility - https://github.com/coddingtonbear/hackrf-antenna-swr-utility/tree/master/hackrf_antenna_swr_utility I think it would be nice and useful option if it possible. Thank you!
