i have 2 PLUTOs, on both of them i cannot get the FM range 88-108MHz on IIO?
1. I used the correct antenna, i use this antenna on a spectrum analyzer it works fine
2. i customized the chip AD936x, to get down the 70 MHz range
3. i use the slow attack mode for gain
4. i used with filtering (first FIR filter on filtertool) and with no filtering RF BW 250KHz
5. i use a ubuntu LTS18 Virtual machine on a windows10 desktop
What do you think the error could be?
