just wondering if anyone might have experimented with using LimeSDR for testing frequency response of DIY filters besides using Gqrx panadapter/waterfall for this purpose, which does help but not good enough to allow fine-tuning. In my location FM stations are very strong and they ‘leak’ into HF bands. So, I built FM stop-band filter (80-110 Mhz) and just wanted to figure out if LimeSDR (or perhaps LimeSuite?) can be used to fine-tune it similar to how it’s done using VNAs.
Thanks & 73!
