Re: fl2k - low samplerate/ no rf-output

Hello Gang ;) i have some troubles, properly "misusing" my vga-adapter. the samplerate while testing with fl2k_test is pretty low (~50MS/s) and i am not sure if this is some hardware issue or. RF-Output isn´t detectable either. i am using a lenovo thinkpad x1 hybrid (1294). any help is appreciated. $ fl2k_test -s 162e6 Reporting PPM error measurement every 10 seconds...
